Weather Terms RVers Need to Know

All the winter storm advisories, alerts, watches, and warnings that we’ll soon start seeing can be confusing. The National Weather Service does a great job of disseminating weather predictions but sometimes it can be hard to know just what is what.

In the year 350 B.C., the Greek philosopher Aristotle gave one of the earliest descriptions of weather patterns in a text called Meteorologica. It included some of mankind’s first attempts to observe and record natural phenomena like water evaporation and earthquakes. Although it was a far cry from the Weather Channel, Meteorologica was the start of something that had eluded human beings for time immemorial: the ability to understand—and even predict—the weather.

Modern weather forecasting is a $7 billion-a-year industry—and for good reason. Despite all the advanced technology of modern society, humans are still pretty much at the mercy of the elements. America’s GDP can fluctuate by more than $1.34 trillion depending on the weather. In 2020 alone, more than 60,000 weather events killed 585 people in the United States and injured more than 1,700 more with flash floods, tropical storms, heat, tornadoes, ice storms, and thunderstorms doing most of the damage.

Weather forecasters are easy targets because, like football referees, people tend to take notice only when they get it wrong. The reality, however, is that meteorologists are right in astonishing percentages. When weathermen and women issue seven-day forecasts, they’re accurate about 80 percent of the time—90 percent for five-day forecasts.

If someone had told Aristotle that human beings would one day be able to accurately predict the weather nine times out of 10, five days in advance, he likely would have laughed at their overactive imagination.

It’s important to note that climate and weather are not interchangeable terms. Weather describes the short-term—day-to-day and hour-to-hour—state of the atmosphere including temperature, precipitation, wind, and visibility. Climate, on the other hand, measures average weather patterns over several decades.

I used a variety of scientific sources to compile this list of common weather terms that RVers should know and understand.

Atmospheric pressure

Humans inhabit the very bottom of the Earth’s atmosphere and everything above creates atmospheric pressure. High-pressure systems form when downward pressure creates a clockwise air rotation, unlike low-pressure systems which generate counter-clockwise rotation. Both phenomena which are measured with barometers are critical to predicting weather events.

Black ice

Vehicle accidents are the leading cause of winter-related fatalities so when a meteorologist warns about the potential for black ice drivers should take it seriously. Black ice gets its name because it’s so thin that it’s nearly invisible on the road surface but the ice itself isn’t black. Black ice forms when sudden temperature increases causing snow to melt and drip onto roadways that are still cold enough to make the liquid water freeze on contact.

Blizzard

Not just any big snowstorm qualifies as a blizzard. A storm must meet three criteria to earn the harshest classification in winter weather. Blizzards have frequent wind gusts of at least 35 mph, sustained falling or blowing snow that reduces visibility to less than a quarter-mile, and these conditions are maintained for at least three consecutive hours.

Breezy and windy

The terms windy and breezy are sometimes used interchangeably but they don’t describe the same phenomenon. Breezy conditions involve air moving between 12 and 22 mph during pleasant conditions. Windy days, on the other hand, involve stronger winds up to 50 mph during stormy or inclement weather.

Dew point

The dew point represents the temperature to which air would have to be cooled to reach a level of moisture saturation. When it reaches the dew point, droplets of water or dew begin to form on solid objects like grass and vehicles.

Drought

Most people know droughts result from an extended lack of precipitation and abnormally high temperatures but overpopulation and land overuse are contributing factors, too. Droughts are among the most destructive forces in nature—only hurricanes are more economically damaging to the United States.

El Niño

The opposing warm half of ENSO is called El Niño (The Boy) which occurs irregularly every two to seven years and is often followed closely by a La Niña (see below) pattern. It warms the oceans and creates the opposite effect in terms of not just ocean temperatures but atmospheric pressure. It, too, is associated with irregular and sometimes severe weather patterns.

Flash flood

Flash flooding occurs when large amounts of water from sudden torrential rains—or occasionally an incident like the breaking of a dam—gushes through a narrow area that isn’t capable of absorbing high volumes of water. In many cases, flash floods which can roll cars and destroy houses happen in the immediate aftermath of extended droughts where parched land can’t absorb the influx of water quickly enough.

Flood crest

Flooding is one of the deadliest and most destructive weather phenomena in the country and on the planet. Weather professionals use specific terminology to describe rivers as they rise from excess water. A flood crest is the peak—the highest level the water will rise—which is the most significant and dangerous time of a flood but also an indication that the flood will soon recede.

Freezing rain

Freezing rain is formed through the same general process that creates sleet (see below) but they’re not the same thing. Sleet falls to the ground as ice. Freezing rain, on the other hand, remains in liquid form until it hits a cold object and then instantly freezes on contact.

Frost

Gardeners make their plans according to the first and last frost schedules in their respective agricultural zones. The frozen version of dew, frost occurs when cold, moisture-soaked air deposits water that freezes and leaves an icy film on things like plants and car windows.

Hail

Unlike sleet (see below) which is ice formed by rain falling through very cold air, hail is a much more dangerous phenomenon associated with much more dangerous weather. Hail forms when powerful updrafts inside of thunderstorms force water well above the freezing level. That water freezes into large hailstones which eventually become too heavy for the updraft and come crashing down to Earth.

Haze

The dreaded three H’s are hazy, hot, and humid. Hot is self-explanatory, humidity deals with the level of moisture in the air but what exactly does it mean to be hazy? A haze can look like a thin fog but it isn’t caused by precipitation. Hazy conditions occur when large amounts of fine, dry particulate matter like dirt are suspended in the air which scatters light and gives the lower atmosphere a cloudy appearance.

Heat index

The heat index is essentially the same thing as the wind chill factor (see below) but for the opposite sensation of environmental exposure. It represents how hot the temperature feels when humidity is considered. The more humid the air, the less perspiration can evaporate which cripples the human body’s cooling system and makes it feel hotter when it’s humid outside.

Heat wave

Heat waves are long periods of abnormally warm weather. To qualify as a heat wave, it must last for at least two days and consist of temperatures that are outside the region’s historical average.

Ice storm

Ice storms are extended episodes of freezing rain that occur when precipitation falls in liquid form and freezes on contact. It becomes an ice storm when a quarter-inch or more of ice accumulates creating dangerous conditions. Ice storms which can be deadly and cause a lasting impact can add 500 pounds to the weight of power lines and increase the weight of tree limbs by a multiplier of 30.

