Los Angeles, California – Snow and strong winds are already creating hazardous travel conditions across Southern California’s mountain areas, with impacts expected to intensify into the Monday morning commute.
According to the National Weather Service in Los Angeles/Oxnard, a Winter Weather Advisory remains in effect until 11 a.m. Monday across the Ventura County Mountains, Santa Barbara County Interior Mountains, and the San Gabriel Mountains, including the Interstate 5 corridor near the Grapevine.
Snow accumulations of up to 6 inches are expected above 6,000 feet, while wind gusts could reach 40 to 45 mph, strong enough to bring down tree branches and reduce visibility. Snow levels will drop from around 7,000 feet Sunday morning to as low as 4,500 to 5,000 feet by early Monday, increasing the coverage of wintry conditions.
Key travel routes include Interstate 5 near Tejon Pass, Highway 14, and mountain roads near Wrightwood, Mount Baldy, and Lockwood Valley. While significant accumulation is not expected directly on the Grapevine, a rain-snow mix could still create slick spots during the Monday morning commute.
Drivers should expect rapidly changing conditions, including wet roads, reduced visibility, and strong crosswinds. Officials urge motorists to slow down, use caution, and check road conditions by calling 511 before traveling through mountain areas.
The advisory remains in effect through late Monday morning, and additional updates are possible if conditions worsen.
