All the recent storm snow may take a bit of time to strengthen. Conservative decision-making is recommended.

A natural avalanche cycle occurred on Thursday into Friday. Large (size 2 to 3) storm slab avalanches were triggered naturally and by explosives on Friday within the storm snow.

Around 60 to 80 cm of snow fell in the region on Thursday and Friday above 1500 m. This new snow has formed touchy storm slabs. The snow fell with strong southwest winds, so expect the deepest deposits in lee terrain features near ridges at higher elevations. In sheltered areas around treeline, this snow overlies a weak layer of feathery surface hoar crystals. Below 1500 m, the precipitation largely fell as rain, so expect wet snow that will freeze into a hard crust once temperatures cool.In the east side of the region near Corbin, a persistent weak layer that formed in early December may still be found 80 to 120 cm deep. This layer mostly consists of sugary faceted snow with some isolated areas also containing feathery surface hoar crystals. While professionals are still tracking this layer, it has not been reactive for some time now.Near the bottom of the snowpack lies a mix of crusts and facets that formed in late October/early November. This layer may only be an issue on steep slopes where the snowpack is shallow.
