LOS ANGELES, Calif. – A strong Pacific storm will sweep across Southern California from Monday night through Wednesday, bringing the season’s first widespread rain, gusty winds, and cooler temperatures. Forecasters warn of minor flooding, travel slowdowns, and isolated power outages across Los Angeles, Ventura, Santa Barbara, and San Luis Obispo counties.
According to the National Weather Service in Oxnard, 6 to 12 hours of steady rainfall are expected, with peak intensity Tuesday between 3 a.m. and 9 p.m. Totals may range from 0.5 to 1.5 inches in coastal and valley areas, with up to 4 inches possible in mountain zones. South winds could gust between 20 and 40 mph, raising the risk of downed branches and slick roads during the Tuesday morning and evening commutes.
Forecasters noted that flash flooding and debris flows remain a low but nonzero threat, especially near recent burn scars. Mariners and beachgoers should also prepare for 6- to 10-foot waves and steep seas through early Sunday before the rain arrives. Elevated fire danger persists inland until moisture increases Monday night.
Residents are urged to secure outdoor furniture, clear storm drains, and delay nonessential travel during heavy rain periods. Drivers should allow extra time on I-5, US-101, and coastal routes where ponding is likely. Temperatures will drop sharply behind the front, with highs only in the 60s to near 70 midweek.
