What is a flash flood?

A flash flood is a sudden, rapid flooding of low-lying areas, typically caused by heavy rainfall. Flash floods can occur within minutes or hours of heavy rain, and can be extremely dangerous.

If you are caught in a flash flood, the NWS recommends that you take the following steps:

• Move to higher ground immediately.
• Do not attempt to walk or drive through floodwaters.
• Stay away from bridges and culverts, as they can be washed out by floodwaters.
• If you are in a car, abandon it and move to higher ground.

There are several things you can do to prepare for a flash flood, including:

• Be aware of the flood risk in your area.
