Flood advisories and warnings are up for parts of Southern California as a vigorous storm system from the Pacific Ocean sweeps across the region. The rain is welcome news given the drought conditions, but the intense downpours could prove disruptive.

The National Weather Service is predicting widespread rainfall of 2 to 4 inches through Monday in much of southwest California, with locally higher amounts possible. Snowfall of 8 to 18 inches is predicted in the mountains above 6,000 feet, where winter storm warnings are in effect.
