Lo esencial

Another warm, wet system is pushing into the Rockies and we may receive up to 20cm in the alpine overnight, accompanied by strong west winds. This will likely result in a natural avalanche cycle in the alpine and open tree-line features on Thursday.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–3
    Wind slabs up to 1m deep can be triggered by a person in avalanche terrain. Pay attention to the hardness of the slab; the greater the hardness, the greater the propagation potential. This means large avalanches are possible if you trigger something.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–3
    The basal facets/depth hoar are becoming less reactive in field tests, but If a wind slab is initiated, it may have enough volume to step down to create larger avalanches. Other trigger points will be thin, cross-loaded features and ridge crests.
