Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    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

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    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

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–4
    Large loads (cornice fall) recently triggered full depth avalanches on this layer on wind-loaded slopes in the alpine.
