Small avalanches in isolated areas or extreme terrain remain possible, even with a Low danger rating. If snowfall amounts on Wednesday are higher than forecast, consider a Moderate danger rating rather than Low in the alpine and at treeline.
In some areas on southeast through southwest-facing aspects, small pockets of wind slabs may still linger and could react to the passage of a skier. These wind slabs are estimated to be 5–30 cm thick.
A small natural size 1 avalanche was observed on a south-facing aspect of the Serpentine bowl. It likely occurred on Monday.
Another avalanche triggered by a user on Monday in the Grand Couloir on Hogs Back was reported to the Réseau d’information en montagne (MIN).
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
In the alpine and at treeline, the snowpack shows strong spatial variability: north and west-facing aspects are mostly scoured, while other aspects offer a mix of wind-affected snow, stacked older wind slabs, and about 10 cm of light surface snow in lee areas.
Below treeline, 10–15 cm of powder overlies a progressively denser snowpack down to the crust formed on December 20.
A new sun crust is present on steep south-facing aspects.
The average snowpack depth at mid-mountain is approximately 120 cm.
