The arrival of a large arctic air mass from Canada was delivering an “axis of heavy snow” to many parts of the northern US, the National Weather Service (NWS) reported on Wednesday.

The snow will continue to move east across the Northern Plains into the Upper Midwest and Great Lakes today.

More than a foot of snowfall is likely from South Dakota heading east throught southern Minnesota, northern Wisconsin, and the Upper Peninsula and northern Lower Peninsula of Michigan, NWS reported.

Southern Minnesota could see two feet of snow, forecasters said, amid dangerous blizzard conditions on roads and possible power outages.

Snow will start making an appearance in the Northeast and New England late on Wednesday into Thursday.

An estimated four to eight inches of snow is forecast from Upstate New York into central New England. Over a foot is possible at higher elevations in New York’s Adirondacks and the Green and White Mountains of New Hampshire and Vermont.

Three killed in avalanche in Cascade Mountains as heavy snow blocks rescuers

17:49 , Louise Boyle

Heavy snowfall and high winds on Tuesday kept searchers away from a remote, jagged peak in Washington’s Cascade Mountains, where an avalanche killed three climbers from the northeastern US over the weekend.

The slide struck Sunday as a group of six climbers were ascending a steep, snow-packed gulley on the 8,705-foot Colchuck Peak, about 70 miles east of Seattle in the Alpine Lakes Wilderness, Chelan County sheriff’s Sgt. Jason Reinfeld said Tuesday.

Four of the climbers were swept about 500 feet down the slope. One of the four survived, a 56-year-old man from New York, and despite some injuries he was able to confirm that the other three were killed before working his way back to their base camp at Colchuck Lake, Mr Reinfeld said.
