Wet snow represents the main danger. Fresh wind slabs in the high Alpine regions.
Wet avalanches can as before be released by a single winter sport participant. The avalanche prone locations are to be found especially on very steep west, north and east facing slopes below approximately 2800 m. Avalanches can release the saturated snowpack and reach medium size. As a consequence of warming during the day there will be only a slight increase in the danger of wet avalanches. Individual gliding avalanches can also occur, caution is to be exercised in particular on very steep grassy slopes in the regions with a lot of snow.
The wind slabs can be released by a single winter sport participant in isolated cases in particular on very steep shady slopes in high Alpine regions. Such avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain.
Snowpack
dp.10: springtime scenario dp.6: cold, loose snow and wind
The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. The snowpack will be wet all the way through. This applies on shady slopes below approximately 2600 m, as well as on sunny slopes below approximately 3000 m. Sunshine and high temperatures will give rise as the day progresses to increasing softening of the snowpack below approximately 2800 m. On steep sunny slopes as well as at low and intermediate altitudes only a little snow is now lying.
High Alpine regions: As a consequence of a strong wind from southeasterly directions, wind slabs formed. These are lying on soft layers on steep shady slopes. The weather effects will foster a rapid strengthening of the snow drift accumulations.
Tendency
The surface of the snowpack will freeze to form a strong crust and will soften during the day. Wet snow requires caution.

New snow and wet snow represent the main danger. The new snow and wind slabs of the last few days must be evaluated with care and prudence above approximately 2400 m.
The conditions are sometimes unfavourable for backcountry touring outside marked and open pistes. The more recent wind slabs are lying on the unfavourable surface of an old snowpack in particular on very steep west, north and east facing slopes above approximately 2400 m. Such avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls. In particular on very steep slopes and below approximately 2600 m numerous medium-sized and, in isolated cases, large moist and wet avalanches are possible as the moisture increases. In particular on very steep west, north and east facing slopes medium-sized to large moist and wet avalanches are to be expected. In isolated cases, the avalanches can reach areas without any snow cover in steep gullies.
Snowpack
dp.10: springtime scenario
The rain gave rise to increasing and thorough wetting of the snowpack below approximately 2200 m. This situation will give rise to a loss of strength within the snowpack in particular on steep slopes. In some regions 40 to 100 cm of snow, and even more in some localities, has fallen above approximately 2400 m.
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. The new snow and wind slabs must be evaluated with care and prudence in high Alpine regions.

Wet snow represents the main danger.
As the penetration by moisture increases individual wet avalanches are possible, but they will be mostly small. At the base of rock walls and behind abrupt changes in the terrain and adjacent to ridgelines and in gullies and bowls medium-sized and, in isolated cases, large wet loose snow avalanches are possible above approximately 1800 m.

A lot of rain has fallen. The rain gave rise to increasing moistening of the snowpack. The snowpack will be wet all the way through over a wide area. Below approximately 1800 m a little snow is lying.

Wet snow requires caution.

Increase in danger of wet avalanches.
From the early morning as the penetration by moisture increases there will be an increase in the danger of wet avalanches. Wet avalanches can in some places be released by a single winter sport participant. The avalanche prone locations are to be found especially on very steep west, north and east facing slopes below approximately 2800 m. Avalanches can release the saturated snowpack and reach medium size.
Individual gliding avalanches can also occur, caution is to be exercised in particular on very steep grassy slopes in the regions with a lot of snow.
Snowpack
dp.10: springtime scenario
The surface of the snowpack will only just freeze and will already soften in the late morning. Some rain will fall from the afternoon in some localities, especially in the north.
The weather effects facilitated a substantial strengthening of the snow drift accumulations.
Tendency
During the night the weather will be clear at times, especially in the north. The surface of the snowpack will soften during the day. In the regions where the outgoing longwave radiation during the night is reduced the danger will increase more quickly.
Danger level
Low avalanche danger will prevail.
Only isolated wet avalanches are possible.
Snowpack
Outgoing longwave radiation during the night will be severely restricted. The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. The snowpack will be wet all the way through. Only a little snow is now lying.
