MICHIGAN — A massive snow cover in the mountains of Montana has closed highways and highways leading to the rest of the state, and has been the worst in years for air quality.
The state’s Department of Transportation said it has shut down more than a dozen roads in the state since Wednesday, with one in the southbound lanes being closed for more than two hours and another in the eastbound lanes for about 15 minutes.
The closure has also led to the closure of Montana Interstate 5.
The National Weather Service said there has been a 40 percent increase in the amount of snow that fell in the central and southern regions of the United States in the last week.
The Weather Service also said that overnight temperatures in the western portion of the Great Plains are expected to climb into the 60s to 70s in some areas, and that temperatures will remain at those temperatures through the weekend.
The snow cover also caused severe road closures and reduced visibility.
The National Park Service said the snow is also causing problems with the Yellowstone grizzly bear population in Yellowstone National Park, with many areas experiencing the death of bears that normally live in areas near the park’s northern boundary.
