GLENDORA (CBSLA.com) - The storm that dumped as much as four inches of rain over the eastern San Gabriel Mountains Sunday left at least one person dead and many more stranded and needing rescue.
The fierce storm was quick - over in less than an hour - but its swiftness and suddenness caught many off guard.
One person was reportedly killed when their car washed into a river near Mt. Baldy. It was unclear if the person died from drowning or exposure.
People were stranded by mudslides and rising flood water.
Authorities said the worst of the rain damage occurred near the communities of Mt. Baldy and Forest Falls in San Bernardino County.
Cars were reportedly stranded or washed away, massive debris fields blocked roads, campers were stranded and at least one person had to be rescued from rising flood waters.
Officials also reported a large rock slide that covered all lanes of the Angeles Crest Highway at mile marker 66, near Little Jimmy Road, around 4:15 p.m.
A slide near the Mt. Baldy Fire Station, reported just after 5:15 p.m., closed Mt. Baldy Road, according to the CHP.
Four to five people and a dog became stranded by raging flood water and were unable to reach their vehicle, Sgt. Rebecca Rodriguez of the Los Angeles County Sheriff's San Dimas Station said. They were airlifted to safety by a sheriff's helicopter about 5:30 p.m., she said.
An overturned vehicle was found near the intersection of Bear Creek and Mt. Baldy roads, but no one was inside, Rodriguez said.
