Avalanche Activity

The danger of moist and wet avalanches will increase during the day.

The surface of the snowpack will freeze to form a strong crust and will soften during the day. Locally, the night may be cloudy; in that case, the avalanche danger will already be 2—moderate by morning because The surface of the snowpack will only just freeze and will already be soft in the early morning. And so conditions in the mid-mountain range will already be somewhat unfavourable. In the late morning the natural activity of moist and wet avalanches will gradually increase. At low and intermediate altitudes and on very steep slopes small and, in isolated cases, medium-sized moist snow slides and avalanches are to be expected. The conditions are mostly favourable for backcountry touring and other off-piste activities. As a consequence of new snow and a sometimes moderate southeasterly wind, sometimes avalanche prone wind slabs formed. They have formed at high altitudes and in high Alpine regions. The conditions are generally favourable for ski touring.

Snowpack Structure

Colder than expected: The surface of the snowpack has frozen to form a strong crust. New snow and wind slabs are lying on a wet old snowpack. At higher altitudes, snow cover becomes thinner and patchy; it is better at mid-altitudes, which are less exposed to the wind. Below approximately 1900 m hardly any snow is lying. Weak layers exist in the snowpack in particular on steep shady slopes.

Tendency

As a consequence of warming during the day and solar radiation more moist and wet avalanches are possible. Sunshine and high temperatures will give rise to settling of the snowpack. Backcountry tours and ascents to alpine cabins should be concluded timely.
