Stanley, Idaho – Life-threatening avalanche conditions are unfolding across central Idaho’s mountain ranges Friday as heavy snowfall and strong winds rapidly destabilize an already weak snowpack, making backcountry travel extremely dangerous through the night.
According to the Forest Service Sawtooth Avalanche Center in Ketchum, a Backcountry Avalanche Warning is in effect from Friday morning through early Saturday for the Sawtooths, White Clouds, Smokys, Boulders, and Pioneers. Avalanche danger is rated HIGH, meaning both natural and human-triggered avalanches are very likely. Large slides capable of burying people, snapping trees, or destroying structures are possible.
The most dangerous areas include terrain near Stanley, Smiley Creek, Galena Summit, and Trail Creek Summit, where wind-driven snow is heavily loading steep slopes. Officials warn avalanches may be triggered remotely, even from flat terrain above or below steep faces. Valley bottoms are also at risk, as long-running avalanches could reach roadways, trails, and isolated buildings.
Outdoor recreation in avalanche terrain is strongly discouraged. Travelers are urged to stay completely off slopes steeper than 30 degrees and avoid runout zones beneath them. Even experienced backcountry users face severe risk under current conditions.
Dangerous avalanche conditions are expected to persist through the night as snowfall and winds continue. Additional avalanche warnings or extended advisories may be issued as conditions evolve. Officials urge anyone heading outdoors to consult the Sawtooth Avalanche Center for the latest updates before traveling.
