Caught in a Flash Flood? Here’s How to Stay Safe
When it comes to natural disasters, flash floods are some of the most dangerous — and the most sudden. Caused by heavy rainfall, overflowing rivers, or sudden dam breaks, a flash flood can develop within minutes, turning streets into rivers and bringing water into the home.
What is a Flash Flood?
Flash floods are rapid-onset floods that typically occur within six hours of heavy rain. Unlike slow-rising river floods, flash floods offer little to no warning, making them especially dangerous in urban areas where concrete limits natural drainage.
They can wash out roads, trap vehicles, damage homes, and put lives at risk — which is why awareness and preparation are key.

Before the Flood: Know the Risks
- Understand your area’s flood potential.
Are you in a low-lying zone or near a creek or drainage ditch? Use FEMA’s flood maps or contact local emergency services to learn your risk level. - Sign up for alerts.
Enable Wireless Emergency Alerts (WEAs) on your phone, or download apps like FEMA or the Red Cross Emergency app to receive real-time notifications. - Prepare an emergency kit.
Pack essentials: bottled water, non-perishable food, flashlights, batteries, first-aid supplies, medications, a power bank, and copies of important documents. - Make a family plan.
Know where you’ll meet if separated and how you’ll communicate. Practice your evacuation plan regularly.
During the Flood: Act Quickly and Safely
- Move to higher ground.
If flooding is likely or already occurring, leave immediately. Do not wait for instructions if you’re in a known flood zone. - Never walk or drive through floodwaters.
Six inches of fast-moving water can knock a person off their feet. A foot of water can carry away most vehicles. Turn around — don’t drown. - Leave stalled vehicles.
If your car is trapped in water, abandon it and seek higher ground, as long as it’s safe to do so. - Stay tuned.
Keep a battery-powered radio or phone handy for weather updates and evacuation instructions. Cell towers may be impacted during severe weather.
If You’re Inside:
- Avoid basements or lower levels. These flood first and fast.
- Disconnect electrical appliances (if safe to do so) to prevent shock or fire hazards.
- Grab your emergency kit and move to an upper floor if evacuation isn’t possible.
After the Flood: Stay Cautious
Even after the rain stops, hazards remain.
- Don’t return home until officials say it’s safe.
Floodwaters can damage roads, weaken foundations, and contaminate water supplies. - Avoid contact with floodwater.
It can contain sewage, chemicals, and debris. Wear protective gear if you must clean up. - Document any damage.
Take photos before starting any repairs. Notify your insurance company right away.
Flash Flood Safety Quick Tips:
- Turn around, don’t drown.
- Stay off bridges over fast-moving water.
- Don’t camp or park near creeks or washes during storms.
- Avoid using candles for light during power outages — opt for battery-powered lights instead.
- Keep emergency numbers easily accessible.
