Regions: Waterton Lakes.

Cornices are large and are generally sitting over the areas the best skiing can be found. The windslabs are building as I am writing this.

Weather Forecast

Friday mainly sunny with an alpine high of -2 and moderate to strong westerly winds.

Avalanche Canada's Mountain Weather Forecast is a great regional-scale resource for up-to-date weather information. SPOTWX is a good resource for local scale weather forecasts.

Snowpack Summary

Up to 15cm of new snow sits on a thick crust that exists to ridgetop except on high north faces. This tops a well consolidated snowpack with the lower half composed of dense facets and decomposing crusts, none of which have been reactive in snowpack tests or recent avalanches. Large cornices observed overhead where good skiing can be found.

Avalanche Summary

No avalanches reported or observed.

Please consider submitting a MIN report if you see an avalanches.

Confidence

Freezing levels are uncertain
