Regions: Kananaskis.

Strong winds in Alpine areas have created widespread wind slabs. Treeline has good skiing but the snow amount taper quickly with elevation. 

Confidence

Moderate -

Weather Forecast

Temperatures will remain seasonal on Friday with day time highs around -10. Winds will continue in the moderate range out of the SW and we should see another 5-10cm by days end on friday. 

Avalanche Summary

Numerous loose dry avalanches up to sz 1.5 on all aspects from steep alpine areas

Snowpack Summary

The recent storm snow has settled down to about 15cm of snow. Widespread wind affect is visible in the alpine but treeline was still providing good skiing today. The problem is that the snow tapers to only 40 cm at lower elevations below treeline which is pretty rugged. Watch for windslabs up to 25cm thick in alpine areas as well as isolated places at treeline such as gullies and convexities.   

Avalanche Problems

Wind Slabs

Widespread windslabs in alpine areas and more isolated in treeline. Many S and W aspects have been blown free of snow along ridgelines. 

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5
