In sintesi

Challenging travel below 2150m. Better skiing in the alpine.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1.5–2.5

    With forecasted NW winds, Reverse loading becomes a possibility. You may find windslabs where you normally would not.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    2.5–3.5

    Treeline: The Dec 1 crust exists up to 2150M. Currently this is showing no results in tests. This may become a concern later in the season.

    Alpine: We are starting to find Basal Facets in the snowpack.

Weather Forecast

Avalanche Summary

No new avalanches have been observed. There are several older impressive ones out there.

Snowpack Summary

The key here is 2150m. Below this elevation, there are several crusts within the snowpack that have tightened up and are very supportive but challenging to ski. Once you ascend past 2150m, the crusts disappear and there is a generally well consolidated snowpack that skis well. Definitely be on the lookout for some wind effect in the alpine. 

An avalanche triggered on the surface has the potential to affect the basal facets for an even larger slide. Take the time to dig a pit and evaluate the snowpack. 

Terrain and Travel

  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Approach lee and cross-loaded slopes with caution.
