In sintesi

Cold for the next few days.  Slower skiing due to the cold temperatures. 

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2
    Wind slabs are present in the Alpine on all aspects, and in isolated spots at Treeline. Steep and unsupported terrain are areas where triggering is more likely.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely
    Dimensione
    2–3
    Triggering of a deeper slab is unlikely, but still possible in shallow snowpack areas.

Weather Forecast

Cold weather until at least Friday with overnight lows in the minus mid-twenties and daytime highs around -20c.  Isolated flurries for Wednesday with west wind at 20-40km/hr.

Avalanche Summary

No new avalanches observed or reported.

Snowpack Summary

Not much changing in the snowpack at the moment, except more profound faceting due to the persistent cold temperatures. Wind slabs are found in the Alpine on all aspects and in open areas at Treeline immediately below ridge-crests in lee and cross-loaded terrain. The Dec 15th surface hoar layer is found down 20 to 30cm at elevations below 2200m, but the lack of an overlying slab means that this layer of concern is not yet active. The November crusts are beginning to facet and as they continue to become weaker, this layer will become problematic.
