Winter storm could dump up to 20 inches of snow on parts of East Idaho

March 6, 2017 GMT

By Journal StaffThe winter storm that began dumping snow on East Idaho Sunday morning could continue through at least Wednesday.

Some areas of East Idaho could receive up to 20 inches of snow Sunday night through Wednesday night and the National Weather Service has issued a winter weather advisory for much of the region because of the storm. The snow could keep falling in some parts of East Idaho through the rest of the week.

A wind advisory calling for gusts of over 45 mph has also been declared in East Idaho, with the most powerful winds expected Sunday night until Tuesday morning. The high winds will create blowing and drifting snow that will make for hazardous driving conditions.

The weather service stated: “Be prepared for snow covered roads and limited visibility, and use caution while driving.”

The gusts are expected to make driving on Highways 20, 26 and 33 and Interstate 84 especially hazardous.

But an even greater threat from the storm will likely be the snow.

Higher elevation areas such as Island Park, Driggs, Victor, Palisades, Wayan and Georgetown could receive up to 20 inches of snow Sunday night through Wednesday night.

Soda Springs, Grace, Bancroft, Bone, Ashton, Paris, Montpelier and St. Charles could all receive a foot of snow during that same time frame.

Six to nine inches of snow could fall Sunday night through Wednesday night in Lava Hot Springs, Inkom, Thatcher, Preston, Weston, Dayton, Franklin, Malad, Downey, Swanlake, Arimo and McCammon.

The rest of East Idaho — including St. Anthony, Pocatello, Chubbuck, Rockland, Arbon, Idaho Falls, Ammon, American Falls, Aberdeen, Fort Hall, Rexburg, Dubois, Spencer, Rigby, Roberts, Ucon, Blackfoot, Firth, Malta, Burley, Rupert, Atomic City, Craters of the Moon, Arco and Shelley — will likely see a rain-snow mix with one to four inches of snow accumulation Sunday night through Wednesday night.

The only other part of Idaho with storm-related warnings as of Sunday night was south central Idaho, where a wind advisory remains in effect until Tuesday morning.

The storm has triggered hazardous weather alerts, winter weather advisories and/or winter storm warnings in all of the states surrounding Idaho.
