The snowpack remains prone to triggering. Fresh wind slabs require caution.
Avalanches can as before be released easily. They can be triggered in the old snowpack and reach large size in isolated cases. Caution is to be exercised in particular on steep west, north and east facing slopes above approximately 1800 m. The avalanche prone locations are barely recognisable, even to the trained eye. As a consequence of the occasionally strong wind, fresh snow drift accumulations will form on Wednesday. These are in some cases prone to triggering on northwest to north to east facing aspects. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Remotely triggered avalanches are possible.
Some snow will fall in some regions. Above approximately 1800 m: The snowpack will be prone to triggering. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes. The fresh wind slabs will be deposited on surface hoar in some places above the tree line. This applies in particular on northwest, north and east facing slopes. Below approximately 1800 m as well as steep sunny slopes: The snowpack is fairly homogeneous and its surface has a crust that is barely capable of bearing a load.
Weak layers in the old snowpack necessitate caution. A sometimes treacherous avalanche situation will persist.
