As a consequence of the rain, the likelihood of wet avalanches being released will increase.
As a consequence of the rain, the likelihood of wet avalanches being released will increase in particular below approximately 2200 m, especially on steep west, north and east facing slopes. In these regions natural avalanches are to be expected, even large ones in isolated cases.
In addition the fresh wind slabs in high Alpine regions are capable of being triggered in some cases, in particular on near-ridge slopes. The avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2200 m. Such avalanche prone locations are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable.
Snowpack
dp.3: rain dp.6: cold, loose snow and wind
Below approximately 1800 m only a little snow is lying. At higher altitudes there are 30 to 80 cm of snow, and even as much as 150 cm in some localities. 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 2200 m rain will fall. The rain will give rise to a loss of strength within the snowpack especially on steep shady slopes.
20 to 40 cm of snow, and even more in some localities, will fall above approximately 2200 m. As a consequence of a strong wind, sometimes easily released wind slabs will form in high Alpine regions.
Steep west, north and east facing slopes above approximately 2400 m: Large-grained weak layers exist in the bottom section of the old snowpack.
Tendency
Slight decrease in danger of wet avalanches as the snowfall level drops.

As a consequence of the rain, the likelihood of wet avalanches being released will increase in particular on steep shady slopes below approximately 2200 m. In these regions natural avalanches are to be expected, even large ones.
Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2400 m. Such avalanche prone locations are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable. 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.

Below approximately 1800 m only a little snow is lying. At higher altitudes there are 30 to 80 cm of snow, and even as much as 150 cm in some localities. The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. The sleet will give rise to a loss of strength within the snowpack in some places below approximately 2200 m.
Steep west, north and east facing slopes above approximately 2200 m: Faceted weak layers exist in the bottom section of the old snowpack. Above approximately 2200 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 natural wet avalanches are to be expected.
The danger of moist and wet avalanches will already be elevated in the early morning. As a consequence of the rain, the likelihood of wet avalanches being released will increase in particular on steep shady slopes. Individual natural avalanches are to be expected, even medium-sized ones.
Snowpack
dp.10: springtime scenario 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 2200 m and above rain will fall. The weather conditions towards the evening will give rise to increasing and thorough wetting of the snowpack. This situation will give rise to a loss of strength within the snowpack especially on steep shady slopes.
Tendency
Slight decrease in danger of wet avalanches as the snowfall level drops. Above approximately 2000 m snow will fall in some regions.
