Hazard is improving, but forecasters still have concern for larger isolated avalanches. It is still a good idea to avoid big features and unsupported terrain.
Summary
Weather Forecast
Mixed sun and cloud with isolated flurries along the divide for Friday. Winds forecast to be moderate from the SW and freezing levels will remain around 1400 m. Some weather models predicting 10-20 cm of new snow by end of weekend.
Snowpack Summary
10-20 cm of dry snow over the past 48-hours sits over top of a well settled mid-pack. In the deeper snowpack areas the lower snow-pack is well settled and displays no significant shears. In shallower areas the lower snow-pack is consists of weaker facets. Isolated wind slabs exist near ridge tops and in lee terrain at alpine elevations.
Avalanche Summary
No natural activity observed. The ski-hills reported small wind-slabs in the alpine that were reactive to ski-cutting. Lake Louise ski hill reported an-out-of-bounds skier triggering a size one wind slab in the Lipallian area.
Confidence
Problems
Wind Slabs
Small wind-slabs can be expected near ridge-tops and lee terrain in the alpine.
- Use caution in lee areas. Recent wind loading has created wind slabs.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.

Expected Size
Deep Persistent Slabs
The mid and lower snowpack is generally strong in this region. Concern still exists for shallower areas where basal facets may exist. Examples are wind affected terrain in the alpine.
Aspects: All aspects.
Elevations: Alpine.
