In sintesi

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–3
    Cornices are large and can collapse anytime. This is a trigger that could initiate a full depth avalanche. Pay attention to what is above and avoid cornice exposed slopes.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    2–3
    Time to put full depth avalanches on the radar. The potential for this is related to extent of overnight recovery, large triggers such as a cornice failure, and daytime warming. This increases as spring conditions progress.

Weather Forecast

Cooler temperatures with a few snow flurries over the weekend before warmer weather pushes back in next week.

Snowpack Summary

Warm temps have softened up the snow surface into spring conditions. At treeline, lee aspects have a series of windslabs sandwiched with thin weaknesses in the upper snowpack. A strong midpack bridges over weak basal facets on Northerly aspects at treeline and above.

Avalanche Summary

No new avalanches observed or reported today. One size 3 slab with a 2m crown was observed on Indian Ridge on Tuesday. Time to put full depth avalanches on the radar.
