Dillon, Montana – Wet snow across southwest Montana could create hazardous travel through midafternoon Thursday.
According to the National Weather Service in Great Falls, a Winter Weather Advisory remains in effect until 3 p.m. MST Thursday for portions of Beaverhead and western Madison counties, along with nearby mountain ranges.
Forecasters say additional snow accumulations up to 2 inches are expected, with 2 to 4 inches possible near higher passes, including Chief Joseph Pass and Big Hole Pass.
Areas included in the advisory span Northwest Beaverhead County, Beaverhead and western Madison valleys below 6,000 feet, and the Ruby Mountains and southern Beaverhead Mountains.
Communities affected include Dillon, Wisdom, Wise River, Glen, Dewey, Waterloo, Bannack, and Monida Pass, along with surrounding rural areas and mountain corridors.

Officials recommend drivers slow down and use caution while traveling, especially on elevated routes where snow may accumulate faster.
