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.
