San Diego got soaked by a heavy winter storm over the weekend, and snow fell on the mountains above Pine Valley.
More than 3 inches of rain fell across wide sections of East County, according to the National Weather Service. Totals included 3.3 inches near Dulzura and at Otay Mountain, and 3.2 inches at both the Cameron Fire Station and at Boulevard.
Falling snow means vehicles need chains to navigate Sunrise Highway into the Laguna Mountains, north of Interstate 8, according to Cal Fire Captain Mike Mohler. He said he is discouraging people from driving up the mountain.
More than a foot of snow had fallen at the highest elevations on Mount Laguna, according to National Weather Service San Diego.
Walker said roads would be closed, and chain requirements would be in effect on Sunrise Highway, for most of the day.
