Blizzard Warning issued for Southern California mountains


A major winter storm will slam Southern California with heavy mountain snow and damaging wind gusts.

These combined conditions (snow and wind) are expected to bring blizzard conditions to the Southern California mountains in Los Angeles and Ventura counties from Friday through Saturday.

Because of the forecast of blizzard conditions, the National Weather Service issued a Blizzard Warning from 4 a.m. Friday until 4 p.m. Saturday for these mountains. Areas within the Blizzard Warning can expect winds gusting up to 75 mph along with heavy snow that will reduce visibility to near zero.