Jet stream

Jet streams are thin but intense winds in the highest reaches of the atmosphere. Following the boundaries of cold and warm air, jet streams blow west to east although their flow sometimes shifts to north and south. Not only do these rivers of air affect global weather and help meteorologists identify atmospheric patterns but they’re crucial to air travel as flying into and out of them can dramatically affect fuel consumption and flight time.

La Niña

One half of the El Nino-Southern Oscillation (ENSO) phenomenon, La Niña (The Girl) is a global weather pattern that describes a dramatic cooling of ocean temperatures in the Western Hemisphere. La Niña is known for its disruptive impact on weather specifically heavy rainfall and an increase in low-pressure systems.

Microburst

Microbursts are among the most dangerous and unpredictable weather phenomena on Earth and they form inside of already-dangerous thunderstorms. Updrafts—columns of rapidly rising air—sometimes suspend large amounts of rain and ice and when the updraft weakens, there’s nothing left to hold all that water and ice in place. That leads to a massive downdraft which sends the core of the column crashing to the ground and, upon impact, bursting out in all directions, leading to tornado-like winds, pressure, and destruction.

Nor’easter

Nor’easters are major, dangerous storms that are exclusive to the Northeastern United States. Geography, however, is not where these storms get their name. Nor’easters are named for the direction in which the storm’s most intense winds blow. Those winds are usually severe and they’re known to bring rain and snow and cause flooding and storm surges.

Polar vortex

The menacing phrase polar vortex is a relatively new term for winter weather forecasting but meteorologists have understood it as a concept for decades. A polar vortex occurs when a large section of very cold air, usually the coldest in the entire northern hemisphere, is pushed down the North American continent as far south as the Midwestern and Northeastern United States.

Relative humidity

Relative humidity is closely related to dew point (see above) but the two terms are not interchangeable. This term describes the amount of atmospheric moisture that exists relative to the amount that would exist if the air was saturated.

Severe thunderstorm

There are garden-variety thunderstorms and severe thunderstorms and when meteorologists mention the latter, the public should take it seriously. To be classified as severe, thunderstorms must include two potentially deadly elements: winds of at least 58 mph and hail at least one inch in diameter.

Sleet

One of the more unpleasant precipitation events associated with winter is sleet which stings the skin and turns roads and sidewalks into ice-skating rinks. Sleet graces the world with its presence when rain or melted snow freezes and turns into ice on its way from the sky to the ground.

Storm surge

It’s common to hear meteorologists warn that storm surge is one of the deadliest and most dangerous parts of major weather events like hurricanes. The phenomenon occurs when significant storms cause an abnormal rise in seawater above the limits of the astronomical tide. Storm surges can cause rapid, significant, and deadly flooding in coastal regions.

Tropical depression

Before a weather event graduates into a tropical storm, it’s a tropical depression. The infant stage of a hurricane, a tropical depression is a tropical cyclone with maximum sustained winds up to 38 mph.

Tropical storm

People sometimes use the terms tropical storm and hurricane interchangeably but one is an evolution of the other. Tropical storms form in the same places and under the same conditions as hurricanes but they achieve maximum sustained wind of just 39–73 mph. If a tropical storm’s maximum sustained winds hit 74 mph, it becomes a hurricane.

Watches and warnings

Meteorologists issue precautions to inform residents about the likelihood of serious and fast-moving weather events like tornadoes and severe thunderstorms. Watches are less serious and indicate that conditions are present for the formation of a severe weather event. Warnings, on the other hand, indicate that an event has been identified by a person or radar, a tornado or thunderstorm is imminent and to seek shelter immediately.

Wind chill

Everyone in North America north of a certain latitude knows there are two temperatures they have to consider when getting dressed in the morning in winter—the actual temperature reading and the one that counts: the wind chill factor. Also known as the feels-like temperature, wind chill represents how cold the weather feels on human skin when the chilling effect of the wind is taken into consideration.

Wintry mix

Two words cold-weather commuters never want to hear are a wintry mix. When precipitation travels through an above-freezing warm layer of air followed by a cold, below-freezing layer, snow, sleet, and freezing rain can fall simultaneously.

Since we’re talking weather, here are a few related articles:

Are You Prepared for the Next Great Weather Event?

Educate yourself ahead of time. Every type of extreme weather event presents a unique challenge.

We know that weather can either make or break a camping trip. Sunshine and blue skies are what make RV trips a fun experience but we can’t always be that fortunate. Every once in a while a storm or unexpected temperatures sneak up on us and we must be fully prepared for when nature is having an off day. Extreme weather is more dangerous when in an RV than in a house. Here are some severe weather tips for RVers for when the going gets tough.

The most important thing to do is stay updated on the most current weather as much as possible to avoid surprises and prepare for any bad weather that may be on its way. Checking the weather before leaving on a road trip will provide some insight into what you may experience over the next several days.

As with any emergency, you want to be prepared ahead of time. Create an emergency plan for every situation and make sure your family knows the procedures. Write out the procedures and post them for future reference.

Seek shelter before the weather becomes extreme. No possession is worth more than you and your family. The worst thing to do is to wait around to determine the actions of others, wait for rescue, or wait until the last minute to know the severity of the weather event.

Prepare an emergency supply kit and place it in a convenient location that is easy to access. Consider including the following items: whistles, extra blankets, rain ponchos, non-perishable packaged/canned food, can opener, flashlights, a flare gun, a first aid kit, necessary prescription drugs, a compass, pet supplies/food, and bottled water.

Know the county you are located in and the surrounding counties. When you hear a weather alert message on your smartphone, radio, or television you’ll be able to determine where the storm is located and how quickly it will approach your current location.

The National Oceanic and Atmospheric Administration (NOAA) and National Weather Service (NWS) provide information on current conditions, incoming storms, and emergency radio station lists. Have an NOAA battery-operated alert radio with an automatic alert mode, smartphone charger, and several flashlights in your RV? Top-rated mobile weather apps include WeatherBug, AccuWeather, and The Weather Channel.

Lightning and thunderstorms

According to NOAA, at any given moment in the day there are roughly 2,000 thunderstorms in progress across the globe. The United States experiences 100,000 thunderstorms every year with spring and summer afternoons seeing the highest frequency of events. Each storm can bring a suite of problems from hail to high winds but it’s lightning that is your number one concern.

