Flooding and snow hit the West while parts of the South could see record-breaking warm temperatures on Christmas

Residents along the West Coast can expect to see flash flooding throughout the holiday weekend, while snow will pile up in the mountains. The National Weather Service warns it'll be a "wet, wintry, windy, and a White Christmas for some in the West with hazardous travel conditions in mountainous terrain." 

Storms have already washed out or damaged parts of some mountain roadways in Southern California.

The National Weather Service has issued a flood advisory until 12:30 a.m. tonight, local time, for western Los Angeles County, with urban and small stream flooding possible, as well as a flood advisory throughout parts of Arizona until Friday afternoon.
