HIGHLAND (CBSLA.com) — Flash flood watches were expected to be in effect until 11 p.m. Friday for Riverside and San Bernardino counties along with a flood watch for Los Angeles and Ventura counties.
The National Weather Service (NWS) also extended a flash flood warning, which expired at 7:15 p.m., for parts of San Bernardino and Riverside counties.
In Moreno Valley, near Fox and Poppet Flats roads, a RV and trailer campground was inundated by flood waters just after 5 p.m. Aerial footage showed people stranded with firefighters reportedly responding to the scene and initiating rescues.
“The cleanup out here is continuing at this point. They have some heavy machinery cleaning up some of the mud that flowed right through this RV and trailer campground,” reported Sky2’s Gil Leyvas.
Friday’s warnings and watches were issued a day after a storm knocked out power to 10,000 customers in Riverside. It also submerged streets, uprooted trees and flooded several homes, as well as a local fire station.
Emergency officials advised residents to stay indoors should it rain heavily and motorists were advised to drive cautiously due to potential flooding and tree branches in the roadways.
Additionally, the city has operated its emergency operations center in anticipation of more storms.
