Gliding avalanches and moist snow slides are possible. Fresh wind slabs at high altitude.
Moist loose snow avalanches are possible below approximately 2200 m. In the event of prolonged bright spells this applies on extremely steep slopes. Mostly the avalanches are small and can be released by a single winter sport participant. As a consequence of the moist air there will be an increase in the danger of gliding avalanches. Caution is to be exercised in particular on steep grassy slopes.
As a consequence of a sometimes strong wind from southerly directions, avalanche prone wind slabs formed. Caution is to be exercised in particular on very steep shady slopes adjacent to ridgelines 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 extremely steep shady slopes above approximately 2400 m. Avalanches can reach medium size in isolated cases.
Snowpack
dp.10: springtime scenario dp.6: cold, loose snow and wind
Up to 10 cm of snow, and even more in some localities, has fallen. This applies at high altitudes and in high Alpine regions. The wind will transport the new snow and, in some cases, old snow as well. The fresh wind slabs are lying on soft layers on shady slopes at elevated altitudes. Outgoing longwave radiation during the night will be barely evident. The surface of the snowpack will soften during the day. This applies on very steep sunny slopes, as well as on shady slopes at low and intermediate altitudes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Only a small amount of snow is lying for the time of year.
Tendency
In some localities up to 10 cm of snow will fall. The sometimes strong wind will transport the new snow.

As a consequence of the moist air more frequent moist loose snow avalanches are possible below approximately 2200 m. Mostly these are small and can be released by a single winter sport participant. As a consequence of the moist air there will be an increase in the danger of gliding avalanches. This applies in particular in the west.

Wet snow
New snow and wind slabs represent the main danger. Individual mostly small moist and wet avalanches are possible.
The wind slabs must be evaluated with care and prudence in all aspects above the tree line. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. As a consequence of warming during the day individual small to medium-sized moist and wet avalanches are possible. Wind-loaded slopes where weaknesses exist in the old snowpack are unfavourable. These avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m. Avalanches can reach medium size.
Snowpack

Over a wide area up to 20 cm of snow has fallen above approximately 1700 m. The wind has transported the new snow. The more recent wind slabs are lying on soft layers on shady slopes at elevated altitudes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Only a small amount of snow is lying for the time of year.

The avalanche danger will persist.
