A massive winter storm was moving across much of the U.S. Wednesday, leaving dangerous ice and heavy snow in its wake.
The storm also brought fierce winds and bitter cold temperatures to the Upper Midwest.
Forecasters predicted at least a foot of snow could fall in Illinois, Wisconsin and Iowa.
The National Weather Service has warned of "extremely dangerous blizzard conditions." Wind gusts of up to 50 mph could result in snow drifts of up to 8 to 15 feet.
"Anybody traveling morning is really taking a huge risk I would say - a risk of being stranded and not having anybody be able to help you for 6 or 12 hours, probably," said Karl Jungbluth, a weather service meteorologist in Johnston, Iowa.
More than 20 inches of snow fell near Flagstaff, Arizona.
In North Dakota temperatures dropped to minus 14 degrees.
"It's getting worse. The farther north you go. The worse it gets," said Mike Caplan, meteorologist for television station WLS. "You're going to have blizzard conditions, even after the precipitation stops falling from the clouds. You're going to have some snow on the ground that's going to wind whipped at 40-50 miles per hour."
Eight states have now issued blizzard warning and at least five deaths have been blamed on the storms so far.
Bone-chilling wind gusts have also invaded New England, where residents may face up to a foot of snow by Wednesday afternoon.
The storm, which pounded the West with rain, wind and snow earlier this week, may affect as much as two-thirds of the country by the time it moves off the Maine coast Thursday night, said Jim Lee, a meteorologist with the National Weather Service in Des Moines.
"It's a monster of a storm," Lee said.
