Stability: very poor · Frequency: many
Above the tree line a precarious avalanche situation will be encountered over a wide area.
The fresh snow and the wind slabs formed during the snowfall are lying on top of a weakly bonded old snowpack on west, north and east facing slopes above the tree line. Especially here avalanches can be triggered in the faceted old snow. This applies even in case of a small load. The avalanche prone locations are widespread and are barely recognisable. Mostly avalanches are medium-sized. Remotely triggered avalanches are possible. Individual natural avalanches are further possible. The number and size of avalanche prone locations will increase with altitude. Afternoon: As a consequence of solar radiation loose snow avalanches are possible.
30 cm of snow, and even more in some localities, has fallen since Saturday above approximately 1500 m. As a consequence of a gusty wind from southerly directions, soft wind slabs formed. These are lying on top of a weakly bonded old snowpack above the tree line. The old snowpack is faceted and weak. This applies especially in shady places that are protected from the wind. The old snowpack will be subject to considerable local variations.
The new snow and wind slabs remain prone to triggering.
