California storm closes roads, triggers flash flood warnings. Here's how long it will last

"Californians looking to resume their weekly commute Tuesday awoke to see several major roads closed after heavy rains drenched much the state Monday - with the expected precipitation far from over. Among the closures was a section of Highway 1 through Big Sur, which state officials just weeks ago celebrated reopening for the first time in three years. The road closed Monday after rockslides left "debris in the roadway at multiple locations," according to the California Department of Transportation."

"And more torrential rains are expected, with much of Southern California still under a flood watch, according to the National Weather Service. A wave of heavy showers and thunderstorms are forecast to sweep across the region Tuesday afternoon, "bringing the risk for flash flooding, rock and mud slides, and burn-scar debris flows across the flood watch area," the advisory said. It is in effect for most of southwest California, including Los Angeles, Ventura, San Luis Obispo and Santa Barbara counties."

"Much of the area's mountains are also under a winter storm warning, with heavy snow possible Tuesday evening through Thursday, according to the weather service. That includes the Grapevine along Interstate 5 and the Highway 14 corridor, where up to 4 inches of snow is possible. Higher elevations could see anywhere from 4 to 12 inches. 🚩 TOPANGA CANYON BOULEVARD 🚩Topanga Canyon Blvd (State Route 27) closed in both directions from PCH to Grand View Dr until further notice due to storms. Multiple locations within the closure have mud & debris slides.👇@CaltransDist7 Maintenance & GeoTech teams on scene."

Heavy rains closed several major California roads and prompted continued closures Tuesday morning. A section of Highway 1 through Big Sur shut after rockslides deposited "debris in the roadway at multiple locations," and Topanga Canyon Road remained closed after crews responded to at least eight debris flows. Forecasters issued flood watches across much of Southern California, warning of flash flooding, rock and mud slides, and burn-scar debris flows as another wave of heavy showers and thunderstorms moves through. Mountain areas faced winter storm warnings with heavy snow possible, including 4 inches near the Grapevine and 4–12 inches at higher elevations.
