Good skiing to be found in sheltered areas TL and below!

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–3
    Stiff wind slabs observed in open areas at TL and above. These are sitting on a weak facetted bond will slide with skiers weight. Consider the consequences and chose your adventure carefully.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2
    This weak layer exists below a variable mid-pack at treeline and sub-alpine elevations. Large loads such as a cornice collapse or surface slides could still possibly trigger this deep persistent weakness.

Weather Forecast

Sighhhhhhh! No new snow expected for the foreseeable future. A very stable weather system is upon us for Monday. Broken skies, cold temps. Get out there and enjoy the great skiing in the sheltered areas.

Snowpack Summary

The Dec 20 facet/surface hoar layer that was proving very sensitive appears to be bonding exceptionally well to the crust below. Field team was in the Churchill slide paths and found the interface down 25cm and did not get any results to tests or ski cuts on steep terrain at TL and below. We found significant wind slab in open areas TL and above.

Avalanche Summary

No new avalanches reported or observed. Some collapses within the snow pack felt while touring up through the trees with no observable cracking.

Confidence

Wind effect is extremely variable
