Observations since the storm are limited, so monitor new snow depth and reactivity as you travel. New wind slabs releasing on the buried crust is the most likely scenario.
New wind slabs scattered across higher elevation terrain may remain sensitive to human triggering on Friday. Slabs may be most reactive where they have formed over the recent crust.
No recent avalanches have been reported in the region, however stormy conditions have been limiting observations. New snow and elevated winds Thursday likely caused a small uptick in avalanche activity.
Check out these MIN reports for a description of active avalanche conditions in the Bijoux and Torpy areas on Sunday.
10-20 cm of new snow Thursday accumulated on surface crust below about 1200 m and on solar aspects. In exposed areas above the elevation of the crust, it has added to recent wind slabs and otherwise wind-affected snow.
In sheltered areas, 40 - 60 cm of recent snow now overlies a variable layer of surface hoar, crusts, and/or sugary facets. Wind slabs may be surprisingly reactive where they overlie these layers at higher elevations. This issue has been pronounced in the neighbouring central Columbias region.
The middle and lower snowpack is generally strong with no weak layers of concern.
