    Hard touchy windslab in the alpine and open tree-line features showing very serious potential for wide propagation in connected features.

    Avalanches initiated within the storm snow may step down to deeper layers and in some cases gouging to ground in thin snowpack areas.

Weather Forecast

Cooling along the Icefields parkway as approaching system enters the forecast region. SW-ly winds expected to increase to moderate values for Tuesday night and into Wednesday with the arrival of the warm moist air. Light precip in the form of rain and moist snow expected for all elevations.

Snowpack Summary

Hard surface windslab in the alpine and open tree-line features. Recent HST in sheltered locations at tree-line and below forming a cohesive soft slab over a faceted mid-pack with only marginal support below tree-line. This is all sitting on a weak base of large facets and depth hoar to create an overall delicate and untrustworthy snowpack.
