Persistent weak layers
- Above 2,500 m
Weakly bonded old snow represents the main danger. Wind slabs at elevated altitudes.

Avalanches can be released in near-surface layers by a single winter sport participant, in particular on very steep sunny slopes above approximately 2500 m, in isolated cases also on very steep shady slopes. On the Main Alpine Ridge such avalanche prone locations are more prevalent. Avalanches can reach large size in isolated cases. In addition the wind slabs of the last few days adjacent to ridgelines and at elevated altitudes are capable of being triggered in some cases still. They are to be evaluated with care and prudence in particular in very steep terrain. On extremely steep sunny slopes individual loose snow slides are possible.
Faceted weak layers exist in the top section of the snowpack, especially on sunny slopes above approximately 2500 m, in isolated cases also on shady slopes at elevated altitudes. As a consequence of the occasionally strong wind, fresh snow drift accumulations formed during the last few days. These are lying on soft layers in particular on very steep shady slopes at elevated altitudes. The solar radiation will give rise to gradual moistening of the snowpack in particular on sunny slopes at intermediate altitudes.
On Wednesday it will be cold. The wind will be moderate. The snowpack remains prone to triggering at elevated altitudes.
