* WHAT...Large breaking waves of 5 to 7 feet with sets to 8 to 9 feet at northwest facing beaches. High rip current risk. * WHERE...San Diego County Coastal Areas and Orange County Coastal Areas. * WHEN...From 4 PM Friday to 10 AM PST Sunday. * IMPACTS...Dangerous swimming and surfing conditions and localized beach erosion. * ADDITIONAL DETAILS...Tides will be falling during this time, but adjusted high tides may still be near 7 feet which could combine with the high surf to result in localized beach erosion and overflow into parking lots and boardwalks. Surf begins to wane Sunday afternoon but may remain elevated for west-facing beaches into Monday morning.
