A flash flood warning has been issued for parts of Southern California as rare September thunderstorms dump heavy pockets of rain and even hail.
The warning was issued for San Bernardino County until 5:30 p.m. The National Weather Service said up to an inch of rain has fallen as of Friday afternoon.
“Additional rainfall amounts of 0.25 to 1.25 inches are possible in the warned area.”
Some areas that could experience flash flooding include San Bernardino, Redlands, Yucaipa, Highland, Running Springs, Highway 18 between Running Springs and Big Bear, Highway 330 between San Bernardino and Running Springs, Angelus Oaks, Highway 18 between Running Springs and Skyforest and Mountain Home Village.
The low desert areas also saw thunderstorm activity, mainly in the area surrounding Palm Springs, just east of Desert Hot Springs and south of Yucca Valley.
People living in Redlands and Riverside saw rain coming down around noon.
After the recent wildfires, there is some concern about debris and mudflows.
The Los Angeles County Sheriff’s Department listed the unincorporated communities of Mount Baldy, Wrightwood, Big Pines, Agua Dulce and Santa Maria as “potentially vulnerable locations.”
Officials are urging residents in those areas to get free sandbags.
