Floods kill more people in the United States than any other type of severe weather. Floods can roll boulders the size of cars, tear out trees, destroy buildings and bridges, and pose a significant threat to human life.
Flash Floods
A flash flood is a rapid rise of water along a stream or low-lying urban area. Flash flood damage and most fatalities tend to occur in areas immediately adjacent to streams or creeks, due to heavy rain. Flash floods can be produced when slow moving or multiple thunderstorms occur over the same area. Flash floods can take only a few minutes to a few hours to develop. Persons who live near streams or creeks prone to flooding should be alert during heavy thunderstorms to evacuate if necessary.
When a Flash Flood Watch is Issued
- Be alert to signs of flash flooding and be ready to evacuate in a moment's notice.
When a Flash Flood Warning is Issued
- Or if you think it has already started, evacuate immediately. You may have only seconds to escape. Act quickly!
- Move to higher ground away from rivers, streams, creeks, and storm drains. Do not drive around barricades... They are there for your safety.
- If your car stalls in rapidly rising waters, abandon it immediately and climb to higher ground.
