Wind and snow transport continue to favour the creation of wind slabs. Investigations over the past few days suggest that the storm left a thick crust and little snow in the southern sectors of the forecast area. Skinning and skiing quality is better in northern sectors.

Snowpack Summary
10 to 20 cm of snow covers the December 11 crust. There are 10 cm of facets between the two crusts. The November 28 crust is between 20 and 40 cm deep, resting on mixed layers of melt-freeze snow in the south of the forecast region and on facets in the north. The height of the snowpack varies between 30 and 70 cm, depending on altitude and wind loading.
Weather Summary
Synopsis: Temperatures will warm up over the next few days, and on Sunday there will probably be an inversion in the mountains. We'll continue to have moderate westerly winds, and we should have some sunshine by the weekend.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Problems
Wind Slabs
Moderate south-westerly and westerly winds favour the growth of wind patches. Snow transport is present in the alpine and at the treeline. Tests showed fracture initiation in the less dense snow layer on the December 11 crust.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
