"Winter Storm Paralyzes California and Nevada, Leaving Thousands Without Power"

A powerful blizzard has hit the Sierra Nevada, shutting down a long stretch of Interstate-80 in California and leaving tens of thousands without power. Up to 10 feet of snow is expected in some areas, with blizzard conditions and high avalanche danger predicted. The storm has caused a tornado in Madera County and led to the closure of ski resorts. More than 25 million people are under winter weather alerts as the storm continues to wallop the area.
