RIVERSIDE – A flash flood warning was issued today for central Riverside County as fast-moving thunderstorms over the eastern edge of the San Gorgonio Pass could produce flooding south of Interstate 10 in the Coachella Valley and in western Palm Springs, forecasters reported today.
The National Weather Service (NWS) also reported that areas within the eastern part of the Silver Fire burn area and further downstream could be impacted and result in debris flow. Heavy showers have already formed over areas scarred by the Mountain Fire which could also produce debris flow, according to the NWS.
Other locations in the weather warning include but are not limited to the Mt. San Jacinto peak, Cabazon and Highway 243.
Thunderstorms aren’t quite pushing into Palm Springs but is heading west of there, NWS forecaster Cynthia Palmer said.
Homes, campgrounds, trails and roads located along areas within or below the charred basins scorched by the recent wildfires are especially vulnerable. Motorists are urged not to drive in areas where water covers the roadways, the National Weather Service reported.
Chance of thunderstorm activity possible later today in region
SAN DIEGO & RIVERSIDE COUNTIES – There is a chance of isolated thunderstorms in the mountains and deserts in the afternoon and evening today, Sun., August 18, the National Weather Service (NWS) said.
“We’re expecting a few thunderstorms in the mountains and upper desert,” NWS forecaster Brett Albright said. “Low pressure over the coast is helping to bring in monsoonal moisture.”
Albright said temperatures are about normal for this time of year.
The forecast heading into next week is for drier conditions to prevail by Tuesday, with night and morning low clouds and clearing skies in the afternoon along the coast, Albright said.
Temperatures on Monday are expected to be in the low 70s along the coast, in the 80s to 90s in the inland valleys and mountains and in the low 100s in the deserts, NWS said.
