A blizzard warning was in effect until the middle of Christmas Day in western Montana along the eastern side of the Rocky Mountains. The National Weather Service warned Saturday that the eastern slope of Glacier National Park and the adjacent foothills and plains could see up to 8 inches of snow and winds up to 90 mph. The weather service advised traveling only in emergencies, saying it could be difficult to impossible. The Weather Service also said blowing snow will significantly reduce visibility and drifting snow could block lanes. The Weather Service also warned that travel could be treacherous further to the west in Montana and in north-central Idaho.
