Stability: poor · Frequency: some
The snowpack will be quite prone to triggering. The fresh wind slabs can be released very easily in particular on north to east to south facing aspects. The avalanche prone locations are to be found especially on steep shady slopes above the tree line. Weak layers in the old snowpack necessitate caution and restraint. As a consequence of new snow and wind avalanches are possible, even quite large ones.

Avalanches can in some places be released easily. New snow and wind slabs require caution, especially on steep west, north and east facing slopes above the tree line as well as in areas close to the tree line. Avalanches can penetrate down to the ground and reach large size in some cases. The avalanche prone locations are numerous difficult to recognise. 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.
The new snow and wind slabs are lying on surface hoar in particular on wind-protected shady slopes. Towards its base, the snowpack is faceted and weak. Avalanches can be released in deeper layers very easily. In addition the wind slabs adjacent to ridgelines and in gullies and bowls are capable of being triggered.
