Continued warm and wet conditions at all elevations have set the stage for small human-triggered wet avalanches. Caution when travelling near or around terrain traps.

Avalanche Summary

There have been no reported avalanches in our region.

Please help out your backcountry community by submitting a MIN report if you head out to the backcountry.

Snowpack Summary

The snowpack has rapidly diminished over the past 3 days due to warm temperatures and rain. Uncompacted areas are transitioning to isothermal conditions to the ground, and the crusts within the snowpack are deteriorating. Snow depth varies significantly based on the aspect, ranging from 50-100 cm and continue decreasing rapidly below the 1000-meter elevation mark.

The snowpack has yet to cover many early-season hazards and large areas of terrain are below avalanche threshold. Only specific terrain features with smooth ground cover, gullies, or established avalanche paths are above the threshold for avalanches.

Weather Summary

Terrain and Travel Advice

  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

Problems
