Tips to Stay Safe

A Flood Watch means the area may experience a dangerous flooding event, and being prepared may save lives and property. 

  • Be aware of low-lying areas along your travel routes that are most likely to flood. 
  • Check your home’s emergency supplies, and make sure all members of the household know your emergency plan
  • Stay tuned for local weather updates on the situation as it develops.

If a Flood Warning is issued, it means that dangerous flooding is expected or already happening. 

  • 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 your home is likely to flood, or if authorities tell you to evacuate, do so immediately and move to higher ground.
