Points saillants

Remember that this cold weather makes even a minor injury potentially serious. If you're brave enough to adventure in this weather then keep your days short and conservative.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2

    Reverse loading from NE winds are creating wind slab on non-typical SW aspects in the alpine.

  • Loose Dry

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Likely
    Taille
    1–2

    The cold temperatures and the clear skies will trigger loose dry avalanches from steep rocky terrain. These avalanches by themselves will be of low risk unless you are in a terrain trap or above a cliff.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1.5–2.5

    You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.
