LOS ANELES, Oct. 13 (Xinhua) -- Thousands of residents living in Los Angeles and nearby Orange county suffered power outage Saturday morning after a thunderstorm passed through Southern California area Friday night.

"There are approximately 10,000 customers without power. We apologize for the trouble. Our field crews are working hard to restore power as quickly and safely as possible," Los Angeles Department of Water & Power (LADWP) tweeted at 9:49 p.m. Friday, two hours after lightning could be seen and thunder heard across a wide swath of the region.

The latest report from the LADWP issued Saturday morning showed that there were 2,800 customers across Los Angeles still without power, many along the foothills of the San Gabriel Mountains.

Friday's thunderstorm brought a shower to the region, the National Weather Service said. By about 8 p.m., 0.33 inches (0.84 cm) of rain had fallen in 15 minutes at Cheviot Hills observation point, 17 kilometers west of Los Angeles downtown.

There was no report of casualty in the thunderstorm but many local residents were scared by the lightning, which forced officials to warn local residents to stay indoors.

Douglas Erber, who grew up in Huntington Beach of Los Angeles, told local CBS news channel that he had "never seen anything like this."

"This is something you see in Indonesia or Mexico City, so it was pretty exciting and I was glad our kids weren't too worried about it," he said.
