On Thursday several size 1-1.5 avalanches could be easily ski cut behind ridgecrests on all aspects in the new snow. A few days ago, a large human-triggered avalanche was reported near Corbin in the Flathead Range in an area where wind had firmed up the surface snow and where sugary facets were present lower down in the snowpack. There's lots of loose snow available for redistribution, so if the wind picks up, expect an increase in wind slab avalanche activity.

Up to 50 cm of low density snow has recently fallen, which is now available to be redistributed by mostly moderate westerly winds. The new snow sits above a variety of surfaces including old hard wind slabs and surface hoar. The cold weather in early December left several layers of weak surface hoar and facets which are now buried 50-80 cm deep. These layers are expected to be more in reactive in areas where the overlying slab has gained cohesion with wind or settlement. A thick crust rain crust from mid-November is near the bottom of the snowpack and remains well bonded to the surrounding snow.
