No significant new avalanche activity has been reported.

Up to 10cm of new snow overlies the previous variable snow surface from late last week, which includes hard wind pressed or scoured areas, old wind slabs, weak faceted snow, or small surface hoar. The cold temperatures appear to be preserving the old (now buried) wind slabs from the end of last week and they still may be reactive to human triggering in isolated areas. Recent snowpack tests near Whistler gave hard but sudden results in faceted snow under the old hard wind slab. Moderate southwest winds over the weekend and more recent northerly winds have formed soft wind slabs in immediate leeward features. The widespread mid-November crust is typically down 1-2m in the snowpack. Recent snowpack and explosive tests have shown the crust to be unreactive, but it could remain a problem in shallow alpine start zones.
