Points saillants

SE slopes and features that have been loaded by recent winds have developed dangerous slab conditions.

Problèmes avalancheux

  • Wind Slabs

    • Alpin

    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    1–3
    Variable strength windslabs continue to develop from moderate NW winds. These slabs have not yet proven to be reactive. Continued loading and/or rapid temperature changes or exposure to the sun will wake this layer up.

  • Storm Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière

    Taille
    1–3
    The storm dropped up to 60 cm of snow since Tuesday. The snow is now settling into slabs that will become more touchy as wind and settlement occurs.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité

    Heavy loads (large explosives) were able to trigger this layer proving the hidden danger of this weakness. Full path avalanches are possible. Likely triggers will be from shallow areas.
