What Is a Flash Flood?

A flash flood is a rapid flood caused by heavy rainfall, typically within six hours. These floods can form quickly, even in places not directly receiving rain, and often turn into dangerous torrents.

Flash Flood Watch vs. Warning

Flash Flood Warning: Flooding is happening or imminent. Move to higher ground immediately.
Flash Flood Watch: Flooding is possible. Stay alert.

What to Do During a Flash Flood Warning

Evacuate if authorities tell you to.
Use a battery-powered radio for emergency updates.
Never walk through moving floodwaters — just 6 inches can knock you over.
Don’t drive into flooded roads — only 2 feet of water can carry away a vehicle.
Avoid electrical hazards and fire risks.
Keep kids away from flowing water — debris and currents can be deadly.
Turn on weather alerts and stay informed.

Remember: Turn around, don’t drown. Stay safe and avoid all flooded areas.
