"California Braces for Heavy Rainfall and Flooding Ahead of Christmas"

Southern California is expected to experience heavy rain, thunderstorms, and flooding before Christmas as a slow-moving winter storm system moves through the region. The storm, which is cut off from the Pacific jet stream, is forecasted to bring heavy rain and potential flooding to areas including San Luis Obispo, Santa Barbara, Ventura, and Los Angeles counties. Residents are advised to be cautious of debris flows, flash flooding, and overflowing rivers. The storm is expected to gradually move south, with showers continuing until Friday, followed by gusty winds on Saturday and slightly warmer temperatures on Sunday. Snow is not expected below the 7,500-foot mark.
