Fresh wind slabs require caution. A clear night will be followed in the early morning by quite favourable conditions generally.
As a consequence of a moderate to strong wind from southerly directions, wind slabs will form in particular adjacent to ridgelines. This applies in particular at high altitudes and in high Alpine regions. The fresh wind slabs are mostly small but can be released easily.
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.
Snowpack
dp.6: cold, loose snow and wind dp.10: springtime scenario
The fresh wind slabs are lying on soft layers on shady slopes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes.
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.
Tendency
Fresh wind slabs require caution. Gradual increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.

A clear night will be followed in the early morning by quite favourable conditions generally, but the danger of wet and gliding avalanches will increase later.
On steep grassy slopes small to medium-sized gliding avalanches are possible. This applies in particular in the west and below approximately 2400 m.
As a consequence of warming during the day and solar radiation more wet loose snow avalanches are possible, even medium-sized ones, in particular on very steep sunny slopes.
Snowpack
dp.10: springtime scenario
Since Sunday the weather has been mild. As a consequence of mild temperatures and solar radiation a crust formed on the surface at the weekend, especially on sunny slopes. Outgoing longwave radiation during the night will be good. Steep sunny slopes, high altitudes: The surface of the snowpack will soften during the day.
Only a little snow is now lying on south facing slopes.
Tendency
A generally favourable avalanche situation will prevail. Slight increase in danger of moist and wet avalanches as a consequence of warming.

As a consequence of a moderate to strong wind from southerly directions, mostly small wind slabs will form in particular adjacent to ridgelines. This applies in particular at high altitudes and in high Alpine regions. 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.

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. As a consequence of wind from southerly directions, mostly small wind slabs will form. The wind will transport only a little snow. The fresh wind slabs are lying on soft layers in particular on shady slopes.
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.
