What to Do Before Flooding Occurs

  • If it has been raining hard for several hours, or steadily raining for several days, be alert to the possibility of a flood. Floods happen as the ground becomes saturated.
  • Use a NOAA Weather Radio or a portable, battery-powered radio (or television) for updated emergency information. Local stations provide the best advice for your particular situation.
  • Listen for distant thunder. In some types of terrain, runoff from a faraway thunderstorm could be headed your way.
  • If you are stopping your vehicle, camp or park away from streams and washes, particularly during threatening conditions. Flood waters can rise quickly and carry you or your belongings away.
  • When in or along stream channels, be aware of distant events, such as dam breaks or thunderstorms that may cause flash floods in the area.
