Storm slabs will be deepest and most reactive in places the wind has blown the snow into deeper deposits.

• A few small (up to size 1.5) avalanches were reported in the region on northerly aspects in the alpine and at treeline.

The upper 30 to 60 cm of the snow pack is an accumulation of snow from the last few days, with up to 15 cm more falling throughout the day.

Moderate southwesterly winds will redistribute the recent storm snow, continuing to build slabs that are likely to be deeper and more reactive on wind-loaded lee slopes near ridgetops.

The prominent mid-December crust is buried up to 110 cm deep and extends to 2200 m. Triggering the crust is considered unlikely, except with large loads or in thin snowpack areas.
