Highlights

There is variability across the region due to recent wind effects and the existence of buried surface hoar in some spots. Investigate your local snowpack.

    Recent winds have shifted snow into slabs behind ridges and ribs. These could be triggered by the weight of a person.

Avalanche Summary

Several small loose dry and very soft slab avalanches have been reported over the last couple of days.

Snowpack Summary

30-50 cm recent dry snow overlies a generally strong snowpack. Some operators report surface hoar buried down about 10-15 cm. You may encounter wind slabs which are sensitive to the weight of a person near ridge tops. Recent storm snow is sluffing readily in steep terrain. One operator near Kamloops is reporting a hard slab sitting on a layer of surface hoar buried down 30-50 cm. This appears to be an outlier, but I would take extra time to investigate the snowpack if you are in the far west of the region.The lower snowpack is reportedly well settled. The early December weak layer (about 80-150 cm down) is spotty in distribution, but where it does exist, still gives hard, sudden results, meaning it is unlikely to be triggered, but could produce a very large avalanche.
