Lo esencial

New storm slabs are building in Alpine and treeline areas due to the new snow and strong SW winds.  The new snow helped but we need another 20-30cm of snow to see a significant improvement in the ski quality.

Problemas de aludes

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    In alpine areas the 1106cr isnt buried that deeply and we have experienced numerous settlements on this interface. No avalanches have been observed on this interface in some time.

  • Persistent Slabs

    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    Facets on top of the crust are continuing to produce moderate results indicating that there is still potential for human triggerring on this interface.

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–3
    New storn slabs are building in Alpine and treeline areas.  These are mainly on concern on N and E aspects due to the strong SW winds.

Confidence

Fair - Due to the number of field observations on Sunday

Weather Forecast

The storm wasnt as bit as we had hope and we can only expect to see about another 5cm over the next 24hrs.  Winds will begin to ease off and temperatures will slowly cool to more seasonal.  Cloudy conditions with isolated flurries are forecast for the next few days.

Avalanche Summary

No new avalanche activity was observed in the commonwealth ridge or Heros bowl area but visibility was limited throughout the day.

Snowpack Summary

The Storm was a bit of a let down with only 10-15cm of snow falling at higher elevations. Valley floors saw minimal new snow. The 0116SH is now buried down 10-15cm at treeline and below with the 1213CR down 40cm. A layer of facets overlying this crust continues to produce moderate sudden collapse results and we expect this problem to persist for some time. This areas continue to get weaker and facet out and most of the Alpine areas are wind affected. Some "good" skiing may be found in sheltered areas at treeline and below but you have to be creative to be able to find these areas.
