Santa Ana winds gusted across parts of the Southland Thursday, driving up temperatures and creating hazardous driving conditions, but even more fierce winds are anticipated Friday into Saturday.
Wind advisories will be in place for the Los Angeles County Mountains, excluding the Santa Monica Range, as well as for the Santa Clarita and San Fernando valleys until 6 p.m. Thursday. Northeast winds of 20 to 30 mph, with gusts up to 50 mph, are expected.
Orange County inland areas will be under an advisory until 4 p.m. North winds from 15 to 30 mph are in the forecast, with gusts over 50 mph in mountain passes and canyons, and over 35 mph in the valleys. The strongest winds will be confined to areas near and below the major passes, and below wind-prone canyons along the coastal slopes and foothills.
High winds will also affect parts of Ventura and Riverside counties.
The advisories came with warnings that the high winds can blow around unsecured objects and make driving difficult, especially for high-profile vehicles. Areas noted by the weather service for caution include the Golden State (5) and Antelope Valley (14) freeways.
In addition, tree limbs could be blown down and a few power outages may result, the weather service said.
A more serious high wind warning will take effect at 3 p.m. Friday in the Santa Monica Mountains, the Santa Clarita and San Fernando valleys and the Los Angeles County Mountains. The warnings will remain in effect until 3 p.m. Saturday.
According to the NWS, the Los Angeles County Mountains could experience winds of 35 to 45 mph, with gusts of 70 mph, and isolated gusts potentially reaching 80 mph in the western portion of the San Gabriel Mountains. The other areas covered by the warning could see 25 to 35 mph winds, with gusts up to 65 mph — strongest in the Santa Monica Mountains and western and northern parts of the San Fernando Valley.
Wind advisories will be in effect from 3 p.m. Friday to 3 p.m. Saturday for the Los Angeles coastal region, including downtown, and the San Gabriel Valley. Forecasters anticipate winds of 20 to 30 mph, with gusts of 50 mph, in the coastal area, most notably near Malibu. The San Gabriel Valley could be hit with winds of 15 to 25 mph, and gusts up to 40 mph.
Forecasters said the winds could be “strong and potentially damaging.”
“Daytime temperatures will warm to above seasonal normals for this time of year as offshore flow will remain in place through the period, but in wind-sheltered areas and the interior valleys, overnight low temperatures could get quite cold,” according to the NWS.
