Los Angeles County Coastal Areas, Including Marina del Rey, Under Tsunami Advisory Following Undersea Disturbance

In the early hours of Wednesday, the Los Angeles County coastline, including the area of Marina del Rey, braced themselves for tsunami waves prompted by a distant undersea disturbance. An advisory was issued by the U.S. Tsunami Warning Center cautioning of potential waves measuring 1 foot or less, as detailed in an announcement from the L.A. County Department of Beaches and Harbors (DBH). As the waves were anticipated to pummel the coast beginning around 1 a.m., several reactive measures were put forth.

DBH officials have to actively coordinate with local agencies to ensure the safety of Marina residents and the broader community. Measures they took included the closure of beaches, restrooms, accessways, and parking lots, as well as the repositioning of heavy equipment and boats to higher ground. Events under the department's sponsorship for Wednesday morning were summarily canceled. The L.A. County Department of Beaches and Harbors advised "People should stay away from beaches, harbors, marinas and waterways due to strong waves and currents." Guests at Dockweiler RV Park were not left in lurch; arrangements for alternate parking were being set in place.

Concurrently, an extended advisory was cast on other coastal regions. The NWS Los Angeles, in a notice shared on their official webpage, highlighted that, "Rising Water levels and strong currents may affect all beach areas, especially harbors and marinas." The advisory also underscored that the forthcoming tsunami waves, distinctively more robust north of Point Conception, would spell trouble for ports and harbors within L.A., Ventura, Santa Barbara, and San Luis Obispo Counties. According to the NWS Los Angeles post, "Widespread Inundation is NOT expected, but damage within harbors is possible - ESPECIALLY FOR AREAS NORTH OF POINT CONCEPTION, INCLUDING PORT SAN LUIS AND MORRO HARBOR."

Maintaining a stance of vigilance, authorities also emphasized the multiphasic nature of tsunamis. "Tsunamis typically arrive as a series of waves, which can to be dangerous for MANY hours after the first wave," was a warning issued on behalf of the National Weather Service. Given these threats, the NWS Los Angeles suggested two courses of action: "Go away from the coast, or if in a boat, go out to deep water!" Both residents and marine operators have thus been urged to measure their proximity to danger carefully, and to heed the guidance provided by county officials.

Residents in affected areas are urged to sign up for real-time alerts at Alert.LACounty.gov and to keep abreast of updates through local news and official County channels. The middle-tier advisory presently in place serves as a potent reminder of the volatile surge one confluence of earth and water can produce, and how crucial it is to heed the clarion call of preparation and precaution.
