Moist and wet snow slides are the main danger.

Moist and wet snow slides are the main danger.

In the early morning the natural activity of small and medium moist and wet avalanches will gradually increase, in particular on sunny slopes at elevated altitudes, as well as on very steep shady slopes below approximately 2400 m. As a consequence of the rain, the likelihood of wet avalanches being released will increase in particular on shady slopes below approximately 2400 m. Weak layers in the old snowpack can be released in very isolated cases by winter sport participants.

The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. The spring-like weather conditions gave rise to gradual and thorough wetting of the snowpack, especially on steep sunny slopes at high altitudes and in high Alpine regions, as well as on west, north and east facing slopes at intermediate and high altitudes. These conditions will bring about a weakening of the snowpack. Up to 2400 m rain will fall from the afternoon in some regions. Faceted weak layers exist in the old snowpack.

Outgoing longwave radiation during the night will be reduced in some case. Moist and wet avalanches are the main danger.
