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

Is Staying Cool the Hot New Thing?

As summer heats up a small but growing number of cities are getting serious about heat mitigation

Scientific studies have documented a dramatic rise in both heat-related and cold-related deaths and there’s general agreement that cities need to adopt comprehensive strategies to maintain public health. One of the studies found the number of deaths caused by high temperatures increased by 74 percent globally between 1980 and 2016. Deaths related to extreme cold increased 31 percent since 1990, another report, the first of its kind, found.

Heat-related deaths and illnesses are preventable, according to the US Centers for Disease Control and Prevention and yet more than 600 people in the US alone are killed by extreme heat every year. Last year’s extreme heat wave in the Pacific Northwest resulted in an estimated 1,400-plus deaths. In neighboring British Columbia, 619 deaths reported June 25-July 1, 2021 were deemed heat related.

But most cities are only at the planning stages or conducting small-scale pilots—if they’re addressing the issue at all. There’s broad acknowledgment that rising temperatures are making urban centers less livable but many cities lack the budget or political support to meaningfully tackle the problem.

A survey by the American Council for an Energy Efficient Economy (ACEEE) and the Global Cool Cities Alliance (GCCA) reviewed the urban heat mitigation activities of 26 cities in the U.S. and Canada—representing all of the major climate zones, geographies, and city sizes across North America. They found that heat waves along with other natural disasters and extreme weather have motivated nearly two-thirds of the cities surveyed to initiate urban heat island mitigation strategies.

The report included case studies on how several cities have responded to urban heat demonstrating the variety of strategies employed. In response to a study that found that Houston’s roofs and pavements can reach 160 degrees F, the city now requires most flat roofs in the city to be reflective. After an extreme heat wave in 2008, Cincinnati lost much of its urban canopy and instituted an aggressive forestry plan. Washington D.C. has instituted a wide suite of programs such as Green Alleys which helps residents manage excess stormwater by replacing pavement with grass and trees and requiring reflective roofs on all new buildings.

Three major U.S. metro areas—Phoenix, Los Angeles, and Miami/Dade County—have established “Chief Heat Officers.”

Cities have been gearing up for this summer’s heat trying in particular to use cooling methods other than air conditioning. They’re installing cooling and misting centers and hydration stations and planting trees for extra shade.

They’re experimenting with high-tech solutions like sealants and reflective coatings for sidewalks, streets, and rooftops.

A growing number of startups are crowding into the market for products to counter “urban heat islands” with experimental (and proven) technologies aimed at absorbing or reflecting surface heat on roads, sidewalks, buildings, and other structures.

The big picture: Cities have been warming at twice the global average because of the “urban heat island” effect whereby buildings and pavement trap heat that might have otherwise been diffused by foliage.

Low-income people tend to suffer the most since they’re more likely to lack A/C, work outdoors, and live near industrial facilities.

Phoenix—one of the hottest U.S. cities—has been proactive in tackling the problem. The temperature climbs above the 100-degree mark daily from the end of May through the middle of September. These blistering hot days are followed up by warm nights with the low temperature sometimes failing to drop below 90.

More on severe weather: Heat Alert: The Hidden Symptoms of Extreme Heat

Its “Cool Pavement Program” which involved painting a gray coating on streets reduced roadway temperatures by 10.5 to 12 degrees, reports Scientific American. Cool pavement is a water-based asphalt treatment that is applied on top of the existing asphalt pavement. It’s made with asphalt, water, an emulsifying agent (soap), mineral fillers, polymers, and recycled materials. It contains no harmful chemicals and is compatible with traditional asphalt.

The city aims to build 100 “cool corridors” by 2030 “in shade-starved zones with high pedestrian traffic,” the Arizona Republic reports.

Cool corridors are approximately one-mile-long walkways, pathways, or trails, adjacent and parallel to city streets that are designed to serve residents who walk, bike, and use transit. Collector or local streets and various pathways also could serve as cool corridors that provide important linkages with cool corridor arterials

Without more trees and other urban cooling features, the Phoenix area stands to lose hundreds more lives and billions of dollars in lost economic production each year by mid-century if the region doesn’t adopt widespread tree planting and cool roof installation, a Nature Conservancy study concluded last year.

“Heat is a really significant issue,” said Anna Bettis who directs TNC’s Healthy Cities Program in Arizona. “It’s the leading weather-related cause of death and the highest rates are in Arizona.”

