The snowpack remains prone to triggering. Fresh wind slabs require caution.
Avalanches can as before be released easily. Mostly they are medium-sized. Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line. The avalanche prone locations are barely recognisable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. As a consequence of the occasionally strong wind, fresh snow drift accumulations will form. These are in some cases prone to triggering in particular on northwest to north to east facing aspects.
Some snow will fall in some regions. The wind will be strong over a wide area. 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. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes above approximately 2000 m. Below approximately 2000 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.
