Flash floods occur within few minutes or hours of excessive rainfall. This may be caused by a blocked stormwater drain or a dam failure or a severe and heavy rainstorm. Nearly half of all flash flood deaths are auto related, so never drive or let anyone drive through flood waters! Roads could be washed out under the running water. And if your car stalls in just two feet of moving water, the water will have enough force to lift up your car and carry it away!

If a flash flood warning has been issued for your area, act immediately! You may only have seconds before flood water appear.


  • If you are outdoors and flash flood is likely, get to higher ground immediately! You cannot outrun a flash flood.
  • Keep out of places that are likely to flood such as ditches or dry stream beds.
  • Avoid already flooded areas and high velocity flow areas.
  • Never attempt to run across flooding water when the water is above your ankles.
  • If you are in a car during a flood, never drive through flooded roadways! Turn away around and go the other director.
  • Drive with caution when it is raining
  • Do not walk into or near high water.
  • Keep children from drainage ditches and stormwater drains.


  • NEVER drive into water covering the road. You do not know how deep it is or if the road is washed away.
  • Turn around and go the other way!
  • Look out for flooding at highway dips, bridges and low areas.
  • If the vehicle stalls, leave it immediately and seek higher ground.
  • Be cautious, especially at night when its visibility is impaired.
  • Do not park your vehicle along streams and washes, particularly during threatening conditions.
