Severe Storms and Tornadoes
Severe thunderstorms can produce damaging wind, large hail, flash flooding, and tornadoes. RVs, travel trailers, fifth wheels, and mobile homes are not safe tornado shelters.
Before you drive or camp
- Have at least two ways to receive warnings, such as Wireless Emergency Alerts, a trusted weather app, NOAA Weather Radio, local TV or radio, campground alerts, or National Weather Service products.
- Know the county you are in. Many warnings are issued by county, and that can matter when you are away from home.
- Ask the campground, fairground, park, Harvest Hosts location, or rental operator where to shelter before storms arrive.
- Identify a sturdy building, bathhouse, storm shelter, or other substantial structure. Do not assume a building will be unlocked.
- Bring pets, medication, shoes, keys, phones, flashlights, and basic essentials quickly if you need to leave the RV.
If you are already on the road
- Do not drive toward a warned storm if you have a practical way to avoid it or wait it out.
- If a Tornado Warning is issued for your location, get to a sturdy building immediately if one is available.
- Avoid sheltering under highway overpasses. They can increase wind exposure and create traffic hazards.
- If no building is available and a tornado is imminent, you face bad options. Get as low as possible, protect your head, and avoid flood-prone ditches.
- If you stay in a vehicle as a last resort, keep your seat belt on and your head low and covered. This is a last-resort choice, not a preferred plan.
When to stop or change plans
If a severe thunderstorm or tornado warning is issued for your location, stop treating the RV as shelter. Move to a substantial building if available. If a higher-end severe-weather outbreak is forecast along your route, delay, reroute, or stay close to a shelter.
High Wind and Dust Storms
Wind can make an RV hard to control, especially in crosswinds, exposed terrain, mountain gaps, bridges, and around trucks. In desert areas, high winds can also create sudden dust storms and near-zero visibility.
Before you drive or camp
- Check wind forecasts before departure, especially for exposed highways, mountain passes, deserts, bridges, and open plains.
- Retract awnings and secure outdoor gear before wind increases.
- At camp, reduce your profile when possible: face into the wind, pull in slide-outs, fill fresh-water tanks if practical, and hitch up a trailer or fifth wheel if needed for added stability.
- Look for trees, limbs, loose objects, signs, and debris that could fall on or blow into the RV.
- Know whether the strongest winds are expected during your planned driving window. An earlier departure or a one-day delay may be the safer choice.
If you are already on the road
- Slow down. Speed increases the effect of wind on control.
- Keep both hands on the wheel and leave extra space around semis, buses, and other high-profile vehicles.
- Expect sudden pushes when passing or being passed by large vehicles.
- If blowing dust sharply reduces visibility, pull as far off the roadway as safely possible, stop, keep your seatbelt on, take your foot off the brake, and turn lights off so other drivers do not try to follow you.
- If the drive is becoming stressful or control margins feel thin, get off the road before conditions worsen.
When to stop or change plans
There is no universal RV wind limit. Rig size, weight, hitch setup, road exposure, traffic, wind direction, and driver experience all matter. As a practical rule, strong crosswinds or gusts that make lane control difficult are enough reason to stop.
Flooding and Heavy Rain
Flooding can develop quickly, especially near low-water crossings, dry washes, small streams, burn scars, steep terrain, and urban drainage areas. Flooded roads are dangerous because depth and road condition are hard to judge.
Before you drive or camp
- Check for Flood Watches, Flash Flood Warnings, and excessive rainfall risk before choosing a route or campsite.
- Do not camp in a dry wash, near a small stream or river, or in a low spot if heavy rain is possible nearby or upstream.
- Check your vertical elevation above the water, not just how far away the stream or river may be. Do not bet your life on someone coming to tell you to move.
- Ask campgrounds about local flood-prone roads and low-water crossings.
- Know your route out of the campground before heavy rain begins.
- At night, be even more conservative. Water depth and road washouts are much harder to see.
If you are already on the road
- Never drive around barricades.
- Do not drive through flooded roads. Turn around and find another route.
- Remember that the road may be washed out under the water.
- If water is rising around your vehicle and it is safe to get out, abandon the vehicle and move to higher ground.
- Avoid walking through flood water. Moving water can knock people down and hide debris, holes, or washed-out pavement.
When to stop or change plans
If a road is flooded, stop and turn around. If heavy rain or flash flooding is expected along your route, delay or reroute before you reach low-water crossings or steep terrain.
Hurricanes and Tropical Storms
Tropical storms and hurricanes usually provide more warning time than tornadoes. That makes the RV’s greatest advantage - its wheels - very important. Leave early while routes, fuel, campsites, and options are still available.
Before you drive or camp
- Avoid coastal campgrounds, barrier islands, bayous, rivers connected to the ocean, and other storm-surge locations when tropical threats are possible.
- Monitor National Hurricane Center forecasts, local emergency management, campground instructions, and evacuation orders.
- Decide early. Waiting reduces your route, fuel, and campsite options.
- Move inland and away from storm surge and freshwater flooding risk.
- If a campground closes or local officials advise evacuation, leave.
If you are already on the road
- Do not attempt to drive through tropical-storm or hurricane conditions in an RV.
- Avoid flooded roads and downed power lines after the storm.
- Expect fuel shortages, power outages, closed roads, debris, and limited dump/water services after landfall.
