Problèmes avalancheux

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Very Likely
    Taille
    2–4
    Open slopes on Northeast to South aspects have slabs that are sitting on surface hoar 20-60cm down. On southerly aspects, the surface hoar formed on a sun crust, increasing the possibility of remote triggering and wide propagations.

  • Storm Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Certain
    Taille
    2–4
    Heavy snow and moderate to strong SW winds is expected to continue through the evening. A widespread wind/storm slab condition is producing large natural avalanches, especially in the alpine. Avoid all avalanche terrain.
