Blizzard conditions in parts of US make travel ‘very dangerous if not impossible’

Weather service issued a blizzard warning for parts of North Dakota, South Dakota and Montana, with expected snow up to 15in and winds up to 55mph

It’ll be a white but slick and messy Christmas for the northern plains and some western states.

Most of the Dakotas and south-west Minnesota were turning into an “icy, slippery mess” due to freezing rain Sunday morning that was expected change into snow later in the day when temperatures fell, according to National Weather Service meteorologist Greg Gust in Grand Forks, North Dakota.

His advice to holiday travelers: “Stay put.”

“Between the ice and snow, and winds howling like crazy, there will be nothing moving” until late afternoon Monday, he said. “Then it’s dig-out time.”

A blizzard warning was in effect for most of North Dakota, western South Dakota and a small section of eastern Montana through Monday, with expected snow totals of 8in to 15in and winds up to 55 mph.

Up to a ½ inch of ice could accumulate in central Minnesota, and the weather service has said anyone who “must travel” should have an extra flashlight, food and water.

Rain was due to move through parts of Kansas, Missouri, Texas, Oklahoma and Nebraska on Sunday.
