Our weeklong blast of arctic air has done more than ice up roads and highways; some of the region's rivers are also reporting ice jams, increasing flood risks.
This morning's Missoulian reports that "a milelong ice jam was moving down the Salmon River through the town of Salmon on Monday," backing up water and putting a U.S. Highway 93 bridge in town at risk of minor flooding.
“We’ve been barely making it out of the teens, and after several days like that, it starts to build up the ice,” National Weather Service meteorologist Luke Robinson told the Missoulian. “But Salmon has been down to 15 below zero, and stayed at 5 below for several days.”
The Salmon area is expecting highs for the rest of the week in the upper teens, but overnight lows approaching 5 below zero until Thursday, Jan. 17.
