LOS ANGELES — Rains pounded the Los Angeles area as a weekend storm passed from the Pacific Ocean into Southern California, flooding streets and highways and prompting concerns about possible landslides.
The National Weather Service issued a flood advisory and winter weather advisory Sunday for areas around Los Angeles County, including foothill communities north of the city where hillsides were stripped by wildfires two years ago.
Forecasters predicted several hours of downpours followed by scattered showers into the evening. Some areas could see up to 2 inches of rain. The heaviest rains will be centered in the Santa Monica Mountains and the foothills of the San Gabriel Mountains, forecasters said.
By noon, more than an inch of rain had fallen at Sepulveda Pass, which links the Los Angeles Basin to the San Fernando Valley.
Lanes were flooded on Interstate 10 and Highway 101 in Hollywood, and high water was reported on surface streets in the area. At Los Angeles International Airport, more than a foot of water accumulated in the northbound Sepulveda Boulevard tunnel under the southern runways, according to the fire department.
Snow was expected for mountains north and east of Los Angeles and in Santa Barbara County, with several inches possible at elevations above 4,500 feet.
Gusty winds combined with snowfall contributed to poor visibility on mountain routes, including on Interstate 5 in the Grapevine area, which saw slowed traffic but no lane closures.
Chains were required on some mountain roads near Ojai in Ventura County, where some of the heaviest downpours were reported.
More than a dozen traffic crashes Sunday were blamed on wet conditions around L.A., California Highway Patrol officer Ed Jacobs said.
