    Recently formed wind slabs may remain reactive to human triggers for several days after the winds die down. Wind slabs may be present on many aspects and elevations due to very strong and highly variable wind directions.

Confidence

Moderate - Due to the number of field observations

Weather Forecast

Avalanche Summary

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, expect wind slabs to exist on a wide variety of exposed slopes. A layer of surface hoar was reported around Hudson Bay Mountain last week, which now sits beneath 40-50 cm of settling snow. A thick rain crust that formed in early November is now buried 50-60 cm deep, and recent snowpack tests produced sudden results on facets (sugary snow) above this crust. 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.
