In sintesi

Wind pressed snow is widespread in the forecast region at the moment, Caution as new snow will bury and cover widespread wind slabs, making them hard to assess.

    Ice climbers be cautious in areas where loading has stressed the snowpack. Top outs and ledges may be particularity sensitive due to recent snow and transport winds.

    2 Large avalanches observed today on this layer from past 24 hours. Initiating this layer is more likely from large loads such as cornice fall or from shallow snowpack areas.

Snowpack Summary

Storm snow is bonding well to older snow surfaces. The Icefields has a well bridged mid pack overlying basal facets and depth hoar. The northern region is weak and shallow; bridging over the basal weakness is less reliable BTL.

Avalanche Summary

A field team down south noted two Deep persistent 3.5 size avalanches on SW & NE aspects in the alpine. Numerous loose dry observed on E-S faces from steep rocky terrain in the Icefields  A size 2 cornice release was also observed entraining storm snow from a steep lee feature in the Maligne
