No recent avalanches have been reported, but reports are limited.
Snowpack Summary
Snowpack depths are likely highly variable across the region, with elevation, and in wind-exposed areas. Low-elevation and wind-affected areas likely have a shallow faceted snowpack. While in higher elevation sheltered areas the recent storm snow is likely settling and gaining strength; however, weaknesses at the old snow interface down approximately 40cm may still need time to heal. In the Ashman Ridge area on Sunday, this interface gave easy compression test results. Northerly outflow winds are likely forming fresh wind slabs in exposed lee terrain and scouring windward terrain. Average snowpack depths near treeline are highly variable, but around a metre in sheltered areas.
