Along the border with Switzerland above approximately 2500 m in some localities danger level 4 (high) will be reached.

As a consequence of new snow and a sometimes strong wind from southerly directions, sometimes large wind slabs formed in the last three days adjacent to ridgelines and in pass areas as well as above the tree line. Here they will increase in size additionally until Sunday. They can be released easily or naturally in all aspects. In particular at high altitudes and in high Alpine regions these avalanche prone locations are more widespread and the danger is greater. During the day: Natural avalanches are further to be expected. The avalanches can be released in the new snow and wind slab layers and reach quite a large size. As a consequence of the precipitation moist and wet avalanches are possible.

Saturday: Above approximately 2100 m more snow fell. This applies in particular in the afternoon. Here rain fell up to 2000 m. The southerly wind has transported the new snow significantly. In some places new snow and wind slabs are lying on soft layers. The upper section of the snowpack is unfavourably layered. Sunday: Above approximately 2200 m 20 to 50 cm of snow will fall. The sleet will give rise to a loss of strength within the snowpack below approximately 2400 m.

Dry and moist avalanches are possible in some places.
