Be cautious near areas of wind loading and below convexities. The new snow needs time to stabilize.
In alpine and treeline terrain, snow has preferentially deposited on north and east aspects due to extreme southwest winds. Slab thickness could range from 15 to 60 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).
By Sunday evening, we could receive between 15 and 30 cm of new snow. This snow will fall on a variety of surfaces: wind-affected snow, powder, and sun crust.
A widespread melt-freeze crust about 2 cm thick is present at depths of 40 to 90 cm. A weak layer of faceted grains has developed on this crust on north to east aspects and is reactive in tests at treeline and in alpine terrain.
At mid-elevation, the average snowpack depth is around 140 cm.
