Thunderstorms that swept across Southern California on Sunday led to the death of one person and caused mountain mudslides that stranded more than 2,000 others, authorities said. A body was found in a car that was swept into a rain-swollen creek in Mount Baldy and overturned, San Bernardino County Fire spokesman Chris Prater said.
Further east, flash floods brought thick debris flows that cut off access to two towns. About 1,500 residents of Oak Glen, and another 1,000 residents of Forest Falls in the San Bernardino Mountains were unable to get out because the roads were covered with mud, rock and debris, authorities said.
The stranded include 500 children and adults who had arrived at a Forest Falls campground Sunday morning.
"Our concern is that they're isolated at that campground and no longer have access out of the mountain," Kyle Hauducoeur, another county fire spokesman, said.
