Montana avalanche danger rises with arrival of subtropical storm
A backcountry avalanche warning was issued for Northwest Montana on Monday as a freight train of Pacific moisture is set to deliver copious amounts of rain, ice and snow to the region.
The avalanche danger may rise to a “high” rating by Tuesday morning as the warm and wet storm sweeps across the forecast region, the National Weather Service in Missoula warned Monday. If the storm develops as forecasted, rain on snow will increase the likelihood and size of triggered and natural avalanches.
The avalanche danger area includes steep slopes above 5,000 feet in the Whitefish Range, Swan Range, Flathead Range and parts of Glacier National Park, including the John F. Stevens Canyon, the Apgar Range and Marias Pass areas.
Travel in avalanche terrain will become increasingly dangerous as the storm ramps up. Avalanches may run long distances and into areas with barren ground.
