The danger of moist and wet avalanches will already be elevated in the early morning. Weak layers in the old snowpack can be released in some places by individual winter sport participants.

The danger of moist and wet avalanches will already be elevated in the early morning. Avalanches can penetrate deep layers and reach large size in isolated cases. This applies in all aspects in particular below approximately 2400 m. Avalanches can additionally in some places be released in the weakly bonded old snow easily. Such avalanche prone locations are to be found in particular on very steep west and east facing slopes between approximately 2400 and 2800 m and on very steep shady slopes above approximately 2400 m. The avalanche prone locations are difficult to recognise. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. 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. In steep terrain there is a danger of falling on the hard snow surface. This applies on extremely steep sunny slopes at elevated altitudes.

Outgoing longwave radiation during the night will be reduced. The surface of the snowpack will freeze very little. Some rain will fall. The snowpack will become increasingly wet all the way through. This applies in all aspects below approximately 2400 m. 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 altitude, as well as on steep sunny slopes in high Alpine regions.

Increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.
