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 the tree line. The avalanche prone locations are difficult to recognise. As a consequence of the occasionally strong wind, fresh snow drift accumulations will form. 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 in isolated cases.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
Some snow will fall in some regions. The wind will be strong in some regions. 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.
Above the tree line: 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.
Below the tree line 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.
Tendency
Weak layers in the old snowpack necessitate caution. A sometimes treacherous avalanche situation will persist.

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.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
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.
Tendency
Weak layers in the old snowpack necessitate caution. A sometimes treacherous avalanche situation will persist.

Wind slabs and weakly bonded old snow require caution.
Avalanches can be released by a single winter sport participant. This applies especially on steep shady slopes adjacent to ridgelines and in gullies and bowls above the tree line. As a consequence of the occasionally strong wind, fresh snow drift accumulations will form. These are in some cases prone to triggering. In some cases avalanches are medium-sized.
Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
dp.6: cold, loose snow and wind
Some snow will fall. The fresh and older wind slabs are lying on the unfavourable surface of an old snowpack at elevated altitudes. Faceted weak layers exist in the old snowpack.
Low and intermediate altitudes: The snowpack is moist and its surface has a melt-freeze crust that is barely capable of bearing a load.
