Forecasters say the system will swirl ashore from the North Pacific and drench the region well into Thursday, possibly causing flash flooding. The rain also could cause debris flows in the areas of Los Angeles and Ventura counties that were recently hit by major wildfires.
Snow could fall as low as the 6,500-foot level, and six inches of snow could blanket mountains above 7,000 feet.
Forecasters also are expecting large surf at the coast.
