Kananaskis Country Avalanche Forecast

Mar 23rd, 2019 3:00PM

The alpine rating is moderate, the treeline rating is moderate, and the below treeline rating is low. Known problems include Wind Slabs and Deep Persistent Slabs.

Cooling temps will help lock in the snowpack tomorrow. We are expecting a dusting of snow tonight. We'll see if its enough to get good dust on crust skiing.

Despite the cooling. this is still on our minds. By day 2 of the cooling we'll become more comfortable with this layer, but for now its still on the radar.
Be aware of thin areas that may propogate to deeper instabilites.Be aware of the potential for full depth avalanches due to deeply buried weak layers.Be aware of the potential for wide propagations due to the presence of hard windslabs.

Aspects:

All aspects.
