LOS ANGELES (FOX 11) - The second round of a fall storm dumped snow and rain that jammed traffic on Southern California highways and loosened hillsides in wildfire burn areas on Thursday.
At least one vehicle got stuck in a mudslide that shut down Pacific Coast Highway and surrounding roads in and around Malibu neighborhoods charred by last month's destructive fire.
Nobody was hurt when a Southwest Airlines plane from Oakland skidded off a wet runway as it landed during downpours at Hollywood Burbank Airport north of Los Angeles. The plane came to a stop in a graded area designed to slow aircraft that overshoot the runway, the Federal Aviation Administration said.
Cars and trucks slid in lanes amid heavy snow that forced the closure of Interstate 5 in the Grapevine area between Los Angeles and the San Joaquin Valley.
The shutdown along the key north-south route was expected to cause backups for miles, transportation officials warned.
Drivers were urged to use caution on mountain passes, where up to 6 feet of snow was predicted at higher elevations.
Closer to sea level, the storm dumped rain that flooded highways and caused nightmare traffic conditions for commuters. A portion of southbound State Route 170 in Los Angeles was shut down after mud flowed onto the roadway.
Rocks and debris flowed through a Malibu canyon community that saw homes burned in November and mudslides during thunderstorms last week. City officials reported no injuries and no major property damage.
Mandatory evacuations were ordered for parts of Lake Elsinore in the Holy Fire burn area: Amorose, Alberhill, Glen Ivy A, Glen Ivy B, Glen Eden, Grace, Horsethief A, Laguna A, Matri, McVicker A, Rice, Withrow A.
The National Weather Service extended flood warnings and advisories into late morning as the storm intensified, dropping up to 1/3 of an inch of rain in a half-hour in some areas.
The system was expected to linger for much of the day before dissipating early Friday.
