WEATHER ALERT: Tsunami advisory in effect for state of California

U.S. Coast Guard Pacific Southwest Public Affairs: (206) 815-6689

ALAMEDA, Calif. -- As of 9:26 PDT, the National Weather Service has initiated a Tsunami Warning from Cape Mendocino to north of the California/Oregon border. An Advisory is in effect from Cape Mendocino to the California/Mexico border.

According to the National Weather Service, a tsunami is expected that could create strong currents posing risks to swimmers, boats, and coastal infrastructure. While widespread flooding is not anticipated, damage within harbors is possible. Water surges in and out of harbors may cause boats and docks to break free from their moorings. 
 

***RECOMMENDED ACTIONS***



If you are within a tsunami warning area, evacuate inland or to higher ground above and beyond designated tsunami hazard zones or move to an upper floor of a multi-story building depending on your situation. 

If you are within a tsunami advisory area, move off the beach and out of harbors and marinas. 

DO NOT go to the coast to watch the tsunami. 

The Coast Guard urges those within areas at risk for impact to monitor local weather advisories for warning level updates and evacuation orders.
