Wind slabs and weakly bonded old snow require caution.

Wind slabs and weakly bonded old snow require caution.

The somewhat older wind slabs can be released by a single winter sport participant in some cases on west to north to east facing aspects, in particular above approximately 2200 m. Slopes adjacent to ridgelines are especially unfavourable. Mostly avalanches are medium-sized. Additionally avalanches can also be released in deep layers. Such avalanche prone locations are to be found on steep, little used shady slopes above approximately 2200 m and on steep sunny slopes above approximately 2500 m. Especially transitions from a shallow to a deep snowpack are unfavourable. Backcountry touring and other off-piste activities call for a certain restraint.

Wind slabs are lying on weak layers in particular on west to north to east facing aspects above the tree line. The more recent wind slabs will be deposited on surface hoar in some places, in particular on the Main Alpine Ridge and to the north. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2500 m.

Fresh wind slabs require caution. The old snowpack remains in some cases prone to triggering. As a consequence of new snow and a gathering storm force northwesterly wind, sometimes avalanche prone wind slabs will form on Monday. For this reason the avalanche danger will increase during the day, in the regions exposed to a lot of wind in particular in the northwest and.
