A major storm packing a triple threat Tuesday dumped more than a foot of new snow in the Sierra Nevada, unleashed heavy rain that triggered flooding and mudslides in the valleys around Reno and Carson City, and pushed potentially damaging winds across much of western Nevada.

The National Weather Service issued avalanche, flooding and high wind warnings up and down the eastern front of the mountains.

Classes were delayed two hours at some schools around Lake Tahoe, where more than a foot of snow was reported at ski resorts.
