Wind slabs and weakly bonded old snow require caution.
Avalanches can be released in the weakly bonded old snow. These avalanche prone locations are to be found especially on steep west, north and east facing slopes above the tree line, caution is to be exercised in particular in areas where the snow cover is rather shallow, as well as at transitions from a shallow to a deep snowpack. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Avalanches can reach medium size.
The extensive wind slabs can be released by a single winter sport participant in all aspects. Avalanches can reach quite a large size especially in shady places that are protected from the wind. At high altitude and in the regions exposed to heavier precipitation the avalanche prone locations are more prevalent.

As a consequence of a strong wind from northerly directions, further wind slabs formed in the last three days in particular in gullies and bowls and behind abrupt changes in the terrain. The older wind slabs are lying on soft layers in particular on steep northwest, north and east facing slopes. Precarious weak layers exist deep in the old snowpack especially on shady slopes.
Tendency
Until Wednesday the weather will be clear. The weather conditions will facilitate a slow stabilisation of the snow drift accumulations. Wind slabs and weakly bonded old snow are to be critically assessed.

Avalanches can in some cases be released by a single winter sport participant, in particular on shady slopes above the tree line. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain.
Mostly avalanches are rather small. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
In the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche danger is a little higher.

As a consequence of a strong to storm force wind from northeasterly directions, sometimes avalanche prone wind slabs will form in particular in gullies and bowls and behind abrupt changes in the terrain. The wind slabs will be deposited on soft layers in particular on steep west, north and east facing slopes.
Faceted weak layers exist in the old snowpack especially on shady slopes.

Avalanches can be released by a single winter sport participant. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger, in particular on very steep shady slopes at elevated altitudes. Individual avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain.

The fresh and older wind slabs of the last few days represent the main danger.
As a consequence of a sometimes strong wind from northeasterly directions, further wind slabs formed in particular in gullies and bowls and behind abrupt changes in the terrain. The fresh wind slabs can be released by a single winter sport participant in all aspects above approximately 2200 m. Caution is to be exercised on near-ridge slopes. In little used backcountry terrain the avalanche prone locations are more prevalent. Transitions from a shallow to a deep snowpack are especially unfavourable.
Small and, in isolated cases, medium-sized gliding avalanches are possible.
