...High surf advisory remains in effect until 6 PM PDT Friday...
* surf and timing...high surf will continue through Friday. The peak of the surf will occur today...with maximum sets of 10 to 15 feet likely on south and southeast facing beaches of Los Angeles and Ventura counties.
* Coastal flooding...minor coastal flooding will be possible across low lying areas near south and southeast facing beaches through Friday...especially near times of high tide.
* Tides...the next high tide will be near 5 feet around 11 am PDT today.
* Locations...in Los Angeles County...the highest surf will impact beaches from Long Beach through the Palos Verdes Peninsula...including Cabrillo Beach and Point Fermin...as well as Malibu and Zuma beaches. In Ventura County...beaches at or near Port Hueneme...Point Mugu...County line...and Oxnard Shores will be most impacted by the high surf.
* Impacts...this powerful surf event has the potential to produce structural damage to piers and beach side property as well as significant beach erosion. The powerful surf with very strong rip currents and long shore currents will create extremely dangerous swimming and surfing conditions... potentially life threatening. Sneaker waves can bring unexpectedly large waves across rocks and jetties near the Waters Edge...and suddenly inundate beaches.
Emergency and marine interests should begin to take necessary precautions to prepare for the possibility of a damaging surf event for south and southeast facing beaches. The Palos Verdes Peninsula...including Long Beach...Cabrillo Beach...and Point Fermin will be especially vulnerable in the early stages of the event due to the southeast direction of the initial swell energy this afternoon through tonight.
If you do not have to be in the water...stay on the shore. Stay off rocks and jetties and away from the Waters Edge to avoid being swept away by sneaker waves. Never turn your back to the ocean.
Remember...if caught in a rip current...swim parallel to shore until you are free of the powerful current.