But, Bettis said, “We do know that bringing nature into the city can help.” That means lots of desert-adapted trees.

In 2020, according to Maricopa County, 323 people died of heat-related causes. The county has confirmed 252 heat deaths this year and is investigating another 86.

Among smaller cities, Chelsea, Massachusetts, a low-income neighbor of Boston has a noteworthy pilot involving a single city block. The Cool Block project is loading the area with pretty much every heat-fighting tool in use around the country,” according to WBUR. There are 47 new elm, crabapple, cherry, and hawthorn trees. Sidewalks are being ripped up to add planters, porous pavers, or white concrete. Dark asphalt will be replaced with gray.

As cities race to amp up their heat mitigation efforts, some are replacing bare-bones cooling centers with full-service “climate resilience hubs”—offering everything from comfy air conditioning and phone charging to social services and emergency training.

While “resilience hubs” are meant for everyone and all kinds of climate disasters, they’re particularly aimed at low-income residents who tend to suffer disproportionately as temperatures rise.

Miami-Dade County is at the forefront with its mobile “resilience pod” made from a 40-foot shipping container. It debuted two years ago and offers people a chilled, solar-powered place to gather with Wi-Fi, phone charging, and other solutions including fruit trees for people to plant.

10 of the Hottest Cities in America

It’s summer. It’s hot. That’s what summers do.

Some of the most populated cities across the United States are also some of the hottest places to be during the summer with temperatures regularly climbing above 100 degrees F.

Many cities don’t come close to the extreme heat experienced in Death Valley, California; however, the population in Death Valley is just a small fraction of that of many towns across the country.

Cities are warming at twice the global average because buildings and pavement absorb and trap so much heat. Phoenix, Los Angeles, and Miami have named chief heat officers to find ways to prevent the often deadly impacts of extreme heat. 

From the shores of the Atlantic Ocean to the deserts of the Southwest, here are 10 of the hottest cities across the United States with a population of over 250,000.

Desert Botanical Gardens, Phoenix © Rex Vogel, all rights reserved

1. Phoenix, Arizona

Phoenix is home to over 1.6 million people and regularly experiences some of the highest temperatures of any city across the country. The temperature climbs above the 100-degree mark daily from the end of May through the middle of September. These blistering hot days are followed up by warm nights with the low temperature sometimes failing to drop below 90.

Phoenix recorded its hottest summer ever in 2020 with 50 days at or above 110 degrees and a record 28 nights when the temperature never dropped below 90 degrees.

Heat is killing about 300 people per year in Phoenix. 

Phoenix is trying to beat the heat by turning its black asphalt streets gray. A special sealant reflects rather than absorbs the hot desert sun.

America’s hottest city is working to avoid getting even hotter—starting with its streets. As heat waves across the country continue, Phoenix is covering black asphalt roads with a gray sealant that reflects the sun rather than absorbing heat. Mayor Kate Gallego says the sealant which has so far been used on 73 miles of city streets reduces the temperature of asphalt by 10 to 12 degrees.

2. Las Vegas, Nevada

Las Vegas is a popular tourist destination in the southwestern United States but visitors may want to plan to visit areas with air conditioning during the summer months. The city averages over 70 days a year with temperatures in the triple digits and has reached its all-time record high of 117 on several occasions.

People traveling to popular tourist destinations nearby such as Lake Mead National Recreation, Red Rock Canyon, or the Hoover Dam should also expect to encounter extreme heat and should take the proper precautions to stay safe.

3. Tucson, Arizona

Tucson sits on the edge of the Sonoran Desert and is nearly as hot as Phoenix located 100 miles to the northwest. One of Tucson’s hottest summers in recent years occurred in 2013 when the city climbed into the 100s for 39 consecutive days including all of June.

Monsoonal thunderstorms can provide temporary breaks in the extreme summer heat but they can also kick up dust storms called haboobs that can greatly reduce visibility and cause dangerous travel conditions.

4. Riverside, California

While the cool waters of the Pacific Ocean help to limit temperatures along coastal areas of Southern California areas father inland can experience much hotter conditions. Riverside, approximately 50 miles east of downtown Los Angeles has recorded triple-digit heat every month from April through October with an all-time high of 118. This is higher than the record in Las Vegas and just a few degrees shy of the record high in Phoenix.

