Avalanche Activity

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

Early morning: The surface of the snowpack will freeze to form a strong crust. The conditions are generally favourable for ski touring. From the middle of the day the natural activity of avalanches will 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 possible. Backcountry tours and ascents to alpine cabins should be concluded timely.

Snowpack Structure

20 to 40 cm of snow, and even more in some localities, fell on Monday above approximately 2300 m. The weather conditions gave rise to rapid settling of the snowpack. 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

Outgoing longwave radiation during the night will be reduced in some case. As the moisture increases more moist and wet avalanches are possible.
