For those venturing off piste a dangerous avalanche situation will persist.
Large quantities of fresh snow and the wind-drifted snow of the last few days are lying on top of a weakly bonded old snowpack. The fresh snow and the wind slabs formed by the strong to storm force westerly wind remain prone to triggering in all aspects. Winter sport participants can release avalanches easily. Avalanches can in some cases penetrate deep layers and reach large size, in particular on west, north and east facing slopes above the tree line. Remotely triggered avalanches are possible. The avalanche prone locations are numerous, especially in areas close to the tree line, as well as above the tree line. In the regions exposed to heavier precipitation numerous avalanches were reported. Very isolated natural avalanches are further not entirely ruled out. In addition many small and, in isolated cases, medium-sized wet and gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 1800 m.
40 to 80 cm of snow, and even more in some localities, fell in the last few days. Up to intermediate altitudes rain has fallen. Some snow will fall. The wind will be strong for a temporary period. The snowpack will be prone to triggering. Large quantities of fresh snow and the wind-drifted snow are bonding only slowly with the old snowpack. The various wind slabs have bonded insufficiently with each other and the old snowpack. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The rain gave rise to softening of the snowpack at low and intermediate altitudes.
Gradual decrease in avalanche danger.
