Primary Problem: Loose Wet
Bottom Line: Temperatures will be 10 degrees warmer than yesterday and fewer clouds in the sky, accelerating snow surface warming. Wet snow avalanches will pack a serious punch, increasing in volume and traveling farther than yesterday. Southeast through west-facing slopes, and areas with exposed rocks or cliff bands, will be particularly susceptible. Limit your exposure to problematic aspects and slopes as the snow transitions from frozen and mostly stable to wet and unstable. Wind slab avalanches near high elevation ridgelines, and slides breaking on buried weak layers, specifically in the mountains south of Big Sky, and near West Yellowstone are additional concerns.

The Last Word

Eastern Oregon University is conducting a survey to better understand avalanche safety preparedness among motorized backcountry users like you. Your feedback will help us learn more about who is purchasing and practicing with avalanche rescue gear (beacon, probe, shovel) and participating in avalanche education, and why some riders aren’t.  The survey is confidential and anonymous. 

Your feedback is invaluable in improving avalanche education and awareness. Please take a moment to share your experience and help us make a difference.
