Strong winds will buffet the Southland Thursday, but the showers that had been forecast in L.A. County will barely materialize, forecasters said.
The west-to-northwest winds will produce strong gusts in the wake of a weak front associated with a small storm out of Northern California, National Weather Service meteorologists said.
A wind advisory indicating an expectation of 35-mile-per-hour winds will go into effect at 7 Thursday morning in the Antelope Valley; at 1 Thursday afternoon on Santa Catalina Island and in the L.A coastal zone, which consists of L.A. County beach cities, metropolitan L.A., the downtown area, and the Hollywood Hills; and at 4 Thursday afternoon in the San Gabriel Mountains in Ventura and Los Angeles counties. In all three cases, the advisories are scheduled to expire at 3 a.m. Friday.
Expected on Santa Catalina and in Los Angeles are winds of between 15 and 25 miles per hour gusting to between 30 and 40 mph, according to the NWS. In the Antelope Valley and the San Gabriels, the wind is expected to blow at between 20 and 30 mph and produce gusts of between 40 and 55 mph, it said.
“Cross-winds can make driving difficult, especially for drivers of high-profile vehicles and vehicles towing trailers. Areas of blowing dust can suddenly and dangerously reduce visibilities to near zero,” warned an NWS statement. “When driving, use extra caution. Be prepared for sudden gusty cross-winds.”
But what until Wednesday morning had been a forecast of showers throughout L.A County has been withdrawn. NWS meteorologist Dave Bruno said showers are now expected only in southeastern L.A. County, and most L.A. County residents likely would be unaware of them.
The NWS forecast partly partly cloudy skies Thursday — except in San Gabriel and Mount Wilson — and highs of 53 degrees on Mount Wilson; 60 in Palmdale and Lancaster; 63 in Avalon; 64 at LAX; 66 in Saugus; 67 in Downtown L.A. and San Gabriel; 68 in Long Beach; and 69 in Pasadena, Burbank and Woodland Hills. Showers are forecast in San Gabriel, and snow showers on Mount Wilson at 5,713 feet.
Partly cloudy skies were forecast in Orange County, along with highs of 62 in San Clemente and Laguna Beach; 63 in Newport Beach and Mission Viejo; 66 in Irvine; 67 in Yorba Linda; 69 in Anaheim; and 70 in Fullerton.
Slightly higher temperatures are forecast over the next several amid a mix of sunny and partly cloudy skies.
