New snow and weakly bonded old snow require caution.
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 on west, north and east facing slopes above the tree line. The avalanche prone locations are numerous, especially in areas close to the tree line, as well as above the tree line. In addition individual wet and gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 1800 m.
Some snow will fall. The wind will be strong in some cases. The wind will transport the snow. Further wind slabs will form. 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 snow sport conditions outside marked and open pistes remain dangerous.