5. San Antonio, Texas

San Antonio is home to more than 1.5 million people and experiences long stretch with temperatures in the 90s during the height of summer. On average, the city reaches the 90-degree mark more than 110 days out of the year as well as several days in the low 100s. August is the hottest month of the year in San Antonio with an average high temperature near 97, one of the highest averages across the entire country among major cities.

6. Miami, Florida

Although the mercury in southern Florida doesn’t climb as high as it does in the southwestern United States during the summer, Miami’s proximity to the tropics can make it feel oppressively hot, especially for those not accustomed to the high humidity levels. Miami has never recorded a temperature of 100 but the strong summer sun paired with the humidity can send the AccuWeather RealFeel temperature over 110 on the hottest afternoons of the year.

Miami is also one of the warmest cities in the country during the winter with afternoon temperatures often climbing near 80.

7. Houston, Texas

Tropical moisture from the Gulf of Mexico has a strong influence on the weather pattern along the coast of Texas including in Houston, the state’s most populated city with over 2 million people. The humidity helps to boost the AccuWeather RealFeel temperature above 100 daily. Moisture from the Gulf also helps to fuel rain and thunderstorms making Houston the wettest among the county’s hottest cities averaging over 100 days a year with rain.

8. Fresno, California

Outside of the Mojave Desert and the Colorado Desert, the Central Valley is California’s hottest region with temperatures often reaching the triple digits. This includes Fresno, home to over half a million people. In 2018, the city experienced 30 consecutive days with a temperature at or above the 100-degree mark, the longest stretch in the city’s history.

9. Dallas, Texas

Located farther inland from the Gulf of Mexico than Houston or San Antonio, Dallas can experience some of the hottest weather of all of Texas’ major cities. Being farther away from the source of tropical moisture allows temperatures to be slightly higher than near the coast with daily highs in the mid- to upper 90s from the end of June into early September.

Although the summer heat can be more intense in Dallas than Houston or San Antonio, the city experiences cooler winters with temperatures frequently dipping below freezing.

10. Orlando, Florida

One of Florida’s hottest cities is also one of its most popular tourist spots with a record-setting 72 million people visiting in 2017. Unlike Miami, temperatures in Orlando can occasionally reach the 100-degree mark with an all-time record high of 103. Overnight temperatures also remain warm as they rarely dip below 60 from June through September.

Orlando also remains warm throughout the winter with afternoon highs in the 70s and overnight lows that rarely drop below 30.

Heat Alert: The Hidden Symptoms of Extreme Heat

Heat stroke is rare but there are other symptoms people often are not aware of

The consequences of extreme heat can be severe: last year, more than 600 people died during the heat dome in British Columbia and, in 2018, up to 70 deaths in Quebec were linked to a heat wave there. 

In Europe, more than 1,100 people have died from the heat in Spain and Portugal in recent weeks. The UK recorded its hottest-ever temperature last week (July 19, 2022) with a reading of 40.3 degrees Celsius in eastern England. What’s that in Fahrenheit? Remember what your sixth-grade science teacher explained: Multiply by 1.8 then add 32. That comes out to 104.5 degrees Fahrenheit.

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

Not that many folks are asking. Only the US, Belize, Palau, the Bahamas, and the Cayman Islands use Fahrenheit as their official temperature scale.

More than 100 million Americans are under a heat-related alert and at risk of heat-related illnesses, at the time of writing. Temperatures across much of the country are in the 90s to 100 degrees or higher. 

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

Heat Advisories and Excessive Heat Warnings are in effect from Texas through the southern Plains and lower Mississippi and Ohio valleys where temperatures are expected to reach triple-digits in many locations. The Excessive Heat Warnings include major cities in Texas such as Dallas, Lufkin, San Angelo, Houston, and San Antonio. Outside of Texas, the warning includes Oklahoma City, Little Rock, Arkansas, and Monroe, Louisiana. Heat Advisories are in effect elsewhere from New Orleans north to Birmingham and Huntsville in Alabama, Nashville, Tennessee, and Paducah, Kentucky.

You can die from this kind of heat if you’re not careful, especially if you work or recreate outdoors.

A man who was hiking on an unmarked trail in southwestern South Dakota that was featured in a social media challenge died when he and another hiker ran out of water. The Pennington County Sheriff’s Office said 22-year-old Maxwell Right of St. Louis was hiking in Badlands National Park Wednesday (July 20, 2022) when he collapsed and died of suspected dehydration and exposure.

