Avalanche Summary
No new natural avalanches were reported lately. There are limited reports and observations from this region. If you head into the backcountry this weekend, please submit a MIN report!
Snowpack Summary
Between 20 and 75 cm of recent snow sits on a melt-freeze crust. More significant amounts can be found in the western section of the region. Down 80 to 90 cm, there is a series of crust layers. The bond between these layers and the snow beneath them has been weak to moderate in strength. Near the ground, the snow lacks cohesion due to early-season cold temperatures and shallow snowpack. At 1750 m, the snowpack depth is around 110 to 165 cm.
Early season hazards such as rocks and stumps still lurk below the surface. Below treeline and even into treeline elevations are still below the threshold for avalanches.
Weather Summary
An arctic ridge of high pressure will become the main attraction for the next few days. Sunny and dry conditions will last up to Tuesday night.
Saturday Night
Clear sky. No precipitation. Moderate easterly ridge wind. Low of -12 C at treeline and -5C in the alpine due to a temperature inversion.
Sunday
Sunny with cloudy periods. No accumulation. Moderate northeast ride wind. High of -10 C at treeline and -3 C in the alpine due to a temperature inversion.
Monday
Increasing cloudiness. Flurries in the afternoon. Light northeast ridge wind increasing during the day. High of -6 C at treeline.
Tuesday
Cloudy. Isolated flurries. Moderate southwest ridge wind. High of -5 C at treeline.

Terrain and Travel Advice
- Seek out sheltered terrain where new snow hasn't been wind-affected.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Problems
Wind Slabs
Variable winds have created pockets of wind slabs on all aspects. While they are generally becoming less reactive, human triggers are still possible. Still not many observations, therefore uncertainty is high for this problem.
Aspects: All aspects.
Elevations: Alpine, Treeline.