Be prepared for severe weather © Rex Vogel, all rights reserved

Key points to keep in mind include:

  • Lightening kills more people annually than tornadoes or hurricanes
  • Taking shelter inside any building or vehicle is safer than being outside
  • Rain does not signify the beginning of a dangerous storm; thunder does
  • Anytime you hear thunder you’re at risk of a lightning strike; close your awning, store anything that can blow away, and get indoors as quickly as possible
  • Lightning strikes can damage the electrical power in your unit so it’s a good idea to use an Electric Management System (Progressive Industries or Surge Guard)

Flash floods

The severity and speed of flash floods make them one of the most harrowing weather events adventurers might encounter. They occur when excessive water fills normally a dry canyon or wash and when creeks and rivers rise rapidly from rainfall within their watershed.

According to the National Severe Storms Laboratory, a creek that’s only six inches deep in the mountains can swell to a ten-foot-deep raging river in less than an hour if a thunderstorm lingers over an area for an extended period.

Key points to keep in mind include:

  • Do not attempt to cross any water higher than your ankles
  • As little as 6 inches of water flowing quickly can knock an adult down
  • Less than 2 feet of water can sweep a car away or stall it out with you stuck inside
  • You rarely have time to move your RV; get to higher ground and stay safe
  • TURN AROUND DON’T DROWN

Dust storm

Dust storms (also called Haboobs) are unexpected, and unpredictable, and can sweep across the desert landscape at any time. Dust storms can reduce visibility to near zero in seconds resulting in deadly, multi-vehicle accidents on roadways. Dust storms can be miles long and thousands of feet high. 

Dust storms can occur anywhere in the United States but are most common in the Southwest. In Arizona, dust storms most frequently occur during monsoon season (June-September) but they can pop up at any time of the year. Drivers of high-profile recreation vehicles should be especially aware of changing weather conditions and travel at reduced speeds.

Be prepared for severe weather © Rex Vogel, all rights reserved

Key points to keep in mind include:

  • DO NOT drive into or through a dust storm. PULL ASIDE. STAY ALIVE.
  • Do not stop in a travel lane or the emergency lane. Look for a safe place to pull completely off the paved portion of the roadway.
  • Turn off all vehicle lights including your emergency flashers. You do not want other vehicles approaching from behind to use your lights as a guide possibly crashing into your parked vehicle.
  • Set your emergency brake and take your foot off the brake.
  • Stay in the vehicle with your seatbelts buckled and wait for the storm to pass.
  • PULL OFF! LIGHTS OFF! FOOT OFF!

Tornados

Tornado Alley which stretches from mid-Texas north to North Dakota is plagued by a high frequency of tornadoes. But the disastrous storms aren’t just relegated to the plains. Tornadoes can happen anywhere. While tornadoes can form quickly—on average, NOAA releases a tornado warning in the potential impact area 15 minutes before the tornado hits—most are born from thunderstorms.

Key points to keep in mind include:

  • When you register at an RV campground, ask about the tornado and storm warning systems for the area
  • Never try to outrun a tornado in any type of vehicle
  • RVs do not provide good protection during a tornado
  • Be ready to go when a tornado WATCH is issued

Extreme Heat

Extreme heat poses a threat to young children, older adults, and anyone who doesn’t take the right safety precautions before and during a heat wave. Heat-related incidents can be prevented with a few measures to ensure that both you and your family can safely get through the heat wave.

Heat exhaustion and heat stroke need to be taken seriously. If you feel like you’re becoming dizzy, weak, or nauseous after spending time in the sun, take care of yourself as soon as possible. These conditions can quickly get worse if you ignore them. 

Be prepared for severe weather © Rex Vogel, all rights reserved

Key points to keep in mind include:

  • Limit your exposure to the sun
  • Stay hydrated by drinking at least 16 ounces of water every hour in the heat to replenish your body and prevent dehydration
  • Wear light, loose-fitting, breathable clothing; a wide-brimmed hat, correct shoes, sunscreen, and wet bandanas to keep you cool while in the sun
  • Be aware of the heat and humidity index (a relative humidity of 60 percent or higher makes it hard for sweat to evaporate off your body)

Hurricane

The devastating power of hurricanes can change your life, or even end it, in seconds. An RV is not a safe place to ride out a hurricane. Hurricanes pack enough punch to destroy everything in their wake and in those times it is best to be prepared for an immediate evacuation. Your RV can become your best friend and your ticket to safety if you take certain safety measures for yourself and your vehicle.

Be prepared for severe weather © Rex Vogel, all rights reserved

Key points to keep in mind include:

  • As soon as you know a hurricane is likely to come your way, load up your RV and head out before the Interstate becomes a virtual parking lot
  • Get as far from the coast and bodies of water as you can

Wildfires

Wildfires are highly unpredictable and can be deadly. With the severe heat, drought conditions, and wildfires burning across much of the western US states and Canada, those who are out adventuring need to be aware of wildfire conditions and what can be done to keep you and your family safe.

Over time, wildfires have become more prevalent. The changing climate makes droughts more frequent, generates more wind (which whips and spreads the flames) and leaves areas more susceptible to wildfires or the more dangerous and larger-scale mega-fires.

The peak month of wildfire season is August when areas become increasingly dry, hot, and more susceptible to wildfire. The states with the highest number of wildfires are California, Colorado, Texas, Florida, Arizona, Utah, New Mexico, and Oregon.

Be prepared for severe weather © Rex Vogel, all rights reserved

Key points to keep in mind include:

  • Know the current wildfire conditions and fire restrictions for the area you are traveling
  • Choose a campsite that has more than one escape route
  • If you do see an unattended fire or out of control fire, contact the authorities by calling 911 or the Forest Service immediately
  • If you are asked to evacuate, do so immediately

Blizzards/Snowstorms

The best advice is to stay off the road, sit tight, and wait the weather out. Risking your life or the life of your family is not worth it for a road trip. Keep snow tires/chains, extra blankets, and extra food and water. Check to ensure you have a full tank of fuel (which also helps to add additional weight), and check for correct tire pressure (low tire pressure increases the chance of hydroplaning).

