Avalanche Canada
Wind slabs, formed by northerly winds, can be found on lee features in the alpine and may not bond well to a recently formed crust. Use caution as you transition into wind-affected areas.

Confidence
Moderate
Avalanche Summary
No new avalanches were reported.
Isolated wind slabs may be possible to human-trigger. The most likely terrain is directly lee of high spots and ridge features.
Snowpack Summary
10 to 15 cm of new snow has accumulated and may become moist with rising freezing levels and periods of sun. This new snow sits over a surface crust on all aspects and elevations.
A persistent weak layer of facets sits on top of a second buried crust down 80 to 180 cm. This layer is unlikely to be human-triggered in areas where a thick crust above the weak layer is present.
