Stability: poor · Frequency: few
Weak layers in the lower part of the snowpack represent the main danger.
The avalanche prone locations are to be found in particular in steep terrain at high altitudes and in high Alpine regions and in gullies and bowls, where weak layers exist in the old snowpack or where melt-freeze crusts have formed are unfavourable. This applies especially along the border with France. The avalanches can be released, mostly by large loads in isolated cases and reach medium size. In other regions the avalanche prone locations are more rare and the danger is lower.
Sunny slopes and low and intermediate altitudes: The snowpack is fairly homogeneous and its surface has a melt-freeze crust. Shady slopes and in places that are protected from the wind: The snowpack is soft and has a loosely bonded surface. Large-grained weak layers exist in the bottom section of the snowpack here.
Until Monday the weather will be mild. The weather conditions will foster a strengthening of the snowpack.
