    Probabilidad

    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

    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.
