This is a brief return of winter at higher elevations, with up to 15 cm of new snow expected and moderate winds promoting the formation of wind slabs. Uncertainty remains regarding how the moist snowpack will react to this new snow. Pay attention to areas of wind loading during your travel.
New wind slabs are expected to form in the upper parts of slopes and below convexities. The bonding between these slabs and the old snow is uncertain. The estimated thickness of the wind slabs ranges from 10 to 40 cm.
No new avalanches have been observed or reported.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
New snow will accumulate overnight from Sunday to Monday on a moist snowpack. A crust may form at the interface between the two layers.
A widespread melt-freeze crust is present at a depth of about 10 to 50 cm, and the snowpack below this crust is well consolidated.
At mid-elevations, the average snowpack depth is around 125 cm.
