* WHAT...Minor coastal flooding and dangerous rip currents expected due to the combination of high tides and elevated surf. * WHERE...San Diego and Orange County Coastal Areas. * WHEN...From Tuesday afternoon through Friday evening. * IMPACTS...There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea. Waves can wash people off beaches and rocks, and capsize small boats nearshore. Moderate flooding of sea water is possibly over some vulnerable low-lying coastal areas. Moderate beach erosion is possible to likely. * ADDITIONAL DETAILS...Elevated surf of 3-6 feet on south and southwest-beaches. High tides are expected to peak between 6.5 and 7.0 feet during the morning and evenings. There is a moderate chance that an upgrade to Coastal Flood Advisory and/or High Surf Advisory will be needed. These products will likely need to be extended into the weekend.
