LOS ANGELES (AP) — The Latest on Southern California thunderstorms (all times local):

2:05 p.m.

Mudslides, debris flows and flash flooding are occurring in Southern California mountains and deserts as thunderstorms move through the region.

The San Bernardino County Fire Department tweets that numerous vehicles are stranded Thursday afternoon in Lucerne Valley due to significant flow of water and debris on State Route 18. The department adds that no rescues are required.

Mud and debris have also closed Valley of the Falls Drive in the San Bernardino National Forest.

The National Weather Service has issued severe thunderstorm and flash-flood warnings in the region.

Thunderstorms spawned by monsoonal flow have shattered some weather records this week.

In Campo in southeastern San Diego County, no rain had ever been recorded on a July 11 until this year, when 1.18 inches (30 millimeters) fell. In Palm Springs, Wednesday’s 1.08 inches (27.4 millimeters) of rain destroyed the old record of 0.03 inch (0.76 millimeter) set in 1999.


12:32 p.m.

Thunderstorms are again dumping heavy rain in some mountain and desert areas of Southern California.

The National Weather Service issued a flash flood warning from late morning through midafternoon Thursday for San Bernardino and Riverside counties.

Forecasters say rainfall rates could reach up to three-quarters of an inch (190 centimeters) an hour.

Deluges also hit the area Wednesday due to monsoonal flow.

Along the Southern California coast, meanwhile, the weather service has issued advisories for minor coastal flooding during high tides through Saturday.
