SAN DIEGO (KGTV) -- A winter storm wreaked havoc Thursday, drenching San Diego with rain and snow and forcing the closure of Interstate 8 in East County, I-15 in the Cajon Pass, and I-5 in the Grapevine.
Snow and ice forced the California Highway Patrol to close a 50-mile stretch of I-8 in both directions between Imperial Highway (SR-98) in Ocotillo and SR-79 about 8:15 a.m. Multiple cars were stuck in the area, said CHP Officer Jim Bettencourt. U.S. Border Patrol officials assisted the CHP in closing side roads to protect travelers.
The freeway reopened about 11:30 a.m. The closure was one of several affecting travelers in Southern California.

Farther north, the California Highway Patrol shut down Interstate 5 through the Grapevine north of Los Angeles Wednesday night due to multiple stuck vehicles and heavy snowfall. There was no immediate plan to open the busy mountain thoroughfare connecting Southern California to the Central Valley. Caltrans suggested a detour of Highways 58 and 14, but added that snow was also falling in the area.
A driver was found dead inside a parked big rig in the Grapevine, KABC reported. The person's cause of death was not immediately known.
Interstate 15 was also affected through the Cajon Pass, a popular route to Las Vegas. Caltrans shut down the freeway in both directions early Thursday morning due to snow. Southbound I-15 was also closed between Baker and Primm because of the weather.
