Lo esencial

Thin wind slabs may have formed in isolated areas at upper elevations. Avalanche activity is unlikely in most terrain due to a thick crust.

Avalanche Summary

No avalanches have been reported on the Island this week. If you are recreating in the backcountry please consider filling out a Mountain Information Network report. 

Snowpack Summary

Up to 5cm sits over a thick and supportive crust which caps the snowpack on all aspects and elevations. It may be possible to find thin wind slabs in the alpine and treeline in isolated areas.

Below the crust, 10-60 cm well settled snow and old crust layers sit above the thick late-January crust which extends to mountain top elevations on all aspects. The mid and lower snowpack is considered well settled and strong. 

Shallow snow cover at low elevations leaves many hazards like stumps and creeks exposed at or just below the snow surface.

Terrain and Travel

  • Wind slabs may be poorly bonded to the underlying crust.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
