The cold front, which swept down from the north but brought little moisture, helped push some of those high winds down toward the surface, Kittell added. In Los Angeles, the number of Department of Water and Power customers without power jumped to nearly 100,000 customers, at one point increasing by 40,000 in less than two hours, said the utility’s Gale Harris. Hardest hit were Woodland Hills, Van Nuys, Winnetka, North Hollywood, Eagle Rock, Highland Park, Sylmar, Toluca Lake, Silver Lake, Atwater and the Los Feliz areas of Los Angeles, Harris said. Gusting winds were howling across many parts of the Southland, uprooting large trees in Toluca Lake and Sherman Oaks. The National Weather Service issued wind advisories in the San Fernando, San Gabriel and Santa Clarita valleys, and issued high wind warnings in the Antelope Valley and Los Angeles County mountains. The Weather Service reported peak winds Thursday of 45 mph in Van Nuys, 48 mph in Burbank, 35 mph in downtown Los Angeles and 54 mph in Lancaster.

You’re all set! In La Mirada, a tree was blown over into the street on Weeks Drive at La Mirada Boulevard, which caused no damage or injuries, and was quickly cleaned up, said Norwalk sheriff’s Lt. Myron Johnson. In La Puente, the winds knocked a basketball hoop onto a 52-year-old woman about 1 p.m., said Lt. Jaime Baltazar of the sheriff’s Industry station. There was no report on her condition. Baltazar also said a fallen electrical wire started a small backyard grass fire on Eseverri Lane in La Habra Heights. The passing of a cold front overnight Wednesday combined with a southern shift of the jet stream to cause the high winds, said metereologist Ryan Kittell of the National Weather Service. “One of the main reasons was the jet stream right over us, which only happens a few times a year,” said Kittell of the high-altitude winds, which typically travel at speeds upwards of 130 mph at 30,000 feet. WHITTIER – High winds knocked out electricity Thursday to more than 110,000 Los Angeles Department of Water and Power and Southern California Edison customers, authorities said. As of 7 p.m., about 2,200 Edison customers in the San Gabriel Valley remained without power, said Edison spokesman Steven Conroy. Montebello customers had the longest waits to get their power back on, said Conroy, though Sierra Madre, San Gabriel, Arcadia, Alhambra, and Monrovia also had power outages lingering into the night. A tree in a residential neighborhood was blown over and fell onto a car about 3 p.m. on El Braso Drive near Messina Drive in Whittier, said Whittier police Sgt. Carlos Solorza, but no other damage or wind related problems were reported.
