Avalanche Forecast
Regions: Chic-Chocs.
Recent test results show that wind slabs are still sensitive to human triggering. Cold temperatures significantly slow snowpack stabilization.
Confidence
Moderate
Avalanche Summary
No new avalanches reported or observed
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
At treeline and in the alpine, surface snow is strongly affected by wind, resulting in great variability in its distribution.
In wind-protected areas, the average depth of snow cover varies between 90 and 120 cm. Within this blanket, we find:
A thin layer of frost at a depth of around 20 cm.
A layer of facetted grains approximately 40 cm deep.
A melt-freeze crust at 60 cm.

Terrain and Travel Advice
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
- Watch for areas of hard wind slab on alpine features.
Avalanche Problems
Wind Slabs
With moderate winds and snow available for transport, wind slabs continue to form. Cold temperatures are slowing down the stabilization of the snowpack. These wind slabs, which are sometimes hard, are more difficult to trigger, but they encourage propagation in the event of breakage. They rest on fragile layers that proved reactive in our tests.
Aspects: North, North East, East, South East, South.
