DAILY FORECAST: It’s gross out there. Seriously.
IDAHO FALLS — Eastern Idaho is looking at a mixture of snow and rain for Tuesday, April 25.
All of western Wyoming and southern Montana are under a winter weather advisory or winter weather warning. Between 6 and 12 inches of snow is expected throughout the region, which is creating poor road conditions.
The rain is causing the Portneuf River to rise again. The river, which is more than a foot above flood stage, is measuring at 9.7 feet. Minor flooding is occurring along its banks. The river is expected to rise above 10.1 feet by Thursday morning causing moderate flooding in the surrounding area.
A flood advisory is still in effect for the Bear River in Bear Lake County. The river, and surrounding streams remain elevated and are slightly above their banks from Montpelier to the Wyoming State Line. Some minor field and dirt road flooding is occurring near Pegram and Dingle.
No major road closures have been reported as of 8 a.m. Tuesday.
Difficult driving conditions are being reported on U.S. Highway 20 between Island Park and West Yellowstone, Montana. The roads are covered in snow.
Packed snow, icy and gusty winds are being reported on Interstate 15 between Dubois and Lima, Montana.
Winter weather conditions are also creating hazards on Idaho Highway 31 between Lamont and Tetonia, Idaho Highway 33 between Tetonia and the Wyoming State Line, U.S. Highway 30 between Georgetown and the Wyoming State Line, and U.S. Highway 89 between Montpelier and the Wyoming State Line.
