During a Flash Flood

Residents should take the following action in the event of a flash flood:

  • Move to high ground immediately
  • Stay out of floodwaters. Swift-moving water and debris can be deadly
  • Stay away from power lines and electrical wires
  • Leaving the area can pose significant dangers, as road washouts and landslides can occur along escape routes. If you plan to try to leave the area, give yourself as much time as possible, and know that it still may not be enough time.

Vehicle Safety

  • Nearly half of all flash flood fatalities are vehicle-related. As little as 18 inches of water will float most automobiles.  
  • Never drive your vehicle through flood waters
  • While driving your vehicle, be aware of dips, culverts, bridges and low-lying areas 
  • If your vehicle stalls, leave it immediately and seek higher ground
