    Thursday's 10 cm and Sunday's 8cm of snow with little wind has covered the widespread wind slab condition that remains following last week's wind event. Current winds remain light and little change is expected in the snowpack.

    The once strong snowpack is starting to show signs of losing strength as faceting conditions dominate the weather picture.  Triggering avalanches is most likely to happen in thin snowpack areas. 

Weather Forecast

Cold temperatures and little or no precipitation is expected for the next several days.

Snowpack Summary

Thursday's 10 cm and another 8cm on Saturday has buried previous wind slabs at tree line and above. The mid-pack remains supportive however expect it to be loosing strength in shallow locations as the facetting process continues.

Avalanche Summary

Friday's avalanche control work at the Icefields released several loose avalanches up to size 2, from very steep terrain with thin snow cover at treeline. The few natural avalanches that have been observed share the same characteristics.
