Snowpack Summary

Around 25 cm of powdery snow lies on the surface in non-skied areas except on slopes exposed to west winds. Lower down, harder layers cover flat-faced crystals just above the January 18 icy crust. This brittle interface can be unstable, especially in the upper part of the couloirs with ice cascades.

Snow depths range from 70 to 120 cm in general.

Weather Summary

Friday evening and night: Blowing snow. 5 cm of snow. Wind northeast 20 to 35 km/h. Low -9 C.

Saturday: Cloudy. 2 cm of snow in the morning. Clearing in the afternoon. Wind northwest 25 to 35 km/h. High -11 C.

Sunday: A few flurries (1 cm). Wind west 40 to 70 km/h. High -5 C.

Avalanche Problems

Persistent Slabs

This problem appears to be active only at the base of icefalls present above forest corridors.

Aspects: North, North East, East, South East.

Elevations: Below Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5

Wind Slabs

Loading by the storm in progress

Aspects: North, North West.

Elevations: Below Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
