LOS ANGELES — High winds again will buffet parts of the Southland this morning.
A wind advisory reflecting a forecast of winds or gusts of at least 35 miles per hour will be in effect until noon in Los Angeles County in the San Gabriel and Santa Monica Mountains and the San Fernando and Santa Clarita valleys.
Winds of between 20 and 30 miles per hour are expected in the mountains while in the valleys the wind is forecast to blow at between 15 and 30 mph. Gusts of 45 mph are expected in both the mountains and valleys, according to the NWS.
“Winds this strong may down trees and power lines,” warned an NWS statement focussing on conditions in mountain areas. “The combination of the winds and the recent rain could lead to downed trees.”
In the valleys, “the strongest winds will occur in the northwestern San Fernando Valley” and coastal valleys in Ventura County, it said.
In both the mountains and valleys, “gusty winds will make driving difficult, especially for drivers of high-profile vehicles,” the NWS cautioned. “When driving, use extra caution. Be prepared for sudden gusty crosswinds.”
The NWS reported that it has recorded strong wind gusts since Sunday. The strongest have included 74 mph on Santa Catalina Island, 64 mph in the Malibu Hills, 59 mph in the San Gabriel Mountains, 57 mph in Malibu, 53 mph in the Santa Clarita Valley, 49 mph in the San Fernando Valley, and 44 mph in the Antelope Valley.
Temperatures will be a few degrees higher today than Monday, ranging from the low to mid-70s under sunny skies in L.A and Orange counties, and climb a few degrees Wednesday, again under sunny skies. Showers are expected in L.A. County on Christmas Eve. Christmas Day is forecast to be partly cloudy, with highs in the low 60s.
The Los Angeles County Department of Public Health, meanwhile, issued a cold weather alert for much of the county through today and in the Antelope Valley through Friday.
“Children, the elderly and people with disabilities or special medical needs are especially vulnerable during such cold snaps,” said Dr. Jeffrey Gunzenhauser, the county’s interim health officer. “Extra precaution should be taken to ensure they don’t get too cold when they are outside.”
The cold weather alert in effect through today applies to Los Angeles County mountains, Pomona and the San Gabriel and Santa Clarita valleys. The alert will be in effect through Thursday in the San Fernando Valley and through Friday in the Antelope Valley.
County officials warned residents not to use stoves, barbecues or ovens to heat their homes, noting that such appliances can produce deadly carbon monoxide.
Temperatures will be a few degrees higher today than Monday. The NWS forecast sunny skies today and 59 degrees Fahrenheit in Palmdale and Lancaster; 67 on Mount Wilson; 68 in Saugus; 72 in Avalon; 74 in Burbank; 75 in downtown L.A., Woodland Hills and San Gabriel; 76 in Pasadena and at LAX; and 77 in Long Beach.
Sunny skies were also forecast in Orange County, along with highs of 68 in Laguna Beach; 69 in Newport Beach and San Clemente; 74 in Mission Viejo; 75 in Yorba Linda; 76 in Irvine; and 77 in Anaheim and Fullerton.
Temperatures will climb marginally in L.A. County under partly cloudy skies Wednesday, while in Orange County they will climb slightly, stay the same or decline a few degrees, according to an NWS forecast. Rain is forecast on Chrstmas Eve amid low temperatures -- the high 50s and low 60s -- with more low temperatures expected on Christmas Day, along with partly cloudy skies.
