Coastal Flood Advisories and Record High Tides Affect California Coast

Exceptionally high tides have caused coastal flooding across California since October 26, leading to inundation of homes, businesses, and roads, and prompting a local emergency declaration in Huntington Beach. The National Weather Service has extended coastal flood advisories around San Francisco, San Pablo, and Monterey bays through November 1. Ocean levels along the entire California coast have reached record highs, with significant marine ecosystem disruptions reported. Southern California ocean water levels have reached their highest recorded levels in any month, and parts of northern California have exceeded October monthly records.
