* WHAT...Large breaking waves of 10 to 15 feet on Saturday, 15 to 20 feet on Sunday, 18 to 25 feet Monday afternoon through Tuesday. Very dangerous rip currents. For the Coastal Flood Advisory, coastal flooding expected. * WHERE...San Luis Obispo County Beaches and Santa Barbara County Central Coast Beaches, largest on west to northwest facing shores. * WHEN...For the High Surf Advisory, until 1 AM PST Sunday. For the High Surf Warning, from 1 AM Sunday to noon PST Tuesday. For the Coastal Flood Advisory, from 2 AM Sunday to 9 AM PST Tuesday. * IMPACTS...Flooding of sea water is likely, around the time of high tide, over vulnerable low-lying coastal areas such as parking lots, beaches, and walkways. Significant damage to roads or structures is NOT expected. Powerful waves and strong rip currents will pose an exceptional risk of ocean drowning and damage to coastal structures like piers and jetties. Large breaking waves can cause injury, wash people off beaches and rocks, and capsize small boats near shore. * ADDITIONAL DETAILS...High tides between 4.0 and 5.0 feet MLLW are expected each morning between 3 and 6am. The risk for shallow but impactful coastal flooding is highest during these times, with flooded beach roads and parking lots possible, especially for the Oceano Dunes area. Monday night through Tuesday morning pose the greatest risk for coastal flooding and high surf.