The National Weather Service (NWS) has issued an Excessive Heat Warning for portions of Arizona as temperatures in the Phoenix area could reach 116°F. The counties included in the warning are La Paz, Maricopa, Mohave, Pinal, Pima, Yavapai, and Yuma.

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

What temperature threshold triggers a heat warning varies depending on your location but the symptoms of heat-related illnesses remain the same. The thresholds that trigger Excessive Heat Watches, Excessive Heat Warnings, and Heat Advisories are not clear-cut, however.

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

Since every region of the United States and Canada experiences a different climate, people become accustomed to the climate of the region in which they live. This means what is hot to a longtime resident of Maine or northern British Columbia might not be hot to someone who has spent many years in Florida or Texas.

In general, locations farther north don’t have to be as hot for heat alerts to be issued by the NWS because extreme heat is less frequent there. Areas farther south are more accustomed to hot, humid weather, so a higher threshold must be met before watches, warnings or advisories are posted. If this wasn’t the case, parts of the South would be under a Heat Advisory nearly every day in the summer.

It’s not (just) the heat, it’s the humidity

The point at which a combination of heat and humidity becomes especially dangerous or even deadly is explained by scientists as “wet-bulb temperature”— the lowest temperature at which an object can cool down due to evaporating moisture.

Imagine a thermometer wrapped in a wet cloth: the water will keep evaporating from the cloth up until a certain level of humidity when the air contains too much moisture for evaporation to continue. Because of the evaporative effect, the temperature of the thermometer will be lower than the air around it—that is, until evaporation stops.

Heat-related illnesses arise when an individual is exposed to environmental heat and their own body is not able to accommodate or acclimatize quickly. These symptoms are potentially life-threatening and should be taken seriously when they happen. But it’s not just about heat stroke.

There’s a spectrum of heat-related illness symptoms.

Heat-related illnesses can range from mild, requiring cooling and rehydration, to severe—requiring emergency medical treatment. 

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

Yellow Zone: Mild heat-related illness

Heat edema occurs when blood vessels dilate and blood accumulates in the hands and feet due to gravity, says the U.S. Centers for Disease Control and Prevention (CDC). People with diabetes, cirrhosis, and heart conditions are at a higher risk. The treatment is to elevate the swollen area to drain it.

Watch for: Swollen ankles, feet, or hands.

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

Heat rashes occur when sweat glands get blocked or inflamed. The CDC recommends keeping the rash area dry and applying powder to increase comfort.  Heat rashes commonly occur in sweaty areas like your groin, your neck, or your armpits.

Watch for: Rashes on the face, chest, arms, and groin.

Heat cramps happen when the body loses salt and water and is treated by replenishing carbohydrates and electrolytes with a snack, water, or sports drink.

Watch for: Cramps in abdomen, arms, and calves.

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

Orange Zone: Moderate to severe heat-related illness

Heat syncope when someone feels light-headed after standing up is treated with rest and relief from the heat, sitting or lying down in a cool place, and slowly drinking water, clear juice, or a sports drink. 

Watch for: Fainting (short duration), light-headiness from standing, sitting, or lying position.

Heat exhaustion happens when you experience an excessive loss of water and salt usually through sweating. It is treated by cooling down with cold packs, washing the head, face, and neck with cold water, and frequently sipping cool water. 

Watch for: Weakness, dizziness, headache, fatigue, muscle cramps, vomiting. 

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

Red Zone: Severe heat-related illness 

Heat strokes occur when the body’s cooling mechanism fails so you stop sweating and internal temperature heats up. Emergency medical care is required at this point. It helps to cool down with cold water, an ice bath, and soaking clothes with cool water. 

Watch for: Confusion, hallucinations, less sweat, rapid breathing, increased heart rate, throbbing headache, loss of consciousness, and altered mental state.

Staying Hydrated – Staying Healthy

When the temperatures rise, getting enough to drink is important regardless of the activity. Keeping the body hydrated helps the heart more easily pump blood through the blood vessels to the muscles. And, it helps the muscles work efficiently.

If you’re well hydrated, your heart doesn’t have to work as hard,” said John Batson, M.D, a sports medicine physician with Lowcountry Spine & Sport in Hilton Head Island, South Carolina.

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

Dehydration can be a serious condition that can lead to the above heat-related illnesses—ranging from swollen feet or a headache to life-threatening illnesses such as heat stroke. But staying hydrated is a daily necessity no matter what the thermometer says.

How much water should you drink each day? It’s a simple question with no easy answer.

