WINTER WEATHER ADVISORIES DECLARED: Storm forecast to blanket all of East Idaho with snow

December 12, 2018 GMT

East Idaho is forecast to be hit by a significant winter storm this week that will make driving in the region difficult if not hazardous.

The National Weather Service has issued multiple winter weather advisories covering all of East Idaho warning the public about the snowstorm, which will hit Tuesday night and continue through Wednesday afternoon.

The weather service is telling East Idahoans to expect snow-covered roads, high winds and limited visibility because of the storm. Motorists should use caution especially during the Wednesday morning commute because of the expected difficult driving conditions.

The weather service said East Idaho’s lower elevation areas could receive 3 to 4 inches of snow Tuesday night through Wednesday afternoon but it’s possible much more snow could fall. These lower elevation areas include Pocatello, Chubbuck, Fort Hall, Preston, Franklin, Malad, Holbrook, Malta, Albion, Raft River, American Falls, Aberdeen, Burley, Rupert, Heyburn, Blackfoot, Shelley, Firth, Atomic City, Idaho Falls, Ammon, Rigby and Rexburg.

The higher elevation Dubois, Spencer, Thatcher, Inkom, Arimo, McCammon, Downey, Swanlake, Lava Hot Springs, Rockland, Arbon, Arco, City of Rocks and Craters of the Moon areas could also receive 3 to 4 inches of snow Tuesday night through Wednesday afternoon, though it’s possible much more snow could fall on these places as well, the weather service reported.

East Idaho’s other higher elevation areas including Island Park, St. Anthony, Ashton, Driggs, Victor, Palisades, Swan Valley, Bone, Henry, Wayan, Soda Springs, Bancroft, Grace, Montpelier, St. Charles, Paris and Georgetown could receive 6 to 8 inches of snow Tuesday night through Wednesday afternoon, but again it’s possible much more could fall, according to the weather service.

The storm is also expected to hit most of the rest of Idaho. The central Idaho mountains including Stanley, Sun Valley and Ketchum are under a winter weather advisory calling for maximum snowfall amounts of 8 to 14 inches.

Areas north of Boise and Mountain Home are also under winter weather advisories and most of North Idaho is under multiple winter storm warnings.

Outside of Idaho the snowstorm has triggered blizzard warnings, winter storm warnings, winter weather advisories and high wind warnings in Montana; winter storm warnings, winter weather advisories and wind advisories in Washington state; winter weather and wind advisories in Oregon; winter storm warnings, winter weather advisories, high wind warnings and special weather alerts in Wyoming; wind advisories in Nevada; and all of Utah is under a hazardous weather warning.
