Flood Safety Tips:

Monitor local media, sign 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, 1 foot can sweep away a small car,
  • and 2 feet of water can carry away most vehicles.
  • 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.

Don’t touch or go near fallen or dangling power lines. Call 911.

  • Always assume that a fallen power line is live, and follow these guidelines:
  • Avoid touching the downed line — with your hand or an object, such as a stick, or broom.
  • Avoid touching anything in contact with a fallen power line, such as a car, object or equipment, or person.
  • Avoid driving over a fallen power line.
  • Call 911 immediately to report a fallen power line.
  • If a power line touches your car, stay inside your car. Call 911 and wait for emergency help.
