Kernpunkte

Fresh storm slabs will be primed for human triggers. Stick to simple terrain and stay well away from any large avalanche paths.

    Around 30 to 50 cm of snow sits above a weak layer of surface hoar. This layer is likely best preserved in shaded and sheltered areas between 1700 m and 2000 m.

Avalanche Summary

No avalanches were reported in the region on Wednesday. However, fresh storm slabs reactive to human triggers are expected to form on Friday.

Snowpack Summary

The forecast new snow will cover a variety of snow surfaces. These include crusts on all but northerly aspects, wind-pressed surfaces on northerly aspects in the alpine, and a mixture of surface hoar (weak feathery crystals) and surface facets (sugary grains) in terrain sheltered from wind/sun at treeline and below.Around 30 to 50 cm down is a melt-freeze crust to mountain top on southerly aspects, a crust below around 1700 m on all aspects, and feathery surface hoar in areas sheltered by the wind/sun at treeline elevations. The remainder of the snowpack is currently well-settled and strong in most locations.
