A flood watch was in effect for the same timeframe in much of Riverside County, San Bernardino County and parts of San Diego County.
In the San Bernardino Mountains, storms produced road flooding in the Oak Glen area in the El Dorado fire burn scar area. in Oak Glen, Potato Canyon Road and the north side of Oak Glen Road were closed, California Highway Patrol logs showed. The roadways were affected by two feet of mud and debris, Cal Fire San Bernardino said, adding San Bernardino County Public Works was called in to address the problem.
There were also some debris slides on Highway 18 in the Big Bear area, CHP logs showed.
“The conditions for flooding are there and the system we’ve been monitoring has been slow-moving, lingering over the San Bernardino mountains for the past few hours,” said NWS meteorologist Samantha Connolly on Saturday afternoon..

Some heavy downpours are possible, according to the National Weather Service.
Despite the chance for precipitation, inland temperatures remain high in the low 90s and are approaching 100 degrees in the Antelope Valley. The warm weather will likely continue into next week, and the showers and thunderstorms are expected to taper off by Tuesday, according to Connolly.
From the beaches to downtown Los Angeles, highs will linger in the 70s to mid-80s with a slight chance of rain on Sunday.
A beach hazards statement was also issued through Wednesday afternoon at the Malibu coast and other Los Angeles County beaches, where dangerous rip currents and breaking waves are expected due to elevated surf of 3 to 6 feet.
More typical midsummer weather is expected for the balance of the week, with night through morning low clouds in coastal areas, and temperatures within a few degrees of normal, forecasters said.