Be prepared for severe weather © Rex Vogel, all rights reserved

Key points to keep in mind include:

  • Secure everything outside that has even the slightest potential to blow away
  • Keep a pair of thick gloves and a toque with you
  • Wearing multiple layers of light clothing will keep you warmer than one heavy layer

How Safe is an RV in a Lightning Storm?

Do RVs attract lightning?

How safe is an RV in a lightning storm? That’s a loaded question and one I’m here to answer. There are many myths about RVs and lightning. What’s important is that we’re all armed and ready to do what’s legitimately called for in a lightning storm when we’re in an RV.

Preparedness is everything where safety is concerned, so let’s get right to it starting with the most basic.

Skyline Ranch Resort, Virginia © Rex Vogel, all rights reserved

What is lightning?

According to the NOAA National Severe Storms Laboratory, lighting is defined as “a giant spark of electricity in the atmosphere between clouds, the air, or the ground”.

In short, lightning is an extremely powerful electrical discharge that occurs during a thunderstorm. When lightning strikes the air becomes extremely hot—and when I say “extremely hot” I mean around 50,000 degrees F—far hotter than even the surface of the sun!

The thunder you hear is the heated air the lightning is passing through expanding quickly. Effectively, it’s like the boom generated by a supersonic plane.

Lightning can occur between clouds (cloud to cloud), from cloud to air, or from cloud to ground. Cloud to the ground is the type of lighting we’re most concerned about as it’s the most dangerous to us while we’re in our RVs.

Now let’s get into how safe an RV is in a lightning storm.

Capitol City RV Park, Montgomery, Alabama © Rex Vogel, all rights reserved

How safe is an RV in a lightning storm?

There’s no getting around it—lightning storms can be extremely dangerous. If you’re in an RV, the key to your safety depends on the materials your rig is made of and the actions you take.

First, if your RV’s frame or roof—or the entire skin/outer structure—is made of metal/aluminum/steel you should be safe from lightning when you’re inside. Your electronics may take a hit unless you’ve disconnected them but the people inside the rig should be safe. And the good news is that many if not most modern RVs do have a metal frame.

More on severe weather: 6 Things You Need To Know about Camping in a Storm

If your rig has a roof made of aluminum or steel you’ll likely be safe inside your RV in a lightning storm. And if your RV roof is made of fiberglass but the frame of the rig is made of steel you’ll still be well protected.

If your RV is made entirely of other materials like wood or all-fiberglass then you’ll be safer inside your tow vehicle/toad. Contrary to popular belief, metal doesn’t attract lightning but it is very much capable of reducing its destructive impact by channeling it away and toward the ground.

And when metal forms a “cage” of sorts, it offers even more protection. More on that in just a moment. First, another note about metal.

Quail Ridge RV Park, Huachuca City, Arizona © Rex Vogel, all rights reserved

Is it true that lightning only strikes metal?

Nope, that’s a myth. Lightning isn’t drawn to metal and it certainly doesn’t only strike metal. In fact, experts with the National Weather Service agree that metal has no bearing on the attraction of lightning.

In fact, the height of an object, the shape of an object (pointy), and isolation are the three primary factors that determine where lightning is most likely to strike. We’ve heard of lightning striking trees, for example. That’s because they tend to be all three things: tall, pointy, and isolated from other tall objects.

Skyline Ranch Resort, Virginia © Rex Vogel, all rights reserved

What is a Faraday Cage?

So, the metal “cage” structure of cars provides particular protection against lightning due to a concept known as the “Faraday Cage”. This would also be true of any RV with a metal frame/“cage” but not all RVs are built in this way. So, if your rig doesn’t have steel/aluminum framework you should seek shelter elsewhere immediately.

Essentially, the Faraday Cage refers to the fact that a car is a large metal cage that conducts the lightning AROUND the outside metal instead of THROUGH the inside of the car. This isn’t new information. This goes all the way back to Benjamin Franklin in the mid-1700s. The principle was refined by a scientist named Michael Faraday in 1836 thus the name “Faraday Cage”.

The first takeaway here is clear: the protection offered by the Faraday Cage effect is the reason you’re safe inside a car during a lightning storm. Again, the same would apply to an RV with a metal frame or roof but if you’re camping in an RV made of other materials such as only wood and fiberglass, seek shelter elsewhere in a lightning storm.

However, the second important thing to remember is that the presence of the Faraday Cage doesn’t mean that the vehicle can’t be struck by lightning or impacted by lightning. It means that you’re safe INSIDE the vehicle (so long as you’re not in contact and/or close proximity to any metal connected to that outer “cage”).

If you’re outside of a vehicle that has been struck, DO NOT touch the vehicle. The people inside are safe. But if you touch the vehicle, you may not be. If the strike has just occurred and the metal is still electrified you could be shocked if you walk up to the vehicle or touch it.

Skyline Ranch Resort, Virginia © Rex Vogel, all rights reserved

What should I do if I’m inside my RV in a lightning storm?

How safe your RV is in a lightning storm will largely depend on what you do. There are several protective actions you can take if you’re inside your RV during a storm. 

One of the most important things you can do to protect yourself is something you can do right now and that is to learn something about the construction of your RV so that you’ll know when the time comes whether you’re safe to remain inside your rig or whether you need to take shelter in your toad/tow car.

More on severe weather: Lightning and Thunderstorms: Safety Tips for RVers

Here are several other actions you can take to increase your safety in a lightning storm:

Irwins RV Park, Valemount, British Columbia © Rex Vogel, all rights reserved

Move away from trees

Always move away from trees. This is very important. Not only can trees or branches fall onto your RV in windy storm conditions but trees are tall and pointy and sometimes isolated. You may recall that these are the three most likely factors to attract a lightning strike.

You don’t want to be near trees in your RV during a lightning storm. Even if you’re taking shelter in a car, move that car away from trees. While you may be perfectly safe from the lightning itself inside a car or RV, you’re not safe from falling trees. And being crushed is likely no more fun than being electrocuted!

Mount Washington Cog Railway, New Hampshire © Rex Vogel, all rights reserved

Move away from water

Water isn’t safe in a lightning storm. Lightning strikes the water with some regularity. And water conducts electricity. This is why it’s particularly important to know the weather forecast before you head out on the water in a boat, kayak, canoe, paddleboard, or another vessel. It is unsafe to be on the water in a lightning storm.

