Problèmes avalancheux

  • Wind Slabs

    Probabilité
    Possible
    Taille
    1–2
    Soft slabs 10-50cm overlay a buried surface hoar layer. A shift to winds from the NE may create slabs in areas that do not normally get high snow load. Saturday, a size 2 slab was observed on a convex roll at treeline on this layer.

  • Deep Persistent Slabs

    Increased loads with wind or new snow may awaken this instability. Gully features in the alpine and treeline which have been heavily loaded may step down to this layer.
