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.
