In sintesi

Decent skiing can be found on protected south and west aspects if you are capable of dodging wild alpine sharks (thinly covered rocks)

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2

    Thin wind slabs from the previous outflow winds. The problem mostly exists in the alpine with the exception of a isolated exposed treeline features.

  • Loose Dry

    • Alta quota

Weather Forecast

High pressure system with cool temperatures and clear skies will remain in place until Sunday evening where winds start to pick up to the moderate/strong range and the clouds roll in. A storm is supposed to push in next week. For more details: Avalanche Canada's, Mountain Weather Forecast.

Snowpack Summary

Thin windslabs and wind effect in the alpine and exposed treeline from recent outflow winds. Up to 20cm of soft snow in sheltered S and W aspects. This sits on top of the Nov crust (up to 2300m) and is supportive to skis. Basal facets showed variable results in tests from sudden collapse to no results. Overall the snowpack is thin and variable.

Avalanche Summary

Several loose dry avalanches in the alpine from steep terrain on a variety of aspects to up to size 2 (mostly size 1-1.5). One old size 1.5 wind slab observed from the outflow wind event in a cross loaded alpine feature.

Confidence

Wind effect is extremely variable
