Lo esencial

Watch for the wind to switch directions to the north and for temperatures to drop on Friday afternoon that will mark the end of the snowfall.

    Forecasted snow and moderate winds will likely develop a reactive windslab through the weekend. Watch for the winds to switch directions to the north and the temperature to drop.

    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 with new load.

Snowpack Summary

The Oct. 25th crust/facet combo remains the main concern. This layer is buried an average of 30 to 65cm, and is present on most slopes with sufficient snowpack for safe skiing - we expect this layer to linger for sometime. Forecasted snow and moderate 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.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Friday
