As a consequence of heavy snowfall and the moderate to strong southwesterly wind, fresh snow drift accumulations formed. These can be released by a single winter sport participant and reach large size. This applies in particular on steep west, north and east facing slopes in particular above the tree line, as well as in gullies and bowls, and behind abrupt changes in the terrain. Shooting cracks when stepping on the snowpack and natural avalanches are a clear indication of a weakly bonded snowpack. Little snow will fall in some localities. The avalanche prone locations are barely recognisable because of the poor visibility. Ski touring and other off-piste activities, including snowshoe hiking, call for careful route selection.
40 to 50 cm of snow fell on Wednesday above approximately 1400 m. The wind has transported some snow. As a consequence of heavy snowfall and the moderate to strong southwesterly wind, snow drift accumulations formed. The snowpack is soft; its surface consists of loosely bonded snow. This applies in shady places that are protected from the wind also at low and intermediate altitudes. Especially steep sunny slopes: As a consequence of rising temperatures and solar radiation a crust formed on the surface on Thursday.
