Unusually dangerous avalanche conditions exist. Another storm Saturday through Sunday may produce 30+ cm of snow with strong Westerly winds, further deteriorating conditions. Backcountry travel in avalanche terrain is not advised this weekend. SH

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Very Likely
    Dimensione
    2–3
    As new snow accumulates this weekend, expect rapid wind slab formation, which will continue to overload the basal facets, increasing natural activity and the potential for human triggered avalanches.

  • Deep Persistent Slabs

    • Alta quota

    Up to 45cm of snow deposited last Wed. formed wind slabs 60-100cm deep. This has overloaded the weak basal depth hoar and facets. Lake Louise and Sunshine ski areas reported widespread activity up to 2.5 today from explosive control, some 200m wide.
