MOUNT SHASTA (CBS/AP) — Officials have closed a section of Interstate 5 in Northern California after a storm dropped heavy snow and led to cars and trucks sliding on the slippery roadway.

The California Highway Patrol on Friday said the highway was closed 10 miles north of Redding in Shasta County, and are advising drivers to use alternate routes.

The National Weather Service said that the storm dropped a foot of snow in some areas, and prompted an avalanche warning for Mt. Shasta.
