Blizzard brings 10 feet of snow to California and Nevada mountains, causing dangerous travel conditions

California authorities closed a 100-mile stretch of Interstate 80 on March 1 due to spin-outs, high winds, and low visibility. No estimated time for reopening was given. A blizzard is shutting down the central Sierra region with up to 10 feet (3 meters) of snow expected in some areas and high to extreme avalanche danger. The most powerful storm of the season is hitting the Sierra Nevada mountains, bringing heavy snow, reduced visibilities, toppled power lines, and hurricane-force winds over 75 miles per hour. About a million people are under blizzard warnings in the Mountain West, with another 6 million under winter weather alerts across the region. Visibility has already plummeted to near-zero in some areas, making travel impossible. In the highest peaks of the Sierra Nevada, winds have gusted over 140 mph and topped 150 mph on Friday as blizzard conditions intensified. Nearly 2 feet of snow has already fallen with extreme snowfall expected to continue.
