In sintesi

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.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    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.
  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    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.
