Heavy rain produces flooding on Sunset Boulevard in Fort Walton Beach, Fla., in early February 2016.

A Flash Flood Watch is issued when flash flooding conditions -- a rapid and extreme flow of high water into a normally dry area or a rapid water level rise in a body of water due to intense rainfall, dam failure or ice jam -- are favorable.

A Flash Flood Warning is issued when flash flooding is occurring or imminent.

Residents living in low-lying areas or near a body or water should listen to the local radio and TV stations for continuous updates.  If told to evacuate, do so as soon as possible.

Safety tips:

  • Avoid walking through floodwater - swiftly moving water 6 inches can sweep you off your feet.
  • Do not drive through flooded areas; it only takes 2 feet of water to carry away most automobiles.
  • If the car stalls while in the water abandon the car and find higher ground. "Turn Around, Don`t Drown."\
