A mostly favourable avalanche situation will prevail.
In some localities increase in danger of moist and wet avalanches as a consequence of warming during the day. The avalanche prone locations are to be found in particular on very steep sunny slopes at elevated altitudes.
Snowpack
dp.10: springtime scenario
In all altitude zones less snow than usual is lying. As a consequence of highly fluctuating temperatures and solar radiation the snowpack consolidated. These weather conditions as the day progresses will give rise to increasing moistening of the snowpack in particular on steep sunny slopes.
Tendency
The avalanche danger will persist.

A clear night will be followed in the early morning by favourable conditions generally.
As a consequence of warming during the day and solar radiation wet loose snow avalanches are possible, but they can reach medium size in isolated cases, especially on very steep sunny slopes below approximately 3000 m. Weak layers in the old snowpack can be released in very isolated cases. The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m. Avalanches can reach medium size in isolated cases.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Outgoing longwave radiation during the night will be good over a wide area. Especially on steep sunny slopes, a partially stable melt-freeze crust formed. Sunshine and high temperatures will give rise as the day progresses to a loss of strength within the snowpack in some cases on very steep sunny slopes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The fresh wind slabs are lying on soft layers especially on shady slopes in high Alpine regions.
Tendency
A clear night will be followed in the early morning by quite favourable conditions generally. Gradual increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.
