In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2600 m.
As a consequence of new snow and a strong wind from easterly directions, wind slabs will form from the middle of the day in gullies and bowls and behind abrupt changes in the terrain. These can in some cases be released, even by a single winter sport participant, but they will be small in most cases. Caution is to be exercised in particular on shady slopes above the tree line in the regions exposed to heavier precipitation. Avalanches can in isolated cases penetrate deep layers and reach medium size, especially at elevated altitudes.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
In some regions up to 15 cm of snow will fall. The wind will be strong for a temporary period in some regions. The fresh wind slabs will be deposited on the unfavourable surface of an old snowpack on wind-protected shady slopes. The old snowpack will be subject to considerable local variations.
Tendency
The conditions will foster a gradual stabilisation of the snow drift accumulations.

As a consequence of the wind the wind slabs will increase in size in the afternoon.

As the day progresses as a consequence of new snow and wind there will be only a slight increase in the avalanche danger.
The avalanche danger will increase during the day, reaching danger level 2 (moderate). Especially in the regions with a lot of snow avalanches can be triggered in the weakly bonded old snow. This applies especially on steep shady slopes above the tree line. Avalanches can in isolated cases reach medium size. Mostly the avalanches are otherwise small. As a consequence of new snow and a moderate to strong wind from easterly directions, sometimes avalanche prone wind slabs will form in particular adjacent to ridgelines and in gullies and bowls. 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.
Snowpack
Over a wide area up to 20 cm of snow, and even more in some localities, will fall above approximately 1200 m. The new snow will be deposited on the unfavourable surface of an old snowpack. Shady slopes above approximately 2400 m: Faceted weak layers exist in the bottom section of the snowpack.
Below approximately 2400 m: The snowpack is largely stable. Hardly any snow is lying on south facing slopes.
The snowpack will be generally subject to considerable local variations. Only a small amount of snow is lying for the time of year in all altitude zones.
Tendency
The conditions will foster a gradual stabilisation of the snow drift accumulations.
