Second round of major winter storm to bring snow and danger to large parts of U.S.

A second round of snow began to fall in Minnesota on Wednesday as forecasters warned of a major winter storm that could make travel dangerous for wide stretches of the country.
The Twin Cities of Minneapolis and St. Paul were forecast to get up to 12 more inches of snow from 6 p.m. Wednesday to 6 p.m. Thursday, the National Weather Service said, on top of the 5 inches that had already fallen.
“Minnesotans are no strangers to extreme weather, but this storm could break records,” Gov. Tim Walz said in a statement Wednesday.
More than 55 million people, from the Northern Plains to Boston and Maine and along the western U.S. coast, were under winter weather warnings or advisories Wednesday night, according to the weather service.
Blizzard warnings were in place for 2 million more, and ice storm warnings affected 8 million.
In the Los Angeles area, blizzard warnings were in effect for the mountains. The last time that appears to have happened was in 1989, the weather service in Oxnard said.
A series of low-pressure waves traversing an Arctic cold front was pushing the heavy snow and blizzard conditions to the Plains and the Midwest, the weather service said, with major disruptions to travel likely.
“Fortunately our plane got in, but it looked like there were 90% of the flights getting canceled,” said Ann Viksnins, who flew in to a surprisingly empty Minneapolis airport Wednesday. “It’s just really eerie here in the airport.”
Minneapolis−Saint Paul International Airport had more than 400 cancellations Wednesday, the airport said.
Sioux Falls, South Dakota, Police Lt. Andrew Siebenborn joked to reporters that he made it “probably about 11 feet” to the end of his driveway before his squad car got stuck.
“We really aren’t even into the bad part of the storm that’s coming up, and we expect it to get a lot worse,” Siebenborn said Wednesday. He encouraged people to stay home and wait it out.
Around 8 ½ inches of snow had fallen at the city’s airport by 10 p.m. Wednesday, and the weather service expected the last round of snow to drop 1 inch an hour after midnight.
The Arizona Transportation Department closed parts of at least eight interstates or state routes Wednesday because of the winter storm. Around 3 to 6 inches of snow fell in the Flagstaff area, with winds gusting up to 50 mph, the weather service said.
The heavy snow risk in the western U.S. will be mainly in California on Thursday and Friday because of a new storm, according to the weather service.
The blizzard warning in Southern California is for the mountains in Los Angeles and Ventura counties, the weather service said, from 4 a.m. Friday to 4 p.m. Saturday. The mountains could get 5 feet of snow, it said.
