Avalanche Summary

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

The heat and rain expected on Wednesday and Thursday are likely to significantly transform conditions in the mountains. Although 20 to 35 cm of snow fell over the weekend of December 7 and 8, the majority of sectors in our forecast area remain below the critical threshold for triggering avalanches. However, the wind at higher altitudes has redistributed the snow, creating heavier accumulations in couloirs 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

Tuesday evening and night: Intermittent light snow. South wind, 30 to 50 km/h. Warming, maximum -4.

Wednesday: Snow changing to rain. Wind southeast, 50 to 70 km/h. Maximum +1. Freezing level rising to 2600 m.

Thursday: Rain, 20 to 40 mm in total. Wind southwest, 60 to 80 km/h. High +9. Freezing level 2800 m.

Friday: Alternating sun and clouds. Wind west, 30 to 50 km/h. Maximum -7.
