The southbound lanes shut down Sunday night at Grapevine Road, reported ABC 30. The northbound lanes closed near Highway 38, Caltrans reported. Caltrans officials say they do not have an estimated time for reopening. “The Grapevine is closed due to dangerous conditions. Caltrans is working hard to make it safe. We will open it as soon as possible,” California Highway Patrol Grapevine Tejon said via social media. Earlier Sunday, the National Weather Service said Southern California was expected to see scattered showers and snow at elevations as low as 3,500 feet. Motorists were urged to use caution on mountain passes. Also, the latest in a series of storms dusted Northern California beaches with snow and caused whiteout conditions on mountain roads, closing a major highway, the Associated Press reported.
