California officials are urging holiday travelers to avoid the roads on Christmas Eve and Christmas Day. A series of powerful winter storms is expected to douse California with relentless rain, heavy winds, and snow this week. Much of the state will see heavy rains and gusts that could lead to flooding, mudslides and rockslides. The Sacramento Valley and San Francisco Bay Area are under flood and high wind warnings through Friday. The Sierra Nevada will see heavy snow and strong winds, making travel nearly impossible. Southern California could see its wettest Christmas in years and warned about mudslides and debris flows. Some 380 particularly vulnerable households were ordered to leave.
