👉 DECEMBER 10 BULLETIN👈
Most of our forecast area lacks sufficient snow cover to trigger avalanches. However, some of the few currently skiable couloirs, gullies and areas of maximum accumulation require extra vigilance and have enough snow to produce avalanches. Conditions remain typical of the early season: be careful!

Avalanche Summary
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
Despite an accumulation of 20-35 cm of snow over the weekend of December 7-8, most parts of our forecast area remain below the critical threshold for avalanche triggering. In the mountains, the wind has redistributed the snow considerably, forming larger accumulations in ravines and gullies.
The average height of the snowpack varies between 20 and 50 cm at the foot of the mountains. East of Route 299, local accumulations can exceed 70 cm.
The snowpack is typical of early-season conditions. Expect thin snow cover with rocks, trees and stumps buried just below the surface.
Weather Summary
Monday evening and night: Light snow. Wind northwest, becoming light east then southeast. Low -17.
Tuesday: Cloudy, light snow in afternoon, 2 to 4 cm. Wind southeast, 30 to 60 km/h. High -8.
Wednesday: Snow changing to rain. Wind southeast, 50 to 70 km/h. Maximum +3. Freezing level rising to 2600 m.
Thursday: Rain, 20 to 40 mm in total. Wind southwest, 60 to 80 km/h. High +12. Freezing level, 3700 m.
We invite you to consult the public weather resources recommended when preparing for a mountain outing and available here, as well as our alpine weather forecast.
Terrain and Travel Advice
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
Problems
Wind Slabs
The danger is mainly concentrated in ravines and gullies where snow has accumulated in sufficient quantities to trigger avalanches. The challenge lies in the fact that these types of terrain are among the few areas that are currently skiable. Increased vigilance is therefore recommended in these areas.
