* WHAT...Minor to moderate coastal flooding expected, with isolated significant flooding possible especially on Sunday. Elevated surf and dangerous rip currents expected.

* WHERE...Catalina and Santa Barbara Islands, Ventura County Beaches, Malibu Coast and Los Angeles County Beaches.

* WHEN...Until 2 PM PDT Tuesday.

* IMPACTS...Moderate flooding of sea water is likely over some vulnerable low-lying coastal areas, 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 possible in most vulnerable areas, such as the Alamitos Peninsula in Long Beach. 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...The greatest risk for coastal flooding is on Sunday, when extreme tides, large waves, and strong winds could all peak together. A targeted Coastal Flood Warning may be considered if future guidance increases the chance of an extreme scenario. High tides of 7.0 to 7.6 feet will be common each morning, with large secondary high tides in the evening hours.

* WHAT...Southwest winds 20 to 35 mph with gusts up to 50 mph expected. Local gusts to 60 mph are possible over mountains and foothills.

* WHERE...Antelope Valley, Eastern Antelope Valley Foothills, Eastern San Gabriel Mountains, Interstate 5 Corridor, Western Antelope Valley Foothills, and Western San Gabriel Mountains and Highway 14 Corridor.

* WHEN...From 5 AM Sunday to 5 AM PDT Monday, with strongest winds expected in the late morning through late evening hours.

* IMPACTS...Tree limbs could be blown down and a few power outages may result. Higher chances of downed trees in areas that receive moderate rainfall. Gusty winds will blow around unsecured objects.

* WHAT...For vulnerable south-facing beaches, especially Long Beach and Malibu, damaging sea-water flooding is likely. For all other beaches and harbors, minor coastal flooding is expected. High surf of 5 to 8 feet is also expected with strong rip currents.

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

* WHEN...For the Coastal Flood Warning, until 3 PM PDT Sunday. For the High Surf Advisory, from 6 AM to 10 PM PDT Sunday.

* IMPACTS...For vulnerable south-facing beaches, sea-water flooding can damage beach roads and structures, especially around the time of high tide. For all other beaches and harbors, shallow and minor sea-water flooding can impact beaches and walkways. For all beach areas, significant 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...Sunday carries the widest range of coastal flooding outcomes due to chances of rain, wind, low pressure tidal enhancements, and swells from multiple directions. Coastal flooding impacts on Sunday could be similar to other days, or greatly enhanced. High tides of 7.3 to 7.6 feet will be common each morning. This warning may be extended past Sunday, or converted to a Coastal Flood Advisory through Tuesday.
