Flood Safety Tips:

  • Stay informed by monitoring local media and signing up for alerts.
  • Turn Around, Don’t Drown!
  • Avoid walking or driving through flood waters.
  • Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your
  • vehicle away.
  • If there is a chance of flash flooding, move immediately to higher ground.
  • If floodwaters rise around your car but the water is not moving, abandon the car and
  • move to higher ground. Remain in the car if the water is moving.
  • Avoid camping or parking along streams, rivers, and creeks during heavy rainfall.

These areas can flood quickly and with little warning.