Studies have produced varying recommendations over the years. But your individual water needs depend on many factors including your health, exercise intensity and duration, and climatic conditions.

No single formula fits everyone. But knowing more about your body’s need for fluids will help you estimate how much water to drink each day.

Extreme heat can have severe consequences © Rex Vogel, all rights reserved

For most people, water is the best thing to drink to stay hydrated. Sources of water also include foods such fruits and vegetables which contain a high percentage of water. Sports drinks with electrolytes may be useful for people doing high intensity, vigorous exercise in very hot weather though they tend to be high in added sugars and calories.

It’s also best to avoid drinks containing caffeine which acts as a diuretic and causes you to lose more fluids.

Excessive Heat Warnings: Safety Tips for RVers

Look out for these heat exhaustion symptoms while camping

Dangerous temperatures exceeding 105 degrees Fahrenheit in select areas of the Southeast and Southwest have prompted excessive heat warnings. The weather conditions pose a threat to young children, older adults, and anyone who doesn’t take the right safety precautions before and during the heat wave.

Last year, 43 Texas State Parks reported 102 heat-related illnesses in humans and pets. Since January 1, 54 heat-related incidents have already been reported, compared to 34 reported by this time last year, according to a news release from the department in late June.

Heat-related incidents can be prevented with a few measures to ensure that both you and your family can safely get through this heat wave.

Heat Exhaustion

Heat exhaustion is a very real threat to anyone who spends a lot of time in the sun. Even though it’s not always obvious from the get-go, several heat exhaustion symptoms can let you know there’s a problem. 

As someone who has experienced heat exhaustion, it’s not a fun time! It interrupted my whole day and left me feeling weak, nauseous, and shaky. 

Below, I’ll provide a comprehensive guide to heat exhaustion including its prevention, symptoms, treatment options, and the difference between heat exhaustion and heat stroke.

Prevention

With temperatures soaring into the triple digits, the Texas Parks and Wildlife Department shared their suggestions for staying safe in the outdoors. Here are their top six heat hacks:

>> Hydrate: It’s important to drink at least 16 ounces of water every hour in the heat to replenish your body and prevent dehydration. Don’t forget to bring enough for your four-legged family members too.

>> Block the Rays: Apply a generous amount of sunscreen or sunblock before heading outdoors. Be sure to reapply every couple of hours and after swimming or sweating.

>> Dress Smart: Wear light, loose-fitting, breathable clothing; a wide-brimmed hat, correct shoes, sunscreen, and wet bandanas to keep you cool while in the sun. For pets, protect paws against blistering by hitting the trails during cooler times of the day when the ground isn’t hot or by putting booties on pets to help shield paws from the hot ground. Touch the pavement or ground with the back of your hand. If you cannot hold it there for five seconds, the surface is too hot for your dog’s paws.

>> Stay Salty: Food helps keep up energy and replace salt lost from sweating. Eating snacks such as jerky, granola, trail mix, tuna, and dried fruit is a fantastic way to nourish your body while on the trails.

>> Buddy System: Two brains are better than one. It’s beneficial to have someone with you in hot conditions so you can look after each other on the trail. With high temperatures, heat-related illnesses are common, and having a friend around to help recognize the early symptoms can save you from getting sick.

>> Plan Ahead: Study the map and have it with you, avoid relying on your phone for maps since service may be unavailable in back-country areas. Average hikers move at 2 miles per hour, so allow yourself plenty of time to avoid hiking in the heat of the day. Make sure to rest in a cool or shaded area to recover from the heat if necessary. It is also a good idea to let someone know your plan before you hit the trails and what time you should be back. That way, if you become lost, people know where to look.

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. This can then lead to overheating, reports WebMD. You can experience heat exhaustion on any warm day but the risk increases exponentially if the temperature is 90 degrees Fahrenheit or more. If the heat and humidity are high, limit strenuous activity and try to stay indoors during the hottest parts of the day.

Know if you are in a high-risk group. Heat exhaustion can affect anyone but the most vulnerable are those who are young and old: Children younger than 5 and adults older than 65 need to take extra precautions to avoid heat exhaustion.

If you do plan to spend time outdoors during a particularly hot or humid day, you can form good habits to protect yourself. First of all, hydrate! Drink plenty of water throughout the day, even if you’re not feeling thirsty. 

