Outside marked and open pistes a precarious avalanche situation will prevail.
The fresh snow as well as the widespread wind slabs are lying on top of a weakly bonded old snowpack in particular on west, north and east facing slopes above the tree line. Avalanches can be released easily and reach medium size. Remotely triggered avalanches are possible. The avalanche prone locations are widespread and are barely recognisable. The number and size of avalanche prone locations will increase with altitude. Caution is to be exercised in gullies and bowls, and behind abrupt changes in the terrain. Field observations and avalanches triggered by explosives confirm a precarious avalanche situation. Caution and restraint are required.
10 to 20 cm of snow has fallen. As a consequence of southwesterly wind, wind slabs formed on Wednesday. The new snow and wind slabs are lying on top of a weakly bonded old snowpack. Distinct weak layers exist in the old snowpack. This applies especially on wind-protected west, north and east facing slopes.
Hardly any decrease in avalanche danger.
