Increase in avalanche danger as a consequence of new snow and wind.
As a consequence of new snow and a sometimes storm force southwesterly wind, further wind slabs will form in particular in gullies and bowls and behind abrupt changes in the terrain. The fresh wind slabs will become increasingly prone to triggering. Individual natural avalanches are possible. In the regions exposed to heavier precipitation this applies in particular. Caution is to be exercised in particular on steep shady slopes in areas close to the tree line and above the tree line. At high altitude and in the regions exposed to heavier precipitation these avalanche prone locations are more prevalent. The fresh wind slabs are barely recognisable because of the poor visibility.
Avalanches can additionally be released in the weakly bonded old snow. These avalanche prone locations are to be found especially on very steep shady slopes above approximately 2400 m, 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. Avalanches can reach large size in isolated cases.
Snowpack
dp.6: cold, loose snow and wind
20 to 40 cm of snow, and even more in some localities, will fall until Wednesday. The wind will be strong to storm force. The southwesterly wind will transport the new snow. The wind slabs will be deposited on a weakly bonded old snowpack in particular on steep northwest, north and east facing slopes.
Shady slopes: The old snowpack consists of faceted crystals. The fresh wind slabs will be deposited on soft layers.
Steep sunny slopes: The fresh wind slabs will be deposited on a crust.
Tendency
Fresh wind slabs require caution.

Gliding snow
Increase in avalanche danger as a consequence of new snow and wind, in the regions exposed to a lot of wind caution is to be exercised in particular.
The fresh wind slabs represent the main danger. As a consequence of a strong to storm force wind from westerly directions, avalanche prone wind slabs will form in the course of the day in particular in gullies and bowls and behind abrupt changes in the terrain. The wind slabs can be released easily, even by a single winter sport participant, in particular on northwest to north to east facing aspects. Caution is to be exercised in particular on near-ridge slopes above approximately 2200 m. The avalanche prone locations are sometimes covered with new snow and are difficult to recognise. During the day: As a consequence of the sometimes strong westerly wind the avalanche prone locations will become more prevalent.
An increasing number of mostly small gliding avalanches are possible as a consequence of the new snow. Areas with glide cracks are to be avoided.
Avalanches can additionally in very isolated cases be released in the weakly bonded old snow. These avalanche prone locations are to be found especially on very steep shady slopes above approximately 2400 m, caution is to be exercised in particular at transitions from a shallow to a deep snowpack. Avalanches can reach medium size.
Snowpack
dp.6: cold, loose snow and wind
Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall. As a consequence of the occasionally strong westerly wind, fresh snow drift accumulations will form in the course of the day.
Shady slopes: The old snowpack consists of faceted crystals. The fresh wind slabs are lying on soft layers.
Steep sunny slopes: The fresh wind slabs will be deposited on a crust.
Tendency
Fresh wind slabs are to be evaluated critically.

Slight increase in avalanche danger as a consequence of new snow and wind. Only a small amount of snow is lying for the time of year.
Avalanches can be released by a single winter sport participant, 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. In isolated cases avalanches are medium-sized. 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
dp.6: cold, loose snow and wind
Over a wide area up to 15 cm of snow, and even more in some localities, will fall until Wednesday. The wind will be strong to storm force. The southwesterly wind will transport the new snow. The wind slabs will be deposited on a weakly bonded old snowpack in particular on steep northwest, north and east facing slopes.
Shady slopes: The old snowpack consists of faceted crystals. The fresh wind slabs will be deposited on soft layers.
Steep sunny slopes: The fresh wind slabs will be deposited on a crust. The snowpack will be subject to considerable local variations over a wide area.
Tendency
Fresh wind slabs require caution.
