Lingering wind slabs are likely becoming more challenging to trigger, but they may still be found in steep unsupported terrain at treeline and above.
After many windy and cold days, the best riding is likely in terrain sheltered from the wind.

No recent avalanches have been reported, but observations are limited this time of year. If you do head into the backcountry please submit a MIN report!
Strong wind from the east over the past week has scoured east slopes and created hard wind slabs on south and west facing slopes.
A layer from mid-November is buried 50 to 70 cm deep at treeline. This layer consists of surface hoar, facets and as a crust below treeline and on south facing slopes. This layer was reactive a week ago (Nov 27 and 28), but has likely trended towards being unreactive under the current conditions.
Many early-season hazards exist below treeline such as rocks, stumps, and open creeks.
