Wild weather brings flooding to Southern Calif.

LOS ANGELES (AP) — Monsoonal moisture and warm temperatures were expected to bring more thunderstorms to the desert and mountain areas of Southern California on Monday after a round of wild weather that caused flash flooding and left several thousand homes without power.

Thunderstorms dumped rain and caused flash flooding on Sunday in northern Los Angeles County, while lightning strikes sparked a small fire in the San Bernardino National Forest.

Strong winds produced a blinding dust storm in the Borrego Springs area and knocked down power lines that forced the closure of a portion of Interstate 10 near Palm Springs for a couple of hours.

The wind gusts also downed trees in inland San Diego County and cause a power outage to about 4,000 homes in San Bernardino County.

A Temecula woman was killed Sunday after she lost control of her pickup truck on a freeway in heavy rain.

The National Weather Service issued a flash flood warning Monday for most Southern California mountain and desert areas. Heavy downpours were expected in some areas because storm will be slow-moving due to weaker winds.