- Remember that landfalling tropical systems can also produce tornadoes.
When to stop or change plans
If hurricane conditions are forecast near your campsite or route, do not plan to ride it out in an RV. Leave early, especially from coastal or flood-prone locations.
Heat
Heat affects travelers, pets, batteries, tires, generators, air conditioners, refrigerators, and campground power systems. An RV can become dangerously hot quickly if cooling fails.
Before you drive or camp
- Check HeatRisk, heat advisories, excessive heat warnings, and overnight low temperatures.
- Plan around campground power reliability, generator rules, shade, and whether your air conditioning can keep up.
- Keep extra water available for people and pets.
- Do not leave children, vulnerable adults, or pets in a vehicle or RV without reliable cooling and monitoring.
- Consider shifting travel to morning hours when afternoon heat is dangerous.
If you are already on the road
- Watch for signs of heat illness: dizziness, confusion, heavy sweating, weakness, nausea, or hot dry skin.
- Use rest stops and shaded breaks. Avoid strenuous outside work during peak heat.
- Check tire pressures and do not overload the RV.
- If the RV air conditioning fails during dangerous heat, treat it as a safety issue, not just a comfort issue.
When to stop or change plans
If heat is extreme and you cannot ensure reliable cooling for people or pets, change plans, move to a cooler location, or use a hotel or other air-conditioned shelter.
Winter Weather
Snow, ice, freezing rain, wind chill, and mountain pass conditions can create travel delays, closures, slippery roads, and serious cold-weather risks for RV systems.
Before you drive or camp
- Check winter weather watches, warnings, advisories, road conditions, and pass forecasts before departure.
- Know whether your RV is winterized or capable of operating in subfreezing conditions.
- Carry warm clothing, food, water, medication, blankets, traction aids, and enough fuel to wait out delays.
- Plan shorter driving days and avoid arriving after dark in winter conditions.
- Confirm campground access, hookups, water availability, and road plowing.
If you are already on the road
- Slow down and increase following distance on wet, snowy, or icy roads.
- Avoid steep grades, exposed passes, and untreated roads if snow or ice is expected.
- Do not assume a heavy RV or tow vehicle can stop quickly on ice.
- If conditions deteriorate, stop before you are committed to a pass, grade, or remote road.
When to stop or change plans
If snow, ice, or freezing rain is expected along your route, especially over mountain passes or after dark, delaying is often the simplest and safest plan.
Wildfire, Smoke, and Low Visibility
Wildfires can affect RV travel directly through road closures, evacuations, and fast-changing fire behavior, and indirectly through smoke, poor air quality, falling ash, fog, heavy rain, snow, or blowing dust that reduces visibility.
Before you drive or camp
- Check for active fires, evacuation areas, road closures, smoke forecasts, air quality information, and local advisories before driving into or camping near fire-prone areas.
- Use more than one information source. Wildfire conditions can change quickly, and official alerts, local emergency management, campground staff, road agencies, and wildfire apps may each provide useful pieces of the picture.
- Know your exit routes before you set up camp. Avoid camping where there is only one narrow road in or out if fire weather is elevated.
- Do not assume a campground, forest road, or scenic route will remain open if a nearby fire grows or winds shift.
- If anyone in your group is sensitive to smoke, has asthma, COPD, heart disease, or other respiratory concerns, be more conservative about driving or camping in smoky areas.
If you are already on the road
- Do not drive toward visible flames, heavy smoke columns, evacuation traffic, or closed roads.
- If authorities issue an evacuation order or campground staff tell you to leave, leave early. An RV is not the vehicle you want to maneuver through last-minute evacuation traffic.
- If smoke, fog, heavy rain, snow, or dust sharply reduces visibility, slow down and increase following distance.
- Use headlights appropriately, but avoid high beams in fog, heavy snow, or dense dust.
- If visibility drops suddenly, pull well off the travel lanes when it is safe to do so. In dust storms, stop away from the roadway, keep your seat belt on, take your foot off the brake, and turn lights off.
When to stop or change plans
If a wildfire is close enough to threaten your route, campground, or exit road, leave early or choose another destination. If visibility is too low to stop safely for hazards ahead, you are beyond a safe driving margin. Pull off safely and wait for conditions to improve.
Lightning
Lightning can strike miles from a thunderstorm. Campgrounds, open fields, beaches, lakes, and exposed ridges are poor places to remain outside during nearby thunder.
Before you drive or camp
- Check thunderstorm forecasts before hiking, biking, boating, or setting up outside.
- Know where you can get inside quickly: a substantial building or hard-topped vehicle.
- Plan outdoor activities earlier in the day when thunderstorms are less likely, especially in the mountains.
- Secure awnings, chairs, and outdoor equipment before storms arrive.
If you are already on the road
- If thunder is close enough to hear, lightning is close enough to be a threat.
- Get out of open areas, off beaches, away from isolated trees, and away from metal fences or tall objects.
- Avoid touching plugged-in electronics, plumbing, and metal fixtures during close lightning if you are inside the RV.
- Wait at least 30 minutes after the last thunder before resuming outdoor activity.
When to stop or change plans
Stop outdoor activity when thunder is heard or lightning is seen. Move inside a substantial building or hard-topped vehicle until the storm has passed.