Wear appropriate clothing and sun protection. Wear loose, light-colored clothing that is breathable. A breathable wide-brimmed hat will help you stay cool. Apply sunscreen frequently as well. If you have severe sunburn, you’re more likely to develop heat exhaustion because your body is warmer than usual according to Health Line.

Finally, NEVER leave children or pets in cars on hot days. This is common sense for most people but a reminder is still needed. Even adults can become overheated if they spend too much time in this environment!

Symptoms

First things first, you need to know the warning signs for heat exhaustion. This usually builds up over time and doesn’t hit you all at once. Some people might experience every symptom while others only have a few.

According to the Mayo Clinic the heat exhaustion symptoms and warning signs to watch for include:

  • Heavy sweating
  • Cool, damp skin
  • Dizziness
  • Fatigue
  • Light-headedness
  • Weak, rapid pulse
  • Muscle cramps
  • Nausea
  • Vomiting
  • Headache
  • Low blood pressure (especially when standing up quickly)
  • Swollen feet or hands
  • Shallow breathing
  • Dark urine
  • Pale skin
  • Fainting
  • Confusion

If you or someone around you is experiencing these heat exhaustion symptoms, it’s important to treat them immediately. Heat exhaustion can turn into heat stroke if it isn’t promptly dealt with.

Treatment options

Once heat exhaustion has set in, there are several things you can do to treat yourself or others according to the Cleveland Clinic. It’s best if you can get someone to help you because a person who is affected shouldn’t be moving around too much. 

First of all, heat exhaustion occurs when your body gets too hot and cannot cool itself down. This is especially common in areas with high heat and high humidity (because your sweat cannot evaporate and cool you down). 

Your priority needs to be lowering your body temperature. If possible, go indoors and find a cool room and lie down. Otherwise, look for a shady area where you can get out of the sun. Don’t exert yourself in this condition.

You need to hydrate. Heat exhaustion commonly occurs when someone is dehydrated because they don’t have enough fluids to produce cooling sweat. Drink cool water or sports drinks to replenish fluids and electrolytes. Don’t gulp it down, but take small sips so you can slowly adjust. If you drink too much too soon, you’ll cause more harm than good. Avoid soda and alcohol during this time. 

Finally, try to cool down with exterior methods. You can use cold washcloths, air conditioning, fans, or a cool bath/shower to lower your body temperature. If the affected person is wearing tight, restrictive clothing, that should also be removed.

Try all of the methods above for about one hour. If the heat exhaustion symptoms don’t improve during this period, it’s time to seek medical attention.

Heat stroke

Heat exhaustion isn’t fun to deal with but most people who receive proper treatment make a full recovery within a day or two. However, if the exhaustion is left untreated, it can rapidly change into heat stroke. 

This is a serious medical emergency that can end in death. A heat stroke occurs when your body temperature reaches 104 degrees Fahrenheit or higher. It can cause brain damage and can be life-threatening for most people reports the Mayo Clinic.

According to Health Line, symptoms of heat stroke include:

  • High fever (104 or higher)
  • Flushed, red skin
  • Headache
  • Delirium
  • Rapid heartbeat
  • Seizures
  • Coma

If heat stroke has begun to set in, you need to seek medical help immediately. While you wait for them to arrive, do everything possible to lower the body temperature of the affected person. Immerse them in a cold bath, mist the skin with cool water, or apply ice packs to high blood flow areas (wrists, neck, groin, armpits). Get them out of the sun and keep them still until help arrives, states the Mayo Clinic.

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.

Dress Smart

Wear light, loose-fitting, breathable clothing; a wide-brimmed hat (I prefer a Tilley), good walking shoes, sunscreen, and wet bandanas to keep you cool while in the sun. For pets, protect paws against blistering by hitting the trails during cooler times of the day when the ground isn’t hot or by putting booties on pets to help shield paws from the hot ground. Touch the pavement or ground with the back of your hand. If you cannot hold it there for five seconds, the surface is too hot for your dog’s paws.

Stay Salty

Food helps keep up energy and replace salt lost from sweating. Eating snacks such as jerky, granola, trail mix, pretzels, tuna, and dried fruit is a fantastic way to nourish your body while on the trails.

Heat and Dogs

Every year, dogs die after hiking with their owners in parks. Your dog will follow wherever you lead. But remember, your pet is wearing a fur coat and isn’t wearing shoes. Remember the five-second rule. Place the back of your hand on the pavement or ground. If you cannot hold it there for five seconds, the surface is too hot for your dog’s paws.
