Lo esencial

Cool temps with light snow and winds will prevail until the arctic air reaches us on Wed PM. This will decrease natural avalanche activity, however the snowpack is still primed for human triggering, as seen with results from avalanche control today.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Very Likely
    Tamaño
    2–3
    Yesterdays warm, wet storm created new windslabs which sit on top of a weak snowpack. These windslabs are very susceptible to human triggering and will likely step down to the basal depth hoar.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Very Likely
    Tamaño
    2–4
    60-100cm of recent storm snow sits over weak basal depth hoar. Although, the natural cycle has passed, this layer is still reactive to light loads. An avalanche control mission today produced full depth avalanches to size 3 showing wide propagation
