What a flash flood warning means
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.

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.
