High surf will batter the Southland coast Thursday as a storm takes aim at the region, poised to strike as early as Friday night to usher in at least five days of rainy weather, forecasters said.
A high surf advisory will be in force in L.A. County until 9 this evening and in Orange County for an hour more.
Surf of between 7 and 10 feet with maximum sets of 12 feet is possible at west-facing beaches in Los Angeles County through Thursday morning, the National Weather Service said in a statement. Surf will likely subside to 6 to 9 feet through this evening, the weather service said, adding that high surf is also possible again over the weekend.
In Orange County, surf of 6-12 feet is forecast Thursday morning before gradually susiding, according to the NWS.
NWS forecasters said the surf could cause minor coastal erosion and dangerous conditions for swimmers and surfers.
“Swim near a lifeguard,” advised the NWS statement. “If caught in a rip current, relax and float. Don’t swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.”
Forecasters say the high surf is the result of a big swell created by winds generated by storms lined up in the northeastern Pacific. One of those storms is expected in California Friday, with rainfall expected in the Southland late in the evening and on Saturday.
The event should produce between a half-inch and an inch of rain in L.A County, along with slick roads, traffic delays, minor rockslides and debris flow, forecasters warned. In the San Gabriel Mountains, the snow level will be at 6,000 feet or above, NWS forecasters said.
But that will not be the end of it. An extended NWS forecast shows mostly cloudy skies in L.A. County Friday, showers on Saturday, followed by rain every day through Wednesday.
Some precipitation is also in Orange County’s future, with the extended forecast showing showers in Orange County on Monday, Tuesday and Wednesday.
The NWS forecast partly cloudy skies in L.A. County Thursday and highs of 57 degrees on Mount Wilson; 60 in Palmdale; 61 in Lancaster; 62 in Avalon and at LAX; 64 in Long Beach; 65 in San Gabriel and Burbank; 66 in Downtown L.A., Pasadena and Saugus; and 67 in Woodland Hills.
A combination of sunny and partly cloudy skies is expected in Orange County Thursday, along with highs of 52 on Santiago Peak; 59 on Ortega Highway at 2,600 feet; 61 in San Clemente; 62 in Fremont Canyon and Laguna Beach; 63 in Newport Beach and Yorba Linda; 65 in Trabuco Canyon and Mission Viejo; and 66 in Fullerton, Anaheim and Irvine.
