* WHAT...For the High Surf Advisory, large breaking waves of 5 to 8 feet today, increasing to 8 to 12 feet Saturday. Surf heights are expected to decrease to 5 to 9 feet Sunday through Tuesday. Dangerous rip currents expected. For the Coastal Flood Advisory, minor to moderate coastal flooding expected.

* WHERE...Malibu Coast and Los Angeles County Beaches. Surf will we highest for west-northwest facing beaches.

* WHEN...For the High Surf Advisory, until 3 PM PST Tuesday. For the Coastal Flood Advisory, from 4 AM to 4 PM PST Saturday.

* IMPACTS...Moderate flooding of sea water is likely over some vulnerable low-lying coastal areas that are normally dry, especially around the time of high tide, including over beach parking lots, bike paths, and harbor walkways. Moderate to significant beach erosion is likely. Isolated damage is unlikely but possible. 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...A series of significant west- northwesterly swells are expected to produce large surf into next week with highest surf and greatest impacts likely peaking Saturday and potentially again Monday. Minor to moderate coastal flooding impacts are possible, especially when largest surf overlaps with peak high tides. Some of these impacts may be moderate to significant beach erosion and shallow flooding of normally dry beaches and walkways.

* WHAT...For the Beach Hazards Statement, dangerous rip currents and breaking waves due to elevated surf. For the High Surf Advisory, large breaking waves of 4 to 7 feet Friday, increasing to 7 to 12 feet Saturday. Surf heights are expected to decrease to 6 to 9 feet Sunday through Tuesday.

* WHERE...Malibu Coast and Los Angeles County Beaches.

* WHEN...For the Beach Hazards Statement, until 2 PM PST this afternoon. For the High Surf Advisory, from 2 PM this afternoon to 3 PM PST Tuesday.

* 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.

* ADDITIONAL DETAILS...A series of significant west- northwesterly swells are expected to produce large surf into next week with highest surf and greatest impacts likely peaking Saturday and potentially again Monday. There is potential for moderate coastal flooding impacts at times, especially Saturday. Some of these impacts may be moderate to significant beach erosion and shallow flooding of normal dry beaches and walkways.
