LOS ANGELES (AP) — A powerful storm spread more rain across California on Thursday, flooding streets and threatening to unleash mud and debris flows into communities near areas burned bare by wildfires. The National Weather Service said there were numerous reports of street flooding in the Central Valley cities of Fresno and Clovis. A flood warning was issued for areas east and south of Sacramento as rain caused the lower San Joaquin River system to rise along the western flank of the Sierra Nevada.
