High avalanche danger will prevail. The off-piste conditions are dangerous.
The large quantity of fresh snow and the extensive wind slabs are very prone to triggering. Single winter sport participants can release avalanches in many places, including large ones. The avalanche prone locations are to be found in all aspects above the tree line. Individual avalanche prone locations are to be found also in areas close to the tree line. As a consequence of new snow and stormy weather the prevalence and size of these avalanche prone locations will increase in the afternoon. Already in the early morning, individual, then as the precipitation becomes heavier numerous natural avalanches are to be expected. They can in isolated cases penetrate near-ground layers of the snowpack. This applies in particular above approximately 2200 m. Medium-sized gliding avalanches are possible on steep grassy slopes. They can be released at any time of day or night.
Over a wide area 30 to 60 cm of snow has fallen since Saturday. 10 to 20 cm of snow will fall until the evening. The wind will be strong to storm force adjacent to ridgelines. The various wind slabs have bonded poorly with each other and the old snowpack. Isolated avalanche prone weak layers exist in the bottom section of the old snowpack above approximately 2200 m.
The avalanche danger will persist. As a consequence of new snow and stormy weather more large and, in isolated cases, very large natural avalanches are possible.
