Regions: Kananaskis.

Strong SW winds have arrived with the Chinook flow. Sheltered areas will hold the best potential for early season turns but with the limited options out there right now, popular places have been heavily skied! Hope for a bit of a re-set to the skiing on Sunday! 

Confidence

Moderate -

Weather Forecast

Saturday will likely see warm temps and strong winds continue with no much in the way of new snow. More snow is forecast to begin overnight on Saturday and give us 10-15cm by Sunday afternoon

Avalanche Summary

No new avalanches were observed. 

Snowpack Summary

Strong winds today developed new windslabs in Alpine terrain and even down to treeline in some areas. These new windslabs can be found along ridgecrests and crossloaded gully features.  

Two main persistent concerns in the snowpack at this time. The October crust just off the ground down 50-60cm and the November Crust down 10-20cm. Both will be long term problems.

Avalanche Problems

Wind Slabs

These slabs formed with the recent Chinook pattern flow. Expect to encounter them on N and E aspects and gullied terrain or between pitches of ice climbs. 

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Persistent Slabs

No Activity on this layer yet but a windslab starting in the upper snowpack may step down to this layer. Any avalanche involvement would be a rough rocky painful ride right now. 

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
