A dangerous avalanche situation will prevail. Wet snow represents the main danger.
As a consequence of the rain, the likelihood of wet avalanches being released will increase in particular below approximately 2500 m, especially on steep west, north and east facing slopes. In these regions natural avalanches are to be expected, even large ones.
Dry and wet avalanches can additionally in some places be released, even by a single winter sport participant. This applies on steep west, north and east facing slopes above approximately 2500 m. Avalanches can be triggered in deep layers and reach large size.
In addition the fresh wind slabs in high Alpine regions are capable of being triggered in some cases, in particular on near-ridge shady slopes.
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.
10 to 20 cm of snow, and even more in some localities, will fall above approximately 2500 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 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.
Tendency
Decrease in danger of wet avalanches as the snowfall level drops. Above approximately 2000 m snow will fall in some regions.
