Avalanche Activity

As a consequence of the sometimes strong wind the avalanche prone locations will become more prevalent as the day progresses.

As a consequence of a sometimes moderate wind, further wind slabs will form in the course of the day. They can be released, even by small loads in isolated cases and reach dangerously large size. This applies in particular on steep slopes above the tree line, as well as in gullies and bowls, and behind abrupt changes in the terrain. Some snow will fall in the afternoon. The avalanche prone locations are barely recognisable because of the poor visibility. Ski touring and other off-piste activities, including snowshoe hiking, call for defensive route selection.

Snowpack Structure

The moderate wind will transport the snow. The fresh wind slabs will be deposited on unfavourable layers. The snowpack is soft; its surface consists of loosely bonded snow. This applies in shady places that are protected from the wind also at low and intermediate altitudes. Faceted weak layers exist in the snowpack on steep shady slopes.
