Avalanche Activity

A dangerous avalanche situation will be encountered over a wide area. Wind slabs and weakly bonded old snow require caution.

The fresh snow of Wednesday and the wind slabs are lying on top of a weakly bonded old snowpack on shady slopes above the tree line. Especially here avalanches can be triggered in the faceted old snow. This applies even in case of a small load. The avalanche prone locations are widespread and are barely recognisable. Medium-sized and, in isolated cases, large avalanches are possible. Remotely triggered avalanches are possible. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches serve as an alarm sign. Weak layers in the old snowpack necessitate defensive route selection.

Snowpack Structure

As a consequence of a strong wind from southerly directions, soft wind slabs formed. These are lying on top of a weakly bonded old snowpack above the tree line. The old snowpack is faceted and weak. This applies especially in shady places that are protected from the wind.

Tendency

Hardly any decrease in avalanche danger. The current avalanche situation calls for caution and restraint.