If your RV is parked on the beach, lakeside, or riverside, move your RV up to a parking area or other safe location. Just remember to look around for flag poles, light poles, trees, and other tall, pointy structures, and stay away from them as well.

Unplug your RV from electrical outlet

In preparation for a lightning storm, one of the first things you’ll want to do is disconnect your RV from any electrical outlet. DISCONNECT the RV from the electrical outlet before the storm comes close.

The reason for this is to protect your RV’s electrical system and the electrical/electronic components connected to it from potentially damaging surges caused by lightning striking nearby. So, if possible, unplug appliances and disconnect or shut down electronics.

More on severe weather: Hail Can Be a Killer Especially For Your RV

Again, if you’re inside an RV with a metal roof or metal frame, or if you take shelter in your tow vehicle or elsewhere, you’ll be safe. But to avoid damaging your RV’s electronics, you’ll want to be as disconnected as possible.

Bring in awnings and bring down antennas

Antennae are the tall, pointy, isolated lightning attractors I warned you about earlier. Bring them in ahead of the storm and store them safely. Awnings should never be left out in inclement weather, anyway… since wind or heavy rain can easily damage them.

Irwins RV Park, Valemount, British Columbia © Rex Vogel, all rights reserved

Stay in the center of the RV away from windows and doors

During the storm remain in the center of your RV as far away from windows and doors as practical. Doors and windows are the least safe zones of your RV and staying away from them mean you’re safer.

This is due to two things: (1) window and door frames are almost always metal and as such are a point for you to come into contact with electricity from a lightning strike and (2) high winds from the storm could hurl objects into/through the windows potentially injuring you.

Keep your family, pets included, in the center of the rig until the storm passes.

Stay abreast of weather information using a smart phone or Emergency Weather Radio

The ability to stay informed of the storm’s arrival and passage is critical. Your smartphone may be capable of delivering that information to you via apps like Storm Shield or NOAA Weather Radar Live (look for the “Clime: NAA Weather Radar Live” app in your device’s app store) can keep you abreast of important information. However, if a cell tower is rendered incapable of offering you a connection or if you’re simply not in an area where you have good cell service your smartphone won’t be useful.

More on severe weather: 5 Tips for Avoiding Extreme Weather While RVing

For this reason, it’s always a good idea to travel with (or even to have at home) an emergency weather radio. Some are able to operate on batteries and/or by crank and will give you access to AM radio stations and emergency broadcasts.

Drive to a stronger shelter

And finally, if you’re not safe where you are, you need to drive to a stronger shelter. If you can get to a department store or any type of public building to take shelter, you’ll be increasing your safety and that of your family members.

Surely this goes without saying, but I’ll say it anyway—never, ever leave pets in your RV if you take shelter in another building. Even if pets aren’t typically allowed in a grocery store where you’re taking temporary shelter, for example, bring your pets with you but be sure to keep them leashed or caged (depending on the pet), and keep complete control of your pets at all times inside the building.

6 Things You Need To Know about Camping in a Storm

Survival tips for RV camping in storms and bad weather

Spring and summer storms can make RV camping a scary experience rather than the fun and pleasant one it should be. 

What’s an avid camper to do? Fortunately, there are ways to ensure you and your family stay safe while also fully enjoying the camping season. Here are my top tips for camping during storm season.

By avoiding areas such as Oklahoma, Texas, and Kansas during tornado season and places where hurricanes tend to crop up during hurricane season you can reduce your risk by quite a lot. Instead, choose to travel to those areas during other times of the year and focus on different destinations during times when storms are likely to come around.

2. Pay attention to weather reports

No matter when or where you decide to travel, you need to pay attention to the weather forecast. Knowing if and when a storm might crop up is important because it allows you to watch for it and get out of harm’s way if needed be. I recommend keeping a weather radio on hand for this purpose.

More on severe weather: Lightning and Thunderstorms: Safety Tips for RVers

It’s also a good idea to install an app such as Weather Bug on your smart phone. This app will send you an alert should severe weather be headed your way.

3. Stock up on the right supplies

Besides your weather apps and a hand-crank weather radio, there are a few other things you’ll want to keep on hand just in case you end up camping in a storm. These include:

  • Flashlight and spare batteries: This will help you see should the power go out
  • First aid kit: You never know what kind of injury you might need to tend to
  • Water: Being thirsty in a storm shelter is no fun; avoid it by packing bottles of water and be sure to stay hydrated
  • Snacks: In case you get hungry while waiting out a storm, you’ll be glad to have a few non-perishable snacks on hand

I recommend putting all these things into a tote bag. This should be kept in an easily accessible location near the exterior door. It will ensure you’re well prepared. Then you can get to safety quickly.

Make sure your family is fully dressed with closed-toed shoes. Grab your smart phone and any important documents in the rig. Then head to shelter. If you can, grab helmets and/or pillows to cover your head. They also protect you from flying objects.

4. Know where to go

Of course, if you’re going to head out when the weather gets bad, you don’t want to be confused about where to go. Always establish where you will go in case of a storm when you arrive at a new campground. 

More on severe weather: 5 Tips for Avoiding Extreme Weather While RVing

Numerous RV parks in tornado alley have storm shelters. As an alternative, head to a bathhouse or another sturdy structure with as few windows as possible. 

When you get to the place where you will wait out the storm, find a place that is far from windows and potential projectiles. Wear your helmets. Keep your important items under you. Use the weather radio to track the storm. Have your pillows close at hand in case you need them.

5. Check your site

If you have enough notice of an impending storm, there are also several things you can do. If you plan to stay in your rig while camping in a storm, following these fairly simple steps can make a big difference. Take time to follow them. They include:

  • Take pets inside: Dogs and cats deserve a safe, dry place to weather the storm as much as you do—take them to the shelter with you
  • Remove projectiles: If you have chairs or other potential projectiles on your site, stow them; you don’t want one to go through a window
  • Close storage bay doors: Ensure your storage bay doors are closed and secured
  • Retract the awnings: RV awnings can’t stand up to much wind and rain. Keep yours intact by retracting before any kind of storm. As a word of caution, always retract the awning when leaving your rig or retiring for the night.
  • Close the windows: Obviously, you’ll also want to make sure all windows are closed and securely latched
  • Park away from trees: If possible, move your RV out from under trees that could break and fall on your roof causing extensive damage
  • Retract the slides: Slides can catch the wind causing an entire trailer or motorhome to flip
  • Fill the water tank: If it’s going to be very windy or if a tornado is headed your way consider filling your tanks to add more weight to your rig

6. Use common storm sense

Of course, you’ll also want to use your common sense when it comes to storms. Don’t hang out outdoors in a lightning storm. Avoid pools or other bodies of water. Especially if there is lightning in the area. If there is hail, get away from skylights and windshields.

