Persistent weak layers
- Above 2,600 m
Weakly bonded old snow at elevated altitudes. Wind slabs require caution.

The near-surface layers of the snowpack can still be released in isolated cases by winter sport participants, especially on very steep north, northeast and east facing slopes between approximately 2700 and 3100 m, but in isolated cases also on very steep sunny slopes above approximately 2600 m. On the Main Alpine Ridge such avalanche prone locations are more prevalent. Mostly avalanches are medium-sized. In addition the wind slabs adjacent to ridgelines and at elevated altitudes are capable of being triggered in isolated cases still. They are to be evaluated with care and prudence in particular in very steep terrain. As the moisture increases individual moist snow slides are possible.
Faceted weak layers exist in the top section of the snowpack, especially on north, northeast and east facing slopes between approximately 2700 and 3100 m, as well as on sunny slopes above approximately 2600 m. Some snow will fall in some regions. The sometimes strong wind will transport only a little snow. The wind slabs are lying on soft layers in particular on very steep shady slopes at elevated altitudes. The surface of the snowpack will cool hardly at all during the overcast night. The weather conditions will give rise to slight moistening of the snowpack.
Some snow will fall on Wednesday over a wide area. The old snowpack remains prone to triggering at elevated altitudes. In some regions increase in danger of dry avalanches in particular at elevated altitudes.
