Regions

Chic-Choc Mountains.

After a day without wind on tuesday (or almost ...), there is still snow available for transport in the mountains. Beware of the new wind slabs, they are more sensitive during their formation.

Snowpack Summary

The light density snow that fell over the last few days will be carried by northwest winds to settle on the leeward aspects. It will be added to the 20 to 50 cm of slightly denser snow on the January 18 crust. This snow, which is very pleasant to ski, is found in areas protected from the wind, particularly below the treeline and on the edges of trees at the treeline.A great deal of spatial variability is found in the alpine and treeline, from soft surface slabs, to wind-affected snow, to crust or rock.Facetted grains are developing on the January 18 crust, but no avalanche activity has yet been observed in connection with this interface. Below the January 18 crust is 15-20 cm of snow, generally well packed, overlying facetted grains from the decomposition of the January 2 melt-freeze crust. This interface rests on a mixture of laminated crusts and facetted grains at the base of the snowpack.In general, the height of the snowpack varies from 60 to 80 cm in the valley to 100 to 140 cm in the mid-mountain.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Wind slabs may be poorly bonded to the underlying crust.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
