Thunderstorms and heavy rain doused Southern California Sunday evening, and some of those who ignored the flash flood warnings issued by the National Weather Service fell victim to fast-moving floodwaters and debris flows.
In addition to the rain brought on by the remnants of Tropical Storm Kay — between 1 and 2 inches in some areas — up to 2 more inches were expected under particularly heavy storm cells, creating “life-threatening” flash floods, the NWS said.
Reports of road closures and trapped motorists began pouring in Sunday evening.
In Los Angeles County, a mudslide closed Lake Hughes Road three miles south of Elizabeth Lake Road in Lake Hughes, according to the county’s Public Works Department.
“Motorists are advised to plan ahead and avoid the area pending updates on road conditions,” the department added.
Video footage from San Bernardino showed numerous cars attempting to travel on flood-covered streets, though some vehicles ended up disabled or trapped, with their flashers indicating their inability to move.
In Castaic Canyons, a mudflow trapped multiple cars, and the Los Angeles County Fire Department stepped in to assist.
Due to the flooding, Chaffey College has canceled in-person classes and appointments at the Rancho campus for Monday.
California State University San Bernardino‘s main campus and the Palm Desert Campus will also be closed Monday “due to extensive flooding.”
