Weakly bonded old snow requires caution. New snow and wind slabs require caution.
Avalanches can in some cases be released in the old snowpack and reach medium size, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Remotely triggered avalanches are possible in isolated cases. The wind slabs can be released by a single winter sport participant in isolated cases above approximately 2200 m. Such avalanche prone locations are covered with new snow and are therefore difficult to recognise. Caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can reach medium size. In addition small and medium-sized loose snow avalanches are possible, in the event of prolonged bright spells especially on extremely steep slopes.
The old snowpack will be weakly bonded in some places, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes in high Alpine regions. Some snow will fall in some regions. The sometimes strong wind has transported the fresh and old snow. In some cases the various wind slabs have bonded still only poorly together.
New snow and weakly bonded old snow are to be assessed with care and prudence.
