NWS issues tsunami advisory for California coast
– The National Weather Service issued a tsunami advisory for the California coast on Tuesday evening following an 8.7 magnitude earthquake off the coast of Russia.
The advisory applies to all coastal areas of Los Angeles, Ventura, Santa Barbara and San Luis Obispo counties. Rising water levels and strong currents may affect all beach areas, especially harbors and marinas. NWS said in a post to X. “Go away from the coast, or if in a boat, go out to deep water!
Widespread inundation is not expected, but authorities warn that damage within harbors is possible, particularly for areas north of Point Conception. This includes Port San Luis and Morro Harbor. Officials said they are closely monitoring the situation in these Central Coast harbors.
Port San Luis is expected to feel the impacts at approximately 12:35 AM on July 30, reports say.
Tsunamis typically arrive as a series of waves, which can remain dangerous for many hours after the first wave. The first tsunami wave may not be the highest in the series.
Residents are encouraged to visit the county’s Tsunami Preparedness page for detailed information on tsunami watches, advisories and warnings.
