Avalanche Activity

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

As a consequence of a moderate to strong southwesterly wind, further wind slabs will form in the course of the day. They can be released by a single winter sport participant and reach 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. Down to low altitudes snow will fall from 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 caution and restraint.

Snowpack Structure

Down to low altitudes snow will fall from the afternoon. As a consequence of the moderate to strong southwesterly wind, fresh snow drift accumulations will form. The snowpack is soft; its surface consists of loosely bonded snow. This applies in shady places that are protected from the wind at low and intermediate altitudes.

Tendency

Increase in avalanche danger as a consequence of new snow and wind.
