Dangerous conditions prompted the Montana Department of Transportation to close roads across rural Montana on Monday.

U.S. Highway 191 between Grass Range and Malta remained closed last night due to snow drifting and blowing across the road. U.S. Highway 12 from east of Miles City to the North Dakota state line and Montana Highway 7 from Wibaux to Alzada remained closed as well. Montana Highway 66 from Highway 191 to U.S. Highway 2 and Montana Highway 200 between Jordan and Brockway were reopened late Monday.

A winter storm warning remained in effect throughout northeastern Montana into late Monday night, according to the National Weather Service. In portions of western North and South Dakota, a blizzard warning was in effect through 6 a.m. today.
