Driving in the rain during hail and lightning on the 710 Freeway Thursday afternoon, Dec. 15, 2011.
A thunderstorm moved through the Southland Thursday afternoon, leaving 13,838 Southern California Edison customers without power as of 6:30 p.m. with heavy rain, thunder and lightning in some areas, down from 20,000 earlier. The hardest hit areas are Arcadia, Long Beach, Covina, Rancho Cucamonga and Palm Springs, according to SoCal Edison.
The National Weather Service says thunder and lightning rolled through parts of Riverside and San Bernardino counties and northeastern areas of Los Angeles, including Pasadena and Burbank, late Thursday afternoon.
A high wind warning is in effect from 3 a.m. Friday to 3 p.m. Saturday. Stuart Seto of the National Weather Service said most valley areas could see 20- to 30-mile per hour winds, with gusts reaching 40 mph. Gusts may be up to 70 mph in the Los Angeles and Ventura County mountains.
The weather service says the most susceptible areas for the strong winds will be through and below northeast facing passes and canyons. Strong gusty winds also are expected across the valleys of Ventura County, the western San Fernando Valley, the Ventura County coast and Los Angeles County coastal sections below the Santa Monica range.
Seto said earlier Thursday afternoon that the storm was moving fast. "These first little band of showers should move through very quickly — about an hour to an hour and a half. But there’s some more showers behind it, so we do have showers in the forecast until midnight.”
