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.
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 unfavourable.
