Wet snow represents the main danger. As a consequence of the rain natural wet avalanches are to be expected.
As a consequence of the rain, the likelihood of wet avalanches being released will increase in particular on steep shady slopes below approximately 2500 m. In these regions natural avalanches are to be expected, even large ones. Moist and wet avalanches can additionally in some places be released, even by a single winter sport participant, this also applies on steep west, north and east facing slopes below approximately 2800 m.
Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m. In addition the fresh wind slabs in high Alpine regions are capable of being triggered in isolated cases, in particular on near-ridge shady slopes. Wind slabs are mostly small.
Snowpack
dp.3: rain dp.1: deep persistent weak layer
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 2500 m rain will fall. The rain will give rise to a loss of strength within the snowpack especially on steep shady slopes.
Steep west, north and east facing slopes above approximately 2500 m: Isolated avalanche prone weak layers exist in the top section of the old snowpack. Faceted weak layers exist in the bottom section of the old snowpack.
Above approximately 2500 m snow will fall. As a consequence of a strong wind, small wind slabs will form in high Alpine regions.
Tendency
Slight decrease in danger of wet avalanches as the snowfall level drops. Above approximately 2000 m snow will fall in some regions.

Wet snow represents the main danger. As a consequence of the rain wet avalanches are to be expected at any time.
The danger of moist and wet avalanches will already be elevated in the early morning. This applies on very steep sunny slopes in particular below approximately 2800 m, as well as in all aspects below approximately 2500 m. As a consequence of the rain, the likelihood of avalanches being released will increase especially on steep shady slopes below approximately 2500 m. Avalanches can in isolated cases penetrate near-ground layers of the snowpack and reach medium size.
Individual avalanche prone locations for dry avalanches are to be found in particular on very steep west, north and east facing slopes above approximately 2500 m. These places are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable. Avalanches can reach medium size.
In addition the fresh wind slabs in high Alpine regions are prone to triggering in some cases, especially adjacent to ridgelines. These are mostly small.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
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 soften quickly. This applies on very steep sunny slopes in particular below approximately 2800 m, as well as in all aspects below approximately 2500 m.
Some rain will fall. These weather conditions will give rise to increasing and thorough wetting of the snowpack.
Isolated avalanche prone weak layers exist in the top section of the old snowpack. Towards its base, the snowpack consists of faceted crystals. This applies in particular on west, north and east facing slopes at high altitudes and in high Alpine regions.
Tendency
The danger of wet avalanches will persist.

As a consequence of the rain, the likelihood of wet avalanches being released will increase. This applies in all aspects. Avalanches are rather small but easily released. Avalanches can in isolated cases release deeper layers of the snowpack and reach medium size.
