Points saillants

Recent winds and new snow have loaded lee features in the alpine.  Good skiing can be found throughout but should be approached with caution for wind slabs.

Problèmes avalancheux

    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    1–3
    Wind slabs continue to grow and likely becoming stiffer in the alpine and lee features at treeline. These are sitting on a weak layer of storm snow that has yet to settle.

  • Persistent Slabs

    Widespread, yet variable in terms of how strong it is. In most areas it is still strong and supportive, but in isolated areas, it is relatively weak.

Avalanche Summary

No new avalanches were observed. 

Snowpack Summary

8cm of new snow overnight brings our storm snow to about 25-30cm at treeline and up to 40cm in the alpine. The winds have been transporting snow in the alpine all day, so expect wind slab development around ridges and lee features.  It is possible that this wind effected snow extends to tree line as yesterday had winds from all directions.
