Avalanche Bulletin - 2026-01-20

Depending on the amount of snow received by Tuesday evening, new wind slabs of varying size will form on north to southeast aspects. Be cautious of the layering of different wind slabs that may still be reactive. The best conditions are found below treeline.

Areas concerned: Mont Albert, Mont Ernest-Laforce, mont Hog's Back, Champs-de-Mars, mont Lyall, mont Vallières-de-Saint-Réal, mont Blanche-Lamontagne et Mines-Madeleine

Issued on: 2026-01-19 @ 17:00, Valid until: 2026-01-20 @ 18:00

Travel advice :

Approach lee and cross-loaded slopes with caution.
Seek out sheltered terrain where new snow hasn't been affected by wind.

Avalanche problem #1 : Wind slab
What Elevation?	Which Slopes?	Chances of Avalanches?	Expected Size?

Over the coming days, new wind slabs are expected to form on north to southeast aspects. Their thickness will depend on the amount of snow received Monday night and Tuesday. Wind slabs are generally most reactive while they are forming. Older wind slabs still appear to be reactive to skier loading in some areas. They are found on east to southwest aspects, with thicknesses ranging from 10 to 40 cm. Avoid wind-loaded areas until the wind slabs have stabilized.

Avalanche Summary

Small avalanches in the Mines Madeleine area were reported to the Mountain Information Network (MIN).

Snowpack Summary

Strong winds have created high variability in the alpine and at treeline: conditions range from scoured areas to stacked wind slabs and wind-compacted snow.

In wind-sheltered areas, 30–40 cm of low-density snow remains at the surface. Below 600 m elevation, a friable melt-freeze crust formed last Thursday is present at a depth of approximately 5–10 cm.

The December 20 crust is now buried at a depth of about 60–110 cm. The faceted grains at its surface are rounding and showing decreasing reactivity in stability tests. This layer appears to be gradually gaining strength.

The average snowpack depth at mid-elevations is approximately 120 cm.
