What is a flash flood warning?
A flash flood warning means water is rising fast, usually within six hours of heavy rain, a dam or levee failure, or an ice jam. Small streams, low-water crossings, urban underpasses and burn scars from wildfires are the most dangerous places. A "flash flood emergency" is the highest level and is used when severe threat to life and catastrophic damage are occurring.
Flooding kills more people in the United States in most years than tornadoes do, and about half of those deaths happen in vehicles. Moving water just six inches deep can knock an adult down, and about a foot of moving water can float many cars.
What to do
- Get to higher ground immediately if you are in a flood-prone area.
- Turn around, do not drown: never drive or walk into flood water.
- Stay away from creeks, drainage ditches and low-water crossings.
- At night, be extra careful; it is harder to see that a road is flooded.

Frequently asked questions
What is the difference between a flood warning and a flash flood warning?
A flash flood warning is for rapid, dangerous rises within hours. A flood warning usually covers slower, longer-lasting flooding such as rivers rising over days.
How much water can sweep a car away?
About 12 inches of moving water can float many cars, and two feet can carry away most vehicles, including SUVs and pickups.
