The danger of moist and wet avalanches will already be elevated in the early morning. In the event of an overcast night this applies.

The danger of moist and wet avalanches will already be elevated in the early morning. In the event of an overcast night this applies.

Early morning: The conditions are generally favourable for ski touring. If there is cloud cover at night combined with warm air, the avalanche risk will already be 2 (moderate) by the morning because The surface of the snowpack will only just freeze. 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 quickly increase. In particular in starting zones where no previous releases have taken place and on very steep slopes more medium-sized and, in isolated cases, large natural wet avalanches are to be expected. Backcountry tours and ascents to alpine cabins should be concluded timely. As a consequence of new snow and a sometimes moderate southeasterly wind, sometimes avalanche prone wind slabs formed on Monday. They have formed at high altitudes and in high Alpine regions.

The surface of the snowpack is hardly frozen at all. 20 to 40 cm of snow, and even more in some localities, fell on Monday above approximately 2300 m. 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.

The spring-like weather conditions will give rise to settling of the snowpack. As the moisture increases more moist and wet avalanches are possible.
