Avalanche Activity

Further increase in avalanche danger as a consequence of new snow and wind. In these regions the prevalence and size of the avalanche prone locations will increase by midday.

Above approximately 600 m snow will fall until midday. As a consequence of the moderate to strong southwesterly wind, fresh snow drift accumulations will form. These can in some places be released by a single winter sport participant and reach large size. This applies in particular on steep slopes also in areas close to the tree line, as well as in gullies and bowls, and behind abrupt changes in the terrain. The wind slabs are covered with new snow and therefore barely recognisable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches are a clear indication of a weakly bonded snowpack. Avalanche prone weak layers exist in the snowpack in particular on steep shady slopes. Ski touring and other off-piste activities, including snowshoe hiking, call for extensive experience in the assessment of avalanche danger and great restraint.

Snowpack Structure

As a consequence of heavy snowfall and the moderate to strong southwesterly wind, a very critical avalanche situation developed during the course of the night. The wind has transported the new snow significantly. The new snow and wind slabs are lying on soft layers in particular on wind-protected shady slopes. Intermediate and high altitudes: Individual weak layers exist in the bottom section of the snowpack in particular on very steep shady slopes.
