LOS ANGELES (CBSLA.com) — With temperatures are expected to fall to the freezing point over the next few nights, the Union Rescue Mission is looking to provide more warm beds to people on the streets.

Health officials have issued a winter weather warning for Southern California mountains and valleys as an extremely cold winter storm approaches. The storm dipping into the region from Canada is forecast to bring rain and snow to the area Tuesday afternoon through Wednesday, and snow levels could drop to around the 2,000-foot level.
