Lo esencial

The chance of human triggering will continue to decrease with a long period of cool weather and little precipitation forecast through next week. Facetting and slow weakening will be the next long term trend for the snowpack. JBW

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    2–3
    Hard wind slabs exist at treeline and above. These slabs can still be triggered on steep open slopes. It is likely that any slab will immediately step down to the weak base. Choose moderate slope angles & low consequence terrain.

  • Deep Persistent Slabs

    The weak base of depth hoar and facets is bridged by hard wind slabs and less likely to be triggered, however, skier triggered and natural full depth avalanches are still a possibility.
