Snowpack Structure

As a consequence of new snow and a strong to storm force wind from northerly directions, avalanche prone wind slabs formed in particular in gullies and bowls and behind abrupt changes in the terrain. The fresh wind slabs are lying on the unfavourable surface of an old snowpack in all aspects and generally above the tree line. Distinct weak layers exist in the bottom section of the snowpack on steep shady slopes. This applies especially above the tree line.

Tendency

The avalanche danger will persist.

Avalanche Activity

Fresh wind slabs represent the main danger.

The wind slabs represent the main danger. Avalanches can be released by small loads, especially above the tree line, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Precarious weak layers exist in the old snowpack on very steep shady slopes. These avalanche prone locations are to be found in particular in northwest to north to northeast facing aspects. Medium-sized avalanches are possible adjacent to ridgelines and in gullies and bowls. They can also release deeper layers of the snowpack and reach quite a large size. Remotely triggered avalanches are possible. In particular slopes that have been little used this winter thus far where weaknesses exist in the old snowpack are especially dangerous.
