Snow levels dropped below 3,000 feet, covering mountain communities and creating slick road conditions along the Grapevine section of Interstate 5, prompting California Highway Patrol to escort traffic in the area in the evening. Residents in the area are still cautious a freeway shutdown could happen later.
Shortly after 9 p.m. Monday, the 5 through the Grapevine was fully closed to traffic in both directions due to snow on the road, Caltrans said. The major thoroughfare reopened Tuesday around 5 a.m.
Most of the heavy rain fell in the early to midmorning hours, making for a slippery commute to work. Dry weather and slightly warmer temperatures return Tuesday and remain for the rest of the week.
A slight chance of showers was forecast this afternoon, with a wind advisory in effect in the Los Angeles area through 7 p.m., with temperatures maxing out in the mid-50s.
