  • Most flash flood fatalities occur at night and most victims are people who become trapped in automobiles.
  • Six inches of fast-moving water can knock you off your feet; a depth of two feet will cause most vehicles to float.


  • Avoid walking, swimming, or driving in flood waters.
  • Stay away from high water, storm drains, ditches, ravines, or culverts. If water is moving swiftly, even a six inch depth can knock you off your feet.
  • If you come upon flood waters, stop, turn around, and go another way. Climb to higher ground.
  • Do not let children play near storm drains.
  • Check the weather forecast before leaving for extended outdoor trips. Watch for signs of approaching storms.
  • If a campground’s alarm system relies on electricity, have an alternate method to notify campers in case of power failure.
  • NOAA Weather Radio is the best means to receive warnings from the National Weather Service.


  • Flash Flood Watch: Flash flooding is possible in your area. Remain alert for quickly rising water. Know what counties or parishes are in the watch area by listening to NOAA Weather Radio or your local radio/television outlets.
  • Flash Flood Warning: Flash flooding is imminent or has already been reported.
