Torrential downpours were inundating Southern California on Friday, flooding streets and prompting water rescues. Officials said at least two people had died in the storm. One was found in a vehicle that was under water. Here are the latest developments from one of the worst storms in the area in recent memory: A motorist in Victorville was found dead when San Bernardino County firefighters searched a submerged car. The department didn't give any details about the victim. • Eight people were rescued when 10 vehicles got stuck on a road in Sun Valley. No one was injured, the Los Angeles Fire Department said. • In just four hours, beginning at noon, the fire department responded to 150 calls of downed power lines. • It was snowing heavily at higher elevations. "Chains required in all mountain areas. Unknown duration," tweeted the California Department of Transportation office for Riverside and San Bernardino counties.
