A big winter storm is headed for the Sierra and much of northern Nevada, with snowfall possible on valley floors and blizzard conditions expected in the mountains by Thursday.
As much as 4 feet of new snow is possible in the upper elevations around Lake Tahoe into Thursday.
Weather watches, including an Avalance Watch, are set for the Tahoe area into Thursday night.
The weather service says travel could be difficult to impossible later Wednesday through Thursday with periods of white-out conditions possible.
If you're planning on traveling to Tahoe, it's advised to wait until the storm is over.
