California, Oregon, and Washington under tsunami advisory: When will the tsunamis arrive?
The entire U.S. West Coast is under a NWS tsunami advisory. Here’s the latest on when the dangerous waves could arrive.
Russia’s Kamchatka peninsula was hit by an 8.8 earthquake on July 29—the largest earthquake on record in over a decade.
The National Weather Service (NWS) has issued a Tsunami Advisory for the coastal areas of California, Oregon, and Washington. These advisories are in addition to those already in place for American Samoa and Guam, as well as the more severe tsunami warnings issued for Hawaii and parts of Alaska.
In California’s largest coastal cities—San Francisco and Los Angeles—residents are being urged to stay away from beaches and waterways until authorities declare them safe. This guidance applies broadly to all coastal areas, as conditions can deteriorate rapidly and may not allow enough time to reach higher ground.

When will the tsunami conditions arrive along the West Coast?
Here’s a look at the expected arrival times from the NWS as of 7:25 pm PT.
In parts of California, the National Weather Service has upgraded its alert from a tsunami advisory to a tsunami warning, urging residents from Cape Mendocino to the Oregon border to evacuate and seek higher ground. Dave Snider, the Tsunami Warning Coordinator for the National Tsunami Warning Center, advises that those under a warning should move at least one mile inland or to an elevation of 100 feet above sea level. However, he emphasized that people in the affected areas should follow the instructions of local authorities. The most up-to-date information on tsunami warnings can be found on the NWS’ website.

The Los Angeles NWS expects to see larger tsunami waves in the Point Conception area. "Go away from the coast, or if in a boat, go out to deep water," advises the NWS office.
At this point, widespread flooding is not expected in the area. The waves could last for hours, and the first to arrive are not likely to be the largest in the series that will hit the coastal areas.
Seattle’s NWS office has issued similar warnings. Flooding could take place near beaches, harbors, and marinas, and residents are advised to move away from the shore until told it is safe to return. “DO NOT attempt to go to the shore to observe the tsunami,” urged the weather office.
