Summary
Weather Forecast
Continuous light snowfalls will occur through the weekend with a potential of up to 30cms in the Icefields area by Sunday night. Ridgetop winds will increase to moderate from the Southwest by Saturday afternoon, redistributing some of the new snow onto lee aspects. Temperatures will remain relatively mild between - 2 to -10 C.
Snowpack Summary
A couple cms of new snow fell today with minimal wind effect. Wind slabs created after last week's storm continue to be our biggest concern in the snowpack, particularly at ridge tops and cross loaded features.�
Avalanche Summary
No new avalanches were observed in the past 48 hours.
Confidence
Intensity of incoming weather systems is uncertain
Problems
Wind Slabs
No new natural activity on this layer has been noted for a few days yet potential still exists on steep unsupported wind loaded slopes.
Avoid lee and cross-loaded terrain near ridge crests.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Expected Size
Persistent Slabs
A persistent facetted weakness can be found around a mid-pack crust. There is low likelihood of natural avalanches occurring on this layer but we are watching as each small system deposits more snow load.
Aspects: All aspects.
Elevations: Alpine, Treeline.
