An RV is not a safe structure in severe weather. This is the fact that every RVer needs to internalize: your rig offers minimal protection from tornado-force winds, lightning, or flash flooding. Knowing when to stay, when to leave, and where to go for real shelter can save your life.
Tornadoes: The Most Dangerous Threat
A tornado will destroy or overturn a recreational vehicle. There is no arguing with this physics. If a tornado watch or warning is issued for your area, leave the RV and find a substantial structure immediately.
What to do when a tornado warning is issued:
- Leave the RV immediately — do not wait to see if the storm passes
- Get to the campground's permanent restroom/shower building or any nearby solid-constructed building
- If no building is available, get to a low-lying area away from trees and lie flat in a ditch or culvert
- A vehicle is slightly safer than an RV — if no building is available, a vehicle with seatbelts below the level of surrounding terrain is the emergency fallback
Planning ahead: When you check in to any campground in tornado-prone regions (Kansas, Oklahoma, Nebraska, Texas, Missouri, Iowa), ask the staff where to go in a tornado. Many campgrounds have designated shelter buildings or bathhouses built to serve this purpose.
Technology: Download NOAA's official weather app and enable severe weather alerts. Wireless Emergency Alerts (WEA) will sound your phone even when it's on silent — don't disable them.
Lightning
An RV provides better lightning protection than a tent but is not completely safe. The metal frame of the RV provides some Faraday cage effect, but the chassis and tires are not proper grounding systems. During an active lightning storm:
- Stay inside the RV and away from windows
- Avoid contact with metal surfaces, plumbing, and the stove
- Don't use a corded phone (if you still have one) or plug-in electronics
- Do not shelter under trees — a lightning strike to a tree can conduct to the ground and reach you
- If outside when lightning begins, get into the RV or a vehicle immediately
Flash Floods
Flash floods kill more people annually in the US than tornadoes or hurricanes. Many campgrounds are located near rivers and streams — specifically because those are attractive locations. The danger comes from:
- Upstream rain you can't see: A flash flood can arrive at your campsite from a storm that hit 20 miles away, in terrain you couldn't see from your location. Clear skies at your campsite don't mean safety.
- Speed of rise: Flash floods can raise water 10–20 feet in minutes. Once you see water rising rapidly, you have less time than you think.
Prevention: Before setting up camp near any water feature, check the elevation difference between your site and the waterway. NWS issues flash flood watches — these should prompt moving to higher ground proactively. Don't wait for the warning, which often means the flood is already happening.
If flooding begins: Move to high ground immediately. Do not try to drive the RV through flowing water — 6 inches of fast-moving water can knock a person down, and 12–18 inches can carry away an RV.
High Winds
High winds (sustained 40+ mph or gusts above 55 mph) present unique challenges for RVs:
- Retract your awnings: Any awning left out in wind above 20 mph risks damage or being torn off. If you see weather approaching, get the awning in immediately.
- Stabilizer jacks down: Lowering stabilizer jacks helps prevent rocking in wind but does not prevent a rig from being lifted or tipped in truly extreme conditions.
- Park perpendicular to expected wind direction: Minimizes the side profile exposed to wind. Not always possible, but when you have a choice, it matters.
- Secure outdoor items: Chairs, rugs, outdoor kitchen equipment, and decorations become projectiles in high wind. Store everything before storms arrive.
- High-profile driving: Tall rigs (particularly Class A motorhomes and fifth wheels over 13 ft) are extremely susceptible to crosswind on highways. NOAA and state DOTs issue high wind advisories for certain highways — check before driving.
Before Every Trip: Check Weather
This sounds obvious but many RVers don't do it systematically. Before departing each day, check:
- Weather for your route (not just origin and destination)
- Any active NWS watches or warnings for counties you'll pass through
- Campground weather at your destination for the next 48 hours
