BISMARCK, N.D., April 15 (UPI) -- Deep snowdrifts made roads across North Dakota impassable as Colorado prepared for severe weather that could cause similar disruptions, officials say.
Sections of two interstates and a major highway in North Dakota have been closed because of zero visibility and drifting snow, the Bismarck Tribune reported Sunday.
While the Highway Patrol had received reports of "multiple" vehicles off the road west of Mandan and accidents involving property damage, Sgt. Steven Fischer said they were not aware of any serious injuries.
Bismarck police reported being able to patrol only in four-wheel-drive vehicles because of the high drifts.
By 7 p.m. Sunday, Bismarck meteorologists said 15.8 inches of snow had fallen at the airport.
In the northern Colorado cities of Boulder and Fort Collins, rain was predicted to change to snow, causing accumulations of 1 to 2 feet from the second major storm in recent weeks, Accuweather.com reported.
North of Fort Collins, Interstate 25 was closed Monday morning by the adverse weather, which included blowing snow that reduced visibility, The Denver Post reported.
More than 200 snowplows had been put into service Monday by the Colorado Department of Transportation, with 120 along the Front Plains and eastern plains and 60 in the northern mountains.
As much as 2 inches per hour could fall across the state, with wind gusts of 30-40 mph creating major travel disruptions.
