In sintesi

Parks Canada will be conducting avalanche control on Mt's Bosworth, Stephen, and Dennis tomorrow, Jan 27. No skiing or climbing in these areas.Field observations today saw strong W/SW winds redistributing snow in the alpine and at treeline.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2
    At treeline 30-50 cm of settled storm snow sits overtop of the Jan 20 facet interface. Where the wind has created soft slabs this layer is touchy and reactive to skier triggering. Immediate lees of ridges above treeline are the areas of most concern.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible

    In most parts of the forecast area a settled midpack overlies a weak facetted base. Be aware of steep shallow snowpack areas where the likelihood of triggering these basal facets is highest. The basal facets are still reactive east of the Divide.