Finally, you will want to watch for flooding and evacuate quickly. Head for higher ground if it looks like water is headed your way.

Flash Floods: Safety Tips for RVers

TURN AROUND DON’T DROWN

Historic rainfall around St. Louis, Missouri on Tuesday (July 26, 2022) led to flash flooding that submerged cars in a river of water on Interstate 70 and trapped people inside their homes. Flash flooding led to numerous road closures across the St. Louis metropolitan area after a record-setting 6 to 10 inches of rainfall caused widespread flash flooding, the National Weather Service’s (NWS) office in St. Louis reported. St. Louis recorded 8.06 inches of rainfall in five hours since midnight shattering the city’s old daily rainfall record of 6.85 inches logged in August 1915, the NWS said.

Devastating flash floods throughout eastern Kentucky have left eight residents dead, dozens of homes submerged in water, and others completely swept away from their foundations. Multiple counties across Appalachia Kentucky have endured torrential rains since early Thursday morning (July 28, 2022) as floodwaters began rushing down the hillsides and completely swallowing up portions of the Kentucky River sending residents searching for high ground until rescue teams could save them.

Airports, parking lots, and the entire Las Vegas Strip which houses some of the world’s most famous casinos and hotels were also flooded Thursday. Heavy rain filled countless buildings as the city put a flash flood and severe thunderstorm warning in place.

People often have a hard time envisioning the power of moving water. Each year when heavy rains pummel North America’s deserts or mountains, another camper endures a flash flood camping weather disaster. Those who live to tell about it are shocked to learn how these torrential storms can destroy everything in its path—including RVs.

The severity and speed of flash floods make them one of the most harrowing weather events adventurers might encounter. They occur when excessive water fills normally a dry canyon or wash and when creeks and rivers rise rapidly from rainfall within their watershed.

According to the National Severe Storms Laboratory, a creek that’s only six inches deep in the mountains can swell to a ten-foot-deep raging river in less than an hour if a thunderstorm lingers over an area for an extended period of time.

More on severe weather: Lightning and Thunderstorms: Safety Tips for RVers

According to the National Weather Service (NWS), flash flooding can happen nationwide. It is also the number one weather-related killer in the U.S. On average, 86 people die each year because they attempted to drive through floodwaters—and unfortunately, that number is increasing.

It takes as little as six inches of water for a vehicle to be swept away.

According to FEMA:

  • Six inches of water will reach the bottom of most passenger cars causing loss of control and potential stalling
  • One foot of water will float many vehicles
  • Two feet of rushing water will carry away most vehicles including SUVs and pickups

According to the U.S. Geological Survey, water one foot deep typically exerts 500 pounds of lateral force on a vehicle. Once your vehicle is floating, the floodwater becomes your steering wheel. If that water is moving, your vehicle could be swept away, tipped on its side or flipped.

Rising water can enter your vehicle in a manner of minutes, even seconds.

Evacuation following a flash flood at Catalina State Park, Arizona © Rex Vogel, all rights reserved

The best advice is never to drive through flood waters of unknown depth. As the NWS has campaigned for years: TURN AROUND DON’T DROWN!

NEVER try to walk, swim, or drive through such swift water. If you come upon flood waters, STOP! TURN AROUND AND GO ANOTHER WAY.

More on severe weather: 5 Tips for Avoiding Extreme Weather While RVing

Some people risk destroying their vehicles and potentially losing their lives by driving through floodwaters. It’s a scary experience to come across rising water on the road during a rainstorm, not knowing if you’ll stall out. It is not worth the risk!

What is Flash Flooding?

Flooding begins within six hours and often within three hours of heavy rainfall (or other cause). Flash Floods can be caused by several things but are most often due to extremely heavy rainfall from thunderstorms. Flash Floods can occur due to dam or levee breaks and/or mudslides (debris flow).

The intensity of the rainfall, the location, and distribution of the rainfall, the land use and topography, vegetation types and growth/density, soil type, and soil water content all determine how quickly the flash flooding may occur and influence where it may occur.

Flash Flooding occurs so quickly that people are caught off-guard. Their situation may become dangerous if they encounter high, fast-moving water while traveling.

Evacuation following a flash flood at Catalina State Park, Arizona © Rex Vogel, all rights reserved

How do Flash Floods occur?

Several factors contribute to flash flooding. The two key elements are rainfall intensity and duration. Intensity is the rate of rainfall and duration is how long the rain lasts. Topography, soil conditions, and ground cover also play an important role.

Flooding along rivers often occur seasonally when spring rains coupled with melting snows fill river basins with too much water, too quickly. Torrential rains from hurricanes or tropical storms can also produce river flooding.

More on severe weather: Severe Weather: Tornado Safety Tips for RVers

Occasionally, floating debris or ice can accumulate at a natural or man-made obstruction and restrict the flow of water. Water held back by the ice jam or debris dam can cause flooding upstream. Subsequent flash flooding can occur downstream if the obstruction should suddenly release.

Flash floods occur within a few minutes or hours of excessive rainfall, a dam or levee failure, or a sudden release of water held by an ice jam. Flash floods can roll boulders, tear out trees, destroy buildings and bridges, and scour out new channels. Rapidly rising water can reach heights of 30 feet or more. Furthermore, flash flood-producing rains can also trigger catastrophic mud slides. You will not always have a warning that these deadly, sudden floods are coming. Flash flooding occurs within six hours of the rain event. Flooding is a longer term event and may last a week or more.

Evacuation following a flash flood at Catalina State Park, Arizona © Rex Vogel, all rights reserved

Where do Flash Floods occur?

Flash Flooding is possible anywhere and everywhere. The normally tranquil streams and creeks in your area can become raging torrents if heavy rain falls overhead or even upstream of your location. Flash Flooding can also occur on city streets and highway underpasses.

