In sintesi

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.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Very Likely
    Dimensione
    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 quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Very Likely
    Dimensione
    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
