San Diego County hurricane guide¶

The County of San Diego Office of Emergency Services (OES) coordinates the overall county response to disasters and runs AlertSanDiego. The county lists flooding among the disasters San Diego is most at risk for, and its flood guidance says never to walk, swim, or drive through flood waters. Eastern Pacific tropical storms and their remains can bring heavy rain and flash flooding to this county.
