Concern still exists for last weeks storm snow (20-30 cm) where it overlies a crust on solar aspects. Some recent avalanches have been observed on this interface.
Avalanche Summary
A skier accidental involvement was reported in the Lake Louise area yesterday. This points to ongoing problems with the upper portion of the snowpack.
Snowpack Summary
Variable surface conditions with dry snow present on polar aspects above 1600 m and temp crusts to ridgetops on solar aspects. Small wind slabs found in the high alpine. Concern still exists for last weeks storm snow where it sits on a buried suncrust (down 20-30 cm) on south and west aspects. Shallow snowpack areas are also still a concern.
Weather Forecast
Light flurries and a mixed bag of sun and cloud into Sunday. Large inputs of solar radiation should increase the possibility of lose avalanches in the afternoon.
