* WHAT...For the Coastal Flood Advisory, moderate coastal flooding expected. For the High Surf Advisory, large breaking waves of 5 to 8 feet with local sets to 12 feet and dangerous and potentially life threatening rip currents, largest on south- facing shores. * WHERE...Catalina and Santa Barbara Islands, Ventura County Beaches, Malibu Coast and Los Angeles County Beaches. * WHEN...Until 11 PM PDT Tuesday. * IMPACTS...There is an increased risk for ocean drowning. Rip currents will be widespread and very strong, potentially pulling swimmers and surfers out to sea. Large breaking waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore. Significant beach erosion will occur. Flooding of sea water is likely, around the time of high tide, over vulnerable low-lying coastal areas such as parking lots, beaches, walkways, and low-lying roads. Of particular concern will be the Alamitos Peninsula area in Long Beach where coastal flooding will potentially cause local damage to structures near time of high tides, especially today. Other areas that will be susceptible to coastal flooding during the next couple of days include Catalina Island, and Oxnard to Malibu (including Point Mugu). * ADDITIONAL DETAILS...High tides will occur around 6.7 feet at 6pm on Sunday, 7 feet at 7pm on Monday, and 7.2 feet at 8pm on Tuesday. Remain out of the water due to dangerous surf conditions, or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions, stay off the rocks. Follow advice from local officials. Do NOT drive around barricades or through water of unknown depth.
