BREAKING: One Dead After California Flash Flooding

Flash flooding has claimed the life of one person after heavy rains fell Sunday in San Bernardino County, California, county officials said.

The person was in a vehicle that was swept away by flood waters in the Mount Baldy area of the county, ABC7 News in Los Angeles reported on its website.

More than 4,000 people were stranded in the Oak Glen and Forest Falls areas as a result of the flooding.

Numerous roads were flooded near Barstow, Adelanto, Daggett and Victorville, with a number of them being closed due to flooding, the California Highway Patrol reported on its website.

San Bernardino County officials were assisting to provide food and shelter to some of the affected residents and campers in their area.

The rains were enhanced by monsoonal moisture flowing into the Southwest United States, Meteorologist Brian Lada said.

More than 2 inches of rain fell in Oak Glen, and 3.2 inches fell at Twin Peaks, Lada said.

"Dry weather can be expected on Monday for the Oak Glen area as the moisture associated with Sunday's rain and thunderstorms shifts to the north and east," he said.
