In sintesi

Recent snowfall has increased the avalanche danger and will take time to stabilize - avoid avalanche terrain until the cooler temps arrive and strengthen the snowpack.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely - Very Likely
    Dimensione
    2–4
    Gusty and variable winds have formed wind slabs on all aspects at upper elevations, especially in exposed areas. These slabs will be more sensitive to triggering with the latest storm snow.

    15-20cm of new snow fell on Sunday along with moderate to strong SW winds. Steady rain fell below 1400m. Widespread storm slabs will be very touchy until the arrival of colder temps later in the week.
  • Deep Persistent Slabs

    Possible - Likely
    Dimensione

    Early season wind slabs that sit above weak basal facets have received significant load with the recent wet and heavy snow. This new load has the potential to cause full depth releases and wide propagations.
