A Flood Warning means that dangerous flooding is expected or already happening. Take immediate action to protect yourself and your home. 

  • If your home is likely to flood, or if authorities tell you to evacuate, do so immediately and move to higher ground. 
  • Never walk, swim, or drive through flood waters or flooded roads. 
  • Stay away from areas where water levels can rise rapidly, like storm drains, culverts, creeks and streams. 
  • If you are trapped in a building, move to the highest floor and call 911. Go to the roof only if necessary.
