“Hazardous travel is expected, especially through the mountains,” according to the National Weather Service.

A winter storm warning will be in effect through 6 p.m. Wednesday in the San Diego County mountains, with snow accumulating up to a foot in some areas, with as much as 18 inches on higher peaks.
