A dangerous avalanche situation will prevail. The danger exists in particular in alpine snow sports terrain.
The new snow and wind slabs of the last few days are lying on top of a weakly bonded old snowpack. The fresh snow of Saturday and the wind slabs formed by the strong to storm force westerly wind remain prone to triggering in all aspects above the tree line. Winter sport participants can release avalanches easily. Avalanches can in some cases penetrate deep layers and reach large size. This applies on west, north and east facing slopes. The avalanche prone locations are numerous, especially in areas close to the tree line, as well as above the tree line. Very isolated natural avalanches are further not entirely ruled out. In addition some wet and gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 1800 m.
A lot of snow fell in the last few days in some regions. Some snow will fall on Monday. The wind will be strong in some cases. The wind will transport the new snow. Further wind slabs will form. Up to intermediate altitudes rain has fallen. The snowpack will be prone to triggering over a wide area. The new snow and wind slabs are lying on top of a weakly bonded old snowpack. Somewhat older wind slabs are lying on surface hoar. Distinct weak layers exist in the bottom section of the old snowpack. This applies in particular on west, north and east facing slopes above the tree line. The weather conditions as the day progresses will give rise to gradual and thorough wetting of the snowpack at low and intermediate altitudes, especially on steep sunny slopes.
Gradual decrease in avalanche danger.
