California on alert as heavy snow and rain bring continuing danger and delays

More snow and rain fell on California on Wednesday, causing travel disruptions on mountain routes and raising the risk of debris flows from wildfire burn scars.

Major highways through the snow-blanketed Sierra Nevada remained open, but chain requirements were in effect in many areas, CBS Sacramento reported.

Caltrans said snowplows were working around the clock and urged people to avoid all but essential travel in the Sierra.
