Kernpunkte

Incoming snow will improve the ski quality at higher elevations. Keep in mined that early season hazards still lurk below the shallow snowpack.

    Best to assume all skiable slopes have this layer, and assess the strength of this interface before committing to a line. With forecasted snow values adding more load to the snowpack expect this weak layer to become more reactive through the storm.

Snowpack Summary

The Oct. 25th crust/facet combo remains the main concern. This layer is buried an average of 20 to 50cm, and is present on most slopes with sufficient snowpack for safe skiing - we expect this layer to linger for sometime. Forecasted snow and strong winds will add more load to this weak layer as well as create new windslabs  at higher elevations.

Avalanche Summary

Last week the Oct 25th layer produced some large natural avalanches (up to size 2.5) throughout the Rockies from as far south as Kananaskis Country, north to Yoho, the Icefields, Jasper and Marmot Basin Ski Hill.
