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 2 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.
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.

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.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Problems
Loose Wet
Rain and warm temperatures may create the conditions for human and natural triggered avalanches.
Exercise caution near terrain traps; a small avalanche could pose risks, pushing riders into features like cliffs or gullies.
