Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità

    Dimensione
    1–3
    Up to 30 cm recent storm snow coupled with strong westerly winds have created soft and hard slabs in the alpine. These slabs are reactive to skier triggering and may step down to the deeper surface hoar layer resulting in a very large avalanche.

  • Persistent Slabs

    The Valentine surface hoar is now down 70-120 cm. Natural activity with this layer is subsiding, however, it is still prime for human triggering. This layer is producing moderate shears in test pits.
