Monday night, the CHP shut down traffic through the Grapevine for more than an hour as the storm began.
CHP officers shut down the southbound side of the 5 Freeway at Grapevine Road in Kern County and the northbound side at Parker Road in Castaic.
The CHP started holding traffic around 5 p.m. and then implemented a full shutdown by about 5:45 p.m. Drivers who were stuck in the area were being escorted off the freeway.
But conditions later cleared up and CHP officers had both sides of the freeway open again by 8 p.m.
Drivers who have to use the Tejon Pass are advised to use caution and expect delays as the rain and snow continue over the next several days. At least a foot or more of snow is expected in mountain communities, while the lower-lying communities could see several inches of rain Monday, Tuesday and Wednesday.
