In sintesi

An inversion will leave by Tuesday morning. Light snow, seasonal temperatures, with strong NW alpine winds are forecast. Forecasters still have low confidence in the snowpack at higher elevations, especially in thinner areas East of the divide. SH

Problemi valanghivi

    Deeper snowpack areas, mainly West of the divide, have quite a strong midpack, which was evident in field tests on Monday near treeline in the Little Yoho region. Thinner surface wind slabs, mainly on steep alpine slopes will be a concern.

  • Deep Persistent Slabs

    These slabs can be triggered from thin snowpack areas and propagate large distances to deeper areas. An example of this was a skier remote size 3 in the Lake Louise area on Sunday. The slab failed 140cm deep on weak basal facets and depth hoar.
