Heavy snow on Thursday, March 1, shut down I-80 through the Sierra Nevada mountains in California and Nevada. The National Weather Service issued a blizzard warning through Friday morning, saying travel will be dangerous.

Whiteout conditions, wind chills and drifting snow were expected during the storm. “Even a short walk could be deadly in these conditions,” the weather service tweeted. Up to five feet of snow was expected in the higher elevations.
