The National Weather Service has issued a Winter Weather Advisory for several mountain ranges across Gallatin and Madison counties in southwest Montana, including the Ruby Mountains, Southern Beaverhead Mountains, Centennial Mountains, and the Gallatin and Madison ranges. The advisory is in effect from 11:00 P.M. Monday until 5:00 P.M. MST Tuesday, with forecasters calling for 2 to 6 inches of snow at lower elevations and up to 10 inches possible in the mountains.

Why it matters

The winter weather system could create difficult driving conditions, especially at higher elevations and open stretches where blowing snow reduces visibility. Several high-travel corridors and mountain communities are included in the advisory area, including Targhee Pass, West Yellowstone, Monida Pass, Big Sky, Raynolds Pass, and Bozeman Pass.

The details

While the snow totals may not sound extreme by Montana standards, the timing and wind could make this system more impactful. Officials warn that travel could be very difficult at times, particularly at higher elevations and open stretches where blowing snow reduces visibility. Even lighter accumulations can create slick roads when paired with gusty winds and dropping temperatures.

• The advisory goes into effect at 11:00 P.M. Monday and remains in place until 5:00 P.M. MST Tuesday.
• Forecasters are calling for 2 to 6 inches of snow at lower elevations across much of the area, and up to 10 inches possible in the mountains.
