Lo esencial

The alpine and exposed tree line has been hammered by SW winds. Expect slab conditions on any wind exposed slope. Sheltered glades will offer the best skiing.

Problemas de aludes

  • Wind Slabs

    • Alta montaña

    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    There is a veneer of wind slab on lee slopes ranging from soft slab on more sheltered slopes to hard slab on exposed slopes. Human triggering is possible which may then step down to the basal facet layer resulting in a large full path avalanche.

    Probabilidad
    Possible - Likely
    Tamaño
    2–3
    The weak basal facet layer is bridged by a supportive mid-pack below treeline and by hard slab on wind exposed features at treeline and above. This weakness is most likely triggered from thin areas in or on the edge of large open slopes.
