Avalanche Summary

A few size 1-1.5 loose dry avalanches have been reported over the last few days.

Snowpack Summary

In general, dry new snow overlies a strong snowpack. You may encounter wind slabs near ridge tops which are sensitive to the weight of a person. As winds shift from south-westerly to northerly, be alert to the possibility of wind slabs on all aspects. Down about 70-100 cm in some areas, a thin crust/facet layer is generally giving hard, resistant results in snowpack tests.The lower snowpack is reportedly well settled. The early December weak layer (about 130-150 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.
