Regions: Banff Yoho Kootenay.

Winter has arrived with up to 30cm of new snow in alpine areas. At treeline and below snow depths are still below threshold.

Weather Forecast

An additional 15-20cm is forecast overnight for alpine areas.  Clearing by midday on Sunday and cool and clear for the next few days.

Snowpack Summary

Up to 80cm of snow is present at higher elevations and the facetting process is well under way at the base of the snowpack. In places a thin wind slab exists over the facets. Expect sluffing in any steep terrain.

Avalanche Summary

Neighboring Kananaskis Country had a avalanche incident involving ice climbers today.  See the Kananaskis Public Safety Facebook site for more details.  Expect similar conditions in the Banff forecast region.

Avalanche Problems

Loose Dry

We expect the sluffing to taper off in the next couple days. Continue to watch for wind loaded pockets of snow.
Avoid travelling under cliffs that are exposed to sluffing from above.Be careful with wind loaded pockets while approaching and climbing ice routes.

Aspects: All aspects.
