* WHAT...DAMAGING sea-water coastal flooding is likely through Sunday, especially near the Sunday morning high tide where anticipated tide levels are expected to be around 8 feet. The most likely areas for DAMAGING coastal flooding on Sunday morning will be vulnerable southeast facing beaches, such as Avalon and Pebbly Beach. For all other beaches and harbors, minor to moderate coastal flooding is expected. The most DAMAGING and WIDESPREAD coastal flooding risk along southeast beaches will likely be with the Sunday morning high tide due to the expected combination of very high level tide levels approaching 8 feet (including additive effect of low barometric pressure, high surf of 5 to 8 feet, and light to moderate rainfall. * WHERE...Catalina and Santa Barbara Islands. * WHEN...For the Coastal Flood Warning, until 3 PM PDT Sunday. For the Coastal Flood Advisory, from 3 PM Sunday to 2 PM PDT Tuesday. * IMPACTS...Sea-water flooding of beach and harbor roads, parking lots, and walkways is likely, especially around the time of high tide. Isolated damage is likely across southeast facing beaches near Sunday mornings high tide. Significant beach erosion is expected. There is an increased risk for ocean drowning. Rip currents can pull swimmers and surfers out to sea. Large breaking waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore. * ADDITIONAL DETAILS...High tides of around 8 feet are expected on Sunday morning, returning to around 7.5 feet for Monday and Tuesday mornings. Large secondary high tides are also expected each evening. Stay off of beaches and coastal walkways, roads, and structures. Do NOT drive around barricades or through water of unknown depth.
