Highlights

Strong winds will probably make the alpine an unpleasant place to be on Thursday. Watch out for overhead exposure if you end up hiding out at treeline. Natural avalanches will become increasingly likely through the day.

Avalanche Summary

Natural and artificially triggered avalanche activity was reported from across the region on Wednesday.  Cornices remain large and fragile and would likely collapse under the weight of a person.

Snowpack Summary

Between 40 and 80cm of new snow and strong winds have formed reactive soft slabs in steep, open, and unsupported alpine and treeline features. The upper snowpack sits on a widespread crust on all but high elevation north facing slopes. Cornices are large and weak.  The mid-pack is generally well settled.
