Recent avalanche observations have been fairly limited due to inclement weather. Having said that, explosives controlled and natural avalanches to size 2.5 were reported having reacted on a variety of aspects. Mostly storm instabilities were observed; however, in some cases avalanches stepped down to persistent weaknesses buried in early February. A size 3 cornice collapse was also reported from the region.

Recent snow accumulations have been variable throughout the region, but mostly moderate daily accumulations and moderate to strong winds have been responsible for extensive wind transport at higher elevations, and recently developed wind slabs now exist at treeline and in the alpine. In the mid snowpack lies the mid-February surface hoar. Buried well over a metre down, this surface hoar may exist in combination with crusts or facets. These persistent weaknesses have remained reactive and are an ongoing concern at all elevations as avalanches may be unexpectedly large and destructive. Large cornices have formed and could also act as a trigger on the slope below.
