Confidence

Moderate - Due to the number of field observations

No recent avalanches have been reported in this region.

Snowpack Summary

Clear skies and strong outflow winds have created a variety of snow surfaces including scouring and hard wind slabs in exposed areas and surface hoar formation in sheltered areas. Recent winds have blown from many directions, most recently from the east. As a result, wind slabs may exist on a wide variety aspects. According to reports near Smithers, there is a layer of surface hoar down 40-50 cm, though no recent activity has been reported on this layer. A thick rain crust that formed in early November is now buried 50-60 cm deep. Early season snowpack observations are still very limited in the region, but reports suggest the average snowpack depth is 50-90 cm at treeline and 120 cm or greater in the alpine.
