Stability: poor · Frequency: few
Weak layers in the old snowpack necessitate caution.
Distinct weak layers in the old snowpack necessitate defensive route selection. Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants in particular above approximately 1900 m. Avalanches can penetrate even deep layers. The avalanche prone locations are clearly recognisable to the trained eye. Remotely triggered avalanches are possible in isolated cases.
The old snowpack will be in most cases subject to considerable local variations. Towards its base, the snowpack is faceted and weak. This applies in particular on steep shady slopes above approximately 1900 m. Remotely triggered avalanches are possible in isolated cases. In steep terrain there is a danger of falling on the icy crust.
