Regions: Kananaskis.

Not a lot of change out there right now. We will be watching the deeper layers and seeing how they evolve over the days/weeks to come. But for now, windslabs are the principle concern.

Weather Forecast

Back to a more typical November...

Tomorrow will have strong treeline winds from the west, steady temperatures hovering around -10 and maybe...just maybe some light flurries. Here's hoping. 

Avalanche Summary

Nothing noted or reported today. 

Snowpack Summary

There is an obvious crust down 20-30cm in the trees below 2100m. The surface snow is starting to facet out which makes for pretty good travel. Above the 2200m the crust gradually turns into windslabs of varying hardness. It appears the north winds have loaded southern slopes near ridges. 

Terrain and Travel

  • Pay attention to isolated alpine features as well as cross-loaded features at treeline.

Avalanche Problems

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