Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2.5

    Snow and moderate winds forming new slabs on leeward and cross-loaded terrain features. These slabs will probably not bond well to the current snow surface.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1.5–3

    Be cautious of thick to thin snowpack areas being likely trigger locations.
