A large avalanche cycle occurred on Tuesday, ending on Wednesday. Numerous large (size 2-3) storm slab avalanches were reported.

Surface hoar crystals continue to grow in sheltered areas, and some sugary facets are forming on the surface too.

Areas exposed to the wind in the alpine and at treeline have been heavily affected. With sastrugi and hard surfaces.

At treeline and below, there is a breakable surface crust.

The mid and lower snowpack is well settled with no layers of concern.

Treeline snow depths throughout the region range from 250 cm to 350 cm.
