More than 15 inches of snow fell in parts of coastal California and up to 107 inches of snow fell in the Sierra Nevada mountains. That’s 9 feet of snow, in just a few days.
Heavy rain caused mudslides that buried homes, closed roads and prompted evacuations. In the mountains, several interstates had to be shut down for a time due to the heavy snow.
As the storm moves east, 21 states — from the Dakotas to North Carolina — are on alert for heavy snow and a lingering Arctic blast.
A winter storm warning has been issued for Chicago, where heavy snow is expected from Saturday afternoon into Sunday.
Chicago will see 5 to 9 inches of snow due to the storm, while Washington, D.C., will see 4 to 8, Philadelphia will see 5 to 11. New York City will see 6 to 10 inches. These totals may change over the weekend.
