With snow falling along the Grapevine, it was closed Sunday evening following multiple collisions as forecasters advised the public to avoid travel on high elevations amid a winter weather advisory effective until 3 a.m. Monday for Los Angeles and Ventura county mountains.
Earlier on Sunday, the National Weather Service predicted a cold weather system to move across Southern California through the night. Snow levels were expected to fall to 2000 to 2,500 feet.
"Motorists traveling through the I-5 corridor and other mountain highways should be prepared for hazardous winter driving conditions due to snow and ice covered roads, reduced visibility, gusty winds and blowing snow," NWS said. "Low elevation mountain passes will be affected by snow and ice, including the Interstate 5 near the Grapevine, along with Highways 14, 33 and 166."
California Highway Patrol officials said the the Grapevine was closed in a tweet at 6:13 p.m. Officials later said eastbound Lake Hughes Road to northbound Ridge Route to Sr-138 was expected to be blocked.
Caltrans echoed forecasters' warnings. Agency officials said travelers with campers, trailers or permit loads should not pass through the 5 Freeway three miles north of the 126 junction at Parker Road to the L.A.-Kern County line.
Inclement weather disrupted traffic across Southern California freeways and roads over the past week. Many motorists headed to the mountains for the Presidents Day holiday weekend have had to turn around due to ski and road closures.
