New snow, wind slabs and old snow require caution. The conditions are precarious for backcountry touring and other off-piste activities.
Slab avalanches and loose snow slides are the main danger. Outside marked and open pistes a dangerous avalanche situation will prevail.
The fresh snow of yesterday and the wind slabs are lying on the unfavourable surface of an old snowpack above the tree line. In particular on wind-loaded slopes avalanches can be released easily and reach large size in isolated cases. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible. Distinct weak layers in the lower part of the snowpack can be released even now easily by individual winter sport participants in particular on west, north and east facing slopes. This applies in particular above the tree line. The avalanche prone locations are numerous and are barely recognisable, even to the trained eye. The number and size of avalanche prone locations will increase with altitude. Caution and restraint are required.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
The new snow and wind slabs of Tuesday are lying on surface hoar above the tree line. Distinct weak layers exist in the old snowpack. This applies especially on west, north and east facing slopes. During the day: Over a wide area 5 to 15 cm of snow, and even more in some localities, will fall above approximately 1200 m.
Tendency
Night: In some localities up to 15 cm of snow will fall above approximately 1200 m. The avalanche danger will increase but remain within the current danger level.
