What to Do During a Flash Flood Warning: Safety Tips and Best Practices

A flash flood warning means flooding is either imminent or already underway in your area. These unpredictable weather events can happen with little warning and pose a serious risk to life and property. Understanding what a flash flood warning entails—and how to respond—can make all the difference when minutes count.

What Is a Flash Flood Warning?

A flash flood warning is issued when rapid, life-threatening flooding is expected or happening now. The National Weather Service (NWS) releases these warnings to alert the public to take immediate action. Flash floods often occur after intense rainfall, but they can develop even in areas not currently experiencing precipitation. The waters can rise with surprising speed, leaving little time to prepare.

For instance, in North Alabama, flash flood warnings have been triggered by sudden heavy thunderstorms, causing flooding along roads, streams, and low-lying areas.

Immediate Actions to Take During a Flash Flood Warning

When a flash flood warning is issued, your priority should be safety. Here are the most important actions you can take:

• Seek higher ground immediately if you are in a low-lying or flood-prone area. Do not wait for official evacuation orders if you notice water rising quickly.
• Never drive through flooded roadways. Just 12 inches of moving water can sweep away a car. The phrase "Turn around, don't drown" saves lives for a reason. In some flash flood events, most fatalities have occurred in vehicles.
• Avoid walking through floodwaters. As little as six inches of swift-moving water can knock you off your feet. Floodwaters also conceal hazards, such as debris or open manholes.
• Monitor local alerts. Stay tuned to local news, NOAA Weather Radio, or trusted online sources. Timely alerts and situational updates can help you assess risk and act quickly.

Safety Tips During and After a Flash Flood

Your safety does not end when the rain stops. Keep these tips in mind:

• Don’t re-enter flooded buildings or basements until authorities say it’s safe. The risk of electrical hazards, contaminated water, and structural damage remains high.
• Avoid downed power lines and report them immediately. Do not go near any electrical equipment if it is wet or in standing water.
• Follow evacuation orders from local officials without delay. Secure your home and belongings if you have time, but never stay behind if told to leave.
• Disconnect utilities and major appliances to reduce risks of electrical shock and gas leaks when possible.
• If you become trapped by moving water, move to the highest accessible point and call 911 for help.

Combine these strategies with seasonal preparedness. For more guidance, refer to detailed weather safety resources specific to your region.

How to Prepare for Future Warnings

Advance preparation can give you peace of mind. Here’s how to get ready:

• Know your region’s flood risks. Low-lying and urban areas are often more susceptible to flash flooding.
• Create an emergency kit with essentials, such as food, water, flashlights, batteries, and first-aid supplies.
• Sign up for weather alerts from trusted sources like the National Weather Service. Many local apps also offer push notifications for severe weather.
• Plan evacuation routes in advance. Make sure everyone in your household knows where to go and how to get there safely.
• Review local resources and updates. Communities often provide additional guidance tailored to specific hazards and response plans.

Road and Vehicle Safety During Flash Floods

Traveling during a flash flood warning is dangerous. Here are quick tips to stay safe on wet roads:

• Allow greater distance between vehicles and avoid sudden braking.
• Stick to the middle lanes and reduce speed to prevent hydroplaning.
• If your visibility drops, pull over to a safe area away from traffic. Keep your hazard lights on while you wait for conditions to improve.
• Avoid parking near creeks, culverts, or drainage ditches.