Key points to keep in mind include:

  • Do not attempt to cross any water higher than your ankles
  • As little as six inches of water flowing quickly can knock an adult down
  • Less than two feet of water can sweep a car away or stall it out with you stuck inside
  • You rarely have time to move your RV; get to higher ground and stay safe

TURN AROUND DON’T DROWN

Choose campsites carefully to avoid flash flood camping disasters

Flash floods are especially common in the desert. But according to Scientific American, flash floods can happen in both urban and remote settings. Pretty mountain areas are especially vulnerable if the snow melts quickly after a rain storm. Other susceptible areas to worry about are recently burned hillsides.

More on severe weather: Excessive Heat Warnings: Safety Tips for RVers

Weather experts also say that fast-moving water can take out everything in its path—even the largest RVs. The risk is there but don’t let it keep you at home. If you know how to avoid a flash flood camping weather disaster in the first place, you can stay safe. The campsite you choose to park in is the best place to begin.

Disaster-proof your campsite

Many RVers love the adventure of wilderness camping. When wilderness RV camping, safety is very important. Don’t park your rig until you find a safe-looking site with a low risk of flooding.

Use common sense and pay attention to your local surroundings. Assess the area. If there’s even a small chance of rain, don’t camp in a canyon or near low spots or anywhere with steep mountain walls closing in on you.

Clean-up following a flash flood at Catalina State Park, Arizona © Rex Vogel, all rights reserved

Keep a weather band radio available especially when camping in storm-prone areas. Leave before a major storm is forecast to strike.

Check weather reports. Flash floods can strike miles from the origin of a storm. Don’t assume that blue skies overhead mean it is safe. Keep an eye on the weather forecast for your region.

Know your escape route. If rain starts falling and your gut instinct is telling you to leave, take a look around to find the fastest way out to safety.

If hazardous weather prompts evacuation warnings by officials, do what is requested. If you’re lucky enough to drive your RV out of the campground, don’t waste time taking your hoses, chairs, etc. Your sewer hose isn’t worth your life.

In conclusion

Preparing for weather oddities and calamities is part of the RV lifestyle. Nobody expects a flash flood camping disaster but things happen fast when the water rises and it only takes minutes for a deadly catastrophe. If all else fails and you still get trapped in a campground during a flash flood, don’t try to drive your way out of it. Run for the highest ground you can find and you just might live to tell about your dramatic flash flood campground evacuation.

Dust Storms and Haboobs: Safety Tips for RVers

Do you know what to do during a dust storm?

Don’t drive into a DUST STORM! Pull aside and stay safe. Stay Alive!

Dust storms (also called Haboobs) are unexpected, unpredictable, and can sweep across the desert landscape at any time. Dust storms can be miles long and thousands of feet high. You can endure these brief but powerful windstorms if you know how to react. 

Dust storms can occur anywhere at anytime © Rex Vogel, all rights reserved

Dust storms can occur anywhere in the United States but are most common in the Southwest.

In Arizona, dust storms most frequently occur during monsoon season (June-September) but they can pop up at any time of the year. If you’re in a vehicle and a dust storm is approaching, the most important thing to do is to not drive into the dust storm. That’s because visibility can drop to zero, leaving you and others driving blind and making for a dangerous situation.

If you encounter a dust storm and don’t have time to exit the highway, Arizona Department of Transportation (ADOT) has developed these “Pull Aside, Stay Alive” tips to help you know what to do.

BEFORE

Know Your Risk and Be Informed:

  • Dust storms are more common near agricultural areas and near Willcox Playa in Cochise County
  • Dust storms are more frequent in July and August and between 4:00 pm. and 6:00 pm
  • Dust storms can reduce visibility to near zero in seconds resulting in deadly, multi-vehicle accidents on roadways
  • Drivers of high-profile recreation vehicles should be especially aware of changing weather conditions and travel at reduced speeds
Dust storms can occur anywhere at anytime © Rex Vogel, all rights reserved

Familiarize yourself with these terms to help identify a dust storm hazard:

  • Dust Storm Watch: Tells you when and where dust storms are likely to occur. Watch the sky and stay tuned to NOAA Weather Radio or commercial radio for information.
  • Dust Storm Warning: Issued when visibility is ½-mile or less due to blowing dust or sand and wind speeds of 30 miles an hour or more.
Dust storms can occur anywhere at anytime © Rex Vogel, all rights reserved

DURING

Take action in a vehicle:

  • DO NOT drive into or through a dust storm. PULL ASIDE. STAY ALIVE.
  • Immediately check traffic around your vehicle (front, back, and to the side) and begin slowing down.
  • Do not wait until poor visibility makes it difficult to safely pull off the roadway—do it as soon as possible. Completely exit the highway if you can.
  • Do not stop in a travel lane or in the emergency lane. Look for a safe place to pull completely off the paved portion of the roadway.
  • Turn off all vehicle lights including your emergency flashers. You do not want other vehicles approaching from behind to use your lights as a guide possibly crashing into your parked vehicle.
  • Set your emergency brake and take your foot off the brake.
  • Stay in the vehicle with your seatbelts buckled and wait for the storm to pass.

More on severe weather: Severe Weather: Tornado Safety Tips for RVers

Dust storms can be scary but they usually pass fairly quickly and you can be on your way again.

PULL OFF! LIGHTS OFF! FOOT OFF!

Take action indoors:

  • Close your doors and windows.
  • Consider turning off air conditioning until the dust storm passes.
  • Check your camping site for chairs, tables, toys, BBQs, and other objects that can become projectiles in high winds. Bring them inside, tie them down, or secure them in some other way.
  • Make sure your outside storage doors are closed and locked.
  • Retract any awnings and ensure they’re securely fastened.
  • Bring pets indoors.
Dust storms can occur anywhere at anytime © Rex Vogel, all rights reserved

Take action outdoors:

  • Get as low to the ground as possible far away from roads and freeways
  • Dust Storms often accompany severe winds and thunderstorms which could lead to flash flooding
  • Avoid trees and low lying areas
  • Protect your face and any exposed skin
  • Cover your nose and mouth.
Dust storms can occur anywhere at anytime © Rex Vogel, all rights reserved

AFTER 

Stay safe, healthy, and alert:

  • If you are pulled over in a vehicle, check traffic, and carefully return to the roadway
  • Drive with caution
  • Anticipate traffic light outages and obstacles on the road
  • Report broken utility lines and damaged roadways/railways to appropriate authorities as soon as possible
  • Follow instructions from the National Weather Service about additional hazardous conditions that may be expected

