Evaluate November Crust carefully prior to committing to bigger slopes.

Weather Forecast

Cold temperatures and light winds persist through to the weekend. Day time high temperatures in the alpine will be around minus 20.

Snowpack Summary

There is 30-70 cm of settled snow overtop of the November 12 crust. Stability tests on this crust are mixed, ranging from no results to easy results. Recent avalanche activity suggest this crust is more reactive in the Lake Louise area on southerly aspects at tree-line and above elevations. Small wind slabs only found in isolated areas in alpine.

Avalanche Summary

Of note is a skier triggered avalanche in the Lake Louise side-country on Tuesday. This was on a southerly aspect and ran on the November crust. Lake Louise Ski Hill also reported on Tuesday an explosive triggered avalanches up to size 2.5. This was also on a south aspect and running on the Nov crust.

Avalanche Problems

Deep Persistent Slabs

Dominant issue in the snowpack is the November 12 crust (down 30-70 cm). This crust is evident throughout the region and has started to become reactive on south aspects in the Lake Louise area.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3
