LOS ANGELES (CBSLA.com) — Strong winds swept through the San Fernando Valley Friday night and Saturday, reaching gusts of up to 60 mph, the National Weather Service reported.

It was enough to down trees, power lines and a large billboard when winds picked up around 2 a.m.

Crews restored power by 1 p.m. Saturday to 33,576 customers in the San Fernando Valley, which still left 20,572 others without electricity, according to the Department of Water and Power. By 6 p.m., 15,000 customers were still in the dark. They say crews will work until all power is reinstated.

Residents affected by the outage were located in the central portion of the Valley, south of Nordhoff Street and north of the 101 Freeway, stretching from Winnetka to the Burbank Airport.

A tree toppled onto a house in Van Nuys, the branches slicing through the roof and extending into the kitchen. No one was injured.
