Significant increase in avalanche danger in the course of the day. The snow sport conditions outside marked and open pistes are unfavourable.
As a consequence of new snow and strong wind more frequent natural avalanches are to be expected as the day progresses, even large ones. Single winter sport participants can release avalanches very easily, including large ones. Avalanche prone locations for dry avalanches are to be found in particular on steep west, north and east facing slopes above the tree line, also on steep shady slopes in areas close to the tree line.
The avalanche prone locations are barely recognisable because of the poor visibility. Extensive experience in the assessment of avalanche danger and great restraint are important.
Snowpack
dp.1: deep persistent weak layer dp.2: gliding snow
Over a wide area 30 to 50 cm of snow, and even more in some localities, will fall. As a consequence of a strong to storm force wind from southwesterly directions, deep wind slabs will form. The fresh wind slabs are lying on top of a weakly bonded old snowpack in particular on west to north to east facing aspects. They are lying on soft layers on shady slopes.
Above the tree line snow depths vary greatly, depending on the infuence of the wind.

The snow sport conditions outside marked and open pistes are to some extent unfavourable.
As a consequence of new snow and a strong to storm force southwesterly wind, extensive wind slabs will form over a wide area. Single winter sport participants can release avalanches easily. Natural avalanches are possible as the day progresses, in particular medium-sized ones. Avalanche prone locations for dry avalanches are to be found in particular on steep west, north and east facing slopes above the tree line, also on steep shady slopes in areas close to the tree line.
The avalanche prone locations are barely recognisable because of the poor visibility. Caution and restraint are advisable.
Snowpack
dp.1: deep persistent weak layer
Over a wide area 20 to 30 cm of snow, and even more in some localities, will fall. As a consequence of a strong to storm force wind from southwesterly directions, extensive wind slabs will form. The fresh wind slabs are lying on top of a weakly bonded old snowpack in particular on west to north to east facing aspects. They are lying on soft layers on shady slopes.

Fresh wind slabs represent the main danger.
As a consequence of new snow and a strong to storm force southwesterly wind, further wind slabs will form. Avalanche prone locations are to be found in particular on steep west, north and east facing slopes above the tree line. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls.
The avalanche prone locations are barely recognisable because of the poor visibility.
Snowpack
dp.6: cold, loose snow and wind
Over a wide area 10 to 20 cm of snow will fall. As a consequence of a strong to storm force wind from southwesterly directions, rather small wind slabs will form. The fresh wind slabs are lying on soft layers in particular on shady slopes.
Above the tree line snow depths vary greatly, depending on the infuence of the wind.
