Recent snow and wind have created dangerous avalanche conditions. Stick to smaller, low-angle slopes.
Buried weak layers are most concerning at treeline elevations. Small slab avalanches may step down to this layer resulting in large, destructive avalanches.
Fresh snow from Tuesday has left slabs that will likely be reactive in steep terrain, especially on wind-loaded slopes.
Reports of avalanche activity have been limited. A notable size 2 persistent slab avalanche was observed in Manning Park (photo below). It likely occurred naturally over the weekend. A few small (size 1) storm and wind slab avalanches were observed over the weekend.
Tuesday's storm brought 15 to 30 cm of snow, likely forming fresh slabs at upper elevations and wind-loaded terrain. This snow sits above a thin crust on south aspects and settling powder on north aspects.
There has been evidence of two persistent weak layers roughly 80 to 120 cm deep. The upper one is a thin layer of facets and crusts or surface hoar while the deeper one is facets above a thick crust. While we have not seen many reports of persistent slab avalanches in this region, these layers should not be trusted based on notable activity in neighbouring regions.
