The storm have left less snow than expected, which has been moved by northeasterly winds to form wind slabs in the upper lee slopes and cross loaded areas.

Watch out for wind-loaded areas, especially on steep slopes and convex rolls.

Snowpack Summary

Following the storm, an additional 10 to 15 cm of snow is added to the 20 to 30 cm of low density snow covering the January 2 crust. This crust supports the weight of a skier or snowboarder.

In areas exposed to the winds, there is a variety of surfaces affected by the wind, ranging from soft slabs to hard slabs, as well as sastrugis or the crust directly on the surface.

In general, the height of the snowpack varies from 50 to 100 cm depending on the area and the elevation.

Problems

Wind Slabs

An icon showing Wind Slabs

Wind slabs have developed with moderate to strong northeast winds over the past 24 hours. They are found at the top of W-SW-S slopes in the alpine and in cross loaded areas at treeline. Our observations of the day show that they react to the passage of a skier, but with a limited propagation.

Aspects: South, South West, West.

Elevations: Alpine, Treeline.
