(Redirected from Flash Flood Warning) A flash flood warning (SAME code: FFW) is issued when a flash flood is imminent or occurring in the warned area. A flash flood is a sudden, violent flood after a heavy rain, or occasionally after a dam break. Rainfall intensity and duration, topography, soil conditions, and ground cover contribute to flash flooding.
Flash floods are a risk at all times of the year. While in the area, listen to local radio stations for the latest weather. In general, the National Park Service will close the river to non-motorized vessels when the river level reaches two feet above normal. Those flood levels are indicated at the right.
