Oceanside CA- The National Weather Service in San Diego has issued a Coastal Flood warning effective 6:00 a.m. today, February 28 through March 2, 1:00 a.m. and a High Surf Advisory in effect from March 1, 4:00 a.m.- March 3, 4:00 a.m.. A coastal flood warning means that flooding is occurring or imminent. Coastal residents in the warned area should be alert for rising water and take appropriate action to protect life and property. A High Surf Advisory means that high surf will affect beaches in the advisory area producing rip currents and localized beach erosion.
A powerful pacific storm will generate large, rough surf and strong rip currents Friday morning through early Monday morning. Surf will begin to increase Friday and peak Saturday. The combination of high surf, high tides above 6.5 feet, strong onshore winds and rainfall runoff will likely result in widespread minor coastal flooding. More vulnerable areas may experience more significant coastal flooding which could result in property and structural damage on Friday.
A large west-southwest swell arriving Saturday morning will likely generate surf up to 15 feet along the beaches of Orange and San Diego counties. This will continue the threat of minor to possibly major coastal flooding during times of high tide for Saturday. Swell and surf will rapidly subside Sunday afternoon, ending the coastal flooding threat. Surf is forecast to fall below 7 feet on Monday.
