    Wind effect and windslab are common through the region with varied reactivity. Ridge tops and immediate lee features pose the most obvious hazard to triggering but anywhere with visible wind effect can pose a threat.

    New snow will need some time to settle and stabilize.

  • Deep Persistent Slabs

    1.5–3

    Skier triggering could occur in shallow snowpack areas or from large load. The consequences of triggering would be severe! Caution traveling, skiing and climbing in run out zones as avalanche have the potential to run full path

Snowpack Summary

Storm snow overlies a variety of surfaces depending on aspect and elevation. New wind slabs forming on lee aspects. The Columbia Icefields region has a well bridged mid pack overlying basal facets and depth hoar. The northern part of the forecast region has a generally shallower snow pack that is less bridged.

Weather Forecast

Snowfall tapering off through the day Wednesday as the front moves east and a shallow ridge builds. This will be quickly replaced by another front on Thursday; accompanied with rising freezing levels, snow and strong winds. Forecasted snow overnight, 15cm; to add to the previous 20-25cm fallen over the last week.

Avalanche Summary

Few small natural avalanches observed in steep cross-loaded features, at tree-line along the Colin Range in the Maligne Valley.
