Lo esencial

Sheltered areas will have some decent skiing but thats about it.  We still have low confidence in our current snowpack and we are playing it conservative out there.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–2.5
    Be aware of cracking around your skis as you approach tree line. This is a good indicator of wind slabs.
  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    2–3
    Any avalanche has the potential to trigger the basal facets, resulting in large avalanches.

Weather Forecast

Winds are forecast to calm down but unfortunately the damage is done...  Temps will remain above average around -4C and no new snow is in the forecast till maybe after the weekend....  The ice climbing is great right now though!!!

Snowpack Summary

Wind and basal facets are the themes this year so far... Another windy day again today has added to the wind slabs in the alpine and open areas at tree line. Northerly and Easterly aspects and lee feature are most likely to have more snow and soft slabs because of the winds.  This is a reminder that the bottom half of the snowpack is weak and consists mostly of facets. Good skiing can be found on moderate angles and the forecasters are staying off of the steeper lines and away from large slopes. Any avalanche that occurs has the potential to step down to the basal facets creating an even larger avalanche.  Skiing is OK but not great.  Still feels like a low snowpack year...
