  • Stay away from streams, drainage ditches and low lying areas prone to flooding.
  • Rainfall and runoff will also cause hazardous driving conditions due to ponding, reduced visibility and poor braking action.
  • Do not cross fast flowing or rising water in your vehicle, or on foot. Turn around, don’t drown.

This advisory may need to be extended beyond 9:45 p.m. if heavy rain persists.
