A powerful storm Saturday ushered in the new year in California, with much of the state witnessing drenching rain or heavy snowfall that was snarling traffic and closing highways.
In the high Sierra Nevada, as much as 2 feet (0.6 meters) of snow could accumulate Saturday into early Sunday. The National Weather Service in Sacramento warned about hazardous driving conditions and posted photos on Twitter showing traffic on snow-covered mountain passes, where vehicles were required to have chains or four-wheel drive.