Worth Pondering…

On the fourteenth day of April in 1935
There struck the worst of dust storms that ever filled the sky…
From Oklahoma City to the Arizona Line
Dakota and Nebraska to the lazy Rio Grande
It fell across our city like a curtain of black rolled down,
We thought it was our judgment, we thought it was our doom…

—Woody Guthrie, from his song, The Great Dust Storm

Lightning and Thunderstorms: Safety Tips for RVers

If you can hear thunder, lightning is not far away

We don’t usually plan our RV trips around thunderstorms or other severe weather. If we knew we’d be spending our vacations taking cover, most likely we’d reschedule our trips. But storms occur throughout the year in just about every place in the world, so they are a fact we simply have to accept. And accepting the reality of storms should prompt us to prepare for how storms can affect us when we’re traveling in our RVs.

The most basic preparation is an emergency preparedness kit that includes a first aid kit. Make sure you check it regularly to ensure that any used supplies have been replaced and that nothing has passed its expiration date.

Heat lightning

The term heat lightning is commonly used to describe lightning from a distant thunderstorm just too far away to see the actual cloud-to-ground flash or to hear the accompanying thunder. While many people incorrectly think that heat lightning is a specific type of lightning, it is simply the light produced by a distant thunderstorm.

An old term to describe summertime storms! After all, all lightning is “hot”—the typical bolt of lightning has a temperature of 50,000 degrees Fahrenheit. Ouch!

Thunderstorm facts

The definition of a severe thunderstorm is one producing hail one inch in diameter (size of a quarter) or winds of 58 mph or more.

According to the National Weather Service (NWS), “Each year across America there are on average 10,000 thunderstorms, 5,000 floods, 1,000 tornadoes, and six named hurricanes.” The NWS pointed out that weather disasters lead to about 500 deaths annually.

Every thunderstorm produces lightning.

Thunderstorms can produce high winds that can damage property.

Thunderstorms can cause flash flooding.

Lightning kills more people annually than tornadoes or hurricanes.

A thunderstorm WATCH means that conditions are right for a thunderstorm to develop in the watch area. Be ready to take cover or evacuate.

A thunderstorm WARNING means that a severe thunderstorm has been reported or detected on radar threatening danger to property or life. Take cover or evacuate if there is time and a safe escape route.

If you hear it—clear it

According to the National Weather Service (NWS), if you can hear thunder, the storm is close enough that lightning could strike your location at any moment! NWS strongly urges that “If you hear it—clear it!”

All RVers need to remember the Flash to Bang or 30/30 Lightning Rule. If a thunderstorm develops, count the seconds between the flash of lightning and the bang of the thunder to estimate the distance between you and the lightning strike. Because sound travels at about one mile in five seconds, you can determine how far away the lightning is by using this ‘flash-to-bang’ method.

It’s recommended you seek shelter if the time between the lightning flash and the sound of thunder is 30 seconds or less, or six miles away. Once you’re an inside shelter, you should not resume activities until 30 minutes after the last audible thunder.

Be alert to threatening weather © Rex Vogel, all rights reserved

Stay informed with local weather forecasts

Unless you’ve RVing in the wilderness, there will be a way to monitor the weather and learn about impending thunderstorms. Cell phones, Internet weather reports, NOAA radios, TV news, weather stations, and local warning systems are some of the ways to be aware of weather threats.

If you’re staying at an RV Park the manager may alert park guests when severe weather is approaching. But it’s advisable to enquire about storm or tornado shelters and local warning systems when registering at the campground.

More on severe weather: Tornado Safety Tips for RVers

NOAA’s NWS, WeatherBug, Weather.com, and other online weather sites can give you a three- to ten-day forecast.

Camping under trees can be hazardous in severe weather © Rex Vogel, all rights reserved

Check your RV and site for safety

Most RVers like shady sites on hot summer days. But shade usually comes from trees. Check the trees and shrubs at your site for sturdy branches or ones that might break under high wind conditions. Large branches can cause severe damage to your RV and toad/tow vehicle if not injuries to people. If you notice weak branches ask your park owner to trim them.

>>Check your site for chairs, tables, toys, BBQs, and other objects that can become projectiles in high winds. Bring them inside, tie them down, or secure them in some other way.

>>Bring your animals inside during threatening weather.

>>Get your emergency preparedness kit out.

>>Make sure your outside storage doors are closed and locked.

>>Retract any awnings and ensure they’re securely fastened.

>>Close and latch your windows.

>>If you are going to evacuate, leave early, and make sure you are not heading into the storm.

Take cover before the storm arrives

The safest place to locate during a thunderstorm—if you choose not to evacuate­—is in the basement of a sturdy building. This area will give you the greatest protection from lightning, winds, tornados, and flying objects. The next safest area is an inside room with no windows and plenty of walls between you and the storm.

More on severe weather: Hail Can Be a Killer Especially For Your RV

Like mobile homes, RVs can be blown over in high winds. They’re not the safest place to be. But if you have no alternative, stay in a hallway away from windows and cabinets that can fly open turning their contents into projectiles.

If you see lightning or hear thunder, stay inside.

Stay inside for about 30 minutes after you hear the last thunderclap.

Unplug electronics like TVs, DVDs, computers, coffee pots, and so forth. Use cell phones and battery-powered devices. A battery-powered NOAA radio would be very useful at a time like this.

Other Dangers

Both during and after a severe thunderstorm flooding may be a problem. If you are in a low area, move to higher ground. Some RV parks have a flood gauge showing five or six feet above their entry driveway.

If you are traveling and come across a flooded roadway, don’t try to drive through it. You could get washed away if the water is moving rapidly. Or, if there are downed power lines in that water, you could be electrocuted.

Lightning strikes can split trees, breaking large branches off, and start wildfires.

More on severe weather: Arrival of Summer: On Dehydration, Hurricane Season & RVs

If someone has been struck by lightning, call 911 and start CPR immediately. The American Heart Association has a “learn CPR in one minute eight seconds” course that teaches CPR well enough that anyone can deliver effective CPR in such an emergency.

Worth Pondering…

If I accept the sunshine and warmth, then I must also accept the thunder and lightning.
