New snow and wind slabs during the course of the night.

Above approximately 1500 m snow will fall until Sunday. The fresh snow as well as the sometimes large wind slabs to be found above all in gullies and bowls and behind abrupt changes in the terrain can be released easily or naturally above approximately 2200 m. On very steep slopes the avalanches can be triggered in the various layers of new snow and reach large size in some cases. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection.

30 to 40 cm of snow will fall until Saturday above approximately 1500 m. Adjacent to ridgelines and in gullies and bowls sometimes large wind slabs will form. (--), in particular on steep, rather lightly snow-covered shady slopes. In the last three days on very steep slopes large and, in isolated cases, very large avalanches were reported. Sunshine and high temperatures gave rise to increasing consolidation of the snowpack over a wide area in particular on sunny slopes below approximately 3000 m. Especially sunny slopes as well as low and intermediate altitudes: The upper section of the snowpack is largely stable and its surface has a crust. Transitions from a shallow to a deep snowpack where weaknesses exist in the old snowpack are especially precarious.

As a consequence of the new snow the avalanche prone locations will become more prevalent during the night.
