Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2
    Moderate to strong Northerly winds are continuing to reverse load lee features and new slabs will bond poorly with cold temperatures. A small windslab could be sufficient trigger for a large basal facet collapse.

  • Cornices

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2
    Recent cornice failures caused several avalanches to size 3 on Saturday. Cold temperatures should make cornices temporarily less failure prone.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    2–4
    Large loads (cornice fall) recently triggered full depth avalanches on this layer on wind-loaded slopes in the alpine.
