As the penetration by moisture increases natural avalanches are possible at any time. Fresh wind slabs in the high Alpine regions.
The danger of wet avalanches will persist. The avalanche prone locations are to be found in all aspects below approximately 2800 m. Especially on very steep west, north and east facing slopes natural avalanches are possible as the penetration by moisture increases. These can release the saturated snowpack and reach large size in the regions with a lot of snow. In some cases, the avalanches can reach areas without any snow cover in steep gullies.
Fresh wind slabs can be released by a single winter sport participant in isolated cases in particular on very steep shady slopes above approximately 2800 m. Such avalanche prone locations are to be found adjacent to ridgelines and in gullies and bowls.
The conditions are unfavourable for backcountry touring.
Snowpack
dp.10: springtime scenario dp.3: rain
The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. Up to high altitudes rain will fall in some localities. The weather conditions will give rise to increasing and thorough wetting of the snowpack below approximately 2800 m. This situation will give rise to a loss of strength within the snowpack especially on west, north and east facing slopes.
High Alpine regions: 10 to 20 cm of snow, and even more in some localities, has fallen. In some localities up to 10 cm of snow, and even more in some localities, will fall on Wednesday. As a consequence of new snow and a sometimes strong southerly wind, rather small wind slabs will form. These are lying on soft layers on very steep shady slopes.
Tendency
Gradual increase in danger of wet avalanches as the precipitation becomes more intense.

Wet and gliding snow represent the main danger.
From the late morning as a consequence of warming during the day and solar radiation there will be a gradual increase in the danger of wet avalanches. Avalanches can in some places be released, even by a single winter sport participant. The avalanche prone locations are to be found on very steep shady slopes below approximately 2600 m and on very steep sunny slopes in all altitude zones. Especially in starting zones where no previous releases have taken place individual small and medium-sized natural avalanches are possible.
Gliding avalanches can also occur at any time. Such avalanche prone locations for gliding avalanches are to be found in particular on very steep grassy slopes. Areas with glide cracks are to be avoided as far as possible.
Wherever the outgoing longwave radiation during the night is reduced the danger will increase more quickly. Backcountry tours should be started very early and concluded timely.

Outgoing longwave radiation during the night will be quite good. The weather will be very mild. The surface of the snowpack will freeze to form a strong crust only at high altitudes and will already soften in the late morning. The spring-like weather conditions as the day progresses will give rise to increasing and thorough wetting of the snowpack.

Wet snow represents the main danger. Wet loose snow avalanches are possible. Fresh wind slabs in the high Alpine regions.
The conditions are unfavourable for backcountry touring. During the course of the night as a consequence of the rain there will be an increase in the danger of wet avalanches. This applies in particular below approximately 2800 m. The avalanche danger in particular in the regions exposed to heavier precipitation is within the uppermost range of danger level 2 (moderate). Especially on very steep west, north and east facing slopes and below approximately 2600 m medium-sized and, in isolated cases, large wet avalanches are to be expected as the penetration by moisture increases. In isolated cases, the avalanches can reach areas without any snow cover in steep gullies.
Fresh wind slabs can be released by a single winter sport participant in some cases in particular on very steep shady slopes above approximately 2800 m. Such avalanche prone locations are to be found adjacent to ridgelines and in gullies and bowls.

The rain will give rise to increasing and thorough wetting of the snowpack at high altitude. This situation will give rise to a loss of strength within the snowpack especially on west, north and east facing slopes.
Above approximately 2600 m: 10 to 20 cm of snow, and even more in some localities, fell today. 5 to 15 cm of snow, and even more in some localities, will fall on Wednesday. As a consequence of new snow and a sometimes strong southerly wind, rather small wind slabs will form. These are lying on soft layers on very steep shady slopes.
Tendency
Slight decrease in danger of wet avalanches as a consequence of the ceasing of precipitation. The surface of the snowpack will cool hardly at all during the overcast night will already be soft in the early morning. Wet snow represents the main danger.

As a consequence of the precipitation individual wet avalanches are possible, but they will be mostly small.
Snowpack
Outgoing longwave radiation during the night will be severely restricted. The surface of the snowpack will freeze very little and will already be soft in the early morning. The rain will give rise to increasing and thorough wetting of the snowpack. Only a little snow is now lying.
