The danger of wet avalanches will already increase in the late morning. Weak layers in the old snowpack can still be released in isolated cases.

The danger of wet avalanches will already increase in the late morning. Weak layers in the old snowpack can still be released in isolated cases.

In the late morning as a consequence of warming during the day and solar radiation there will be a rapid increase in the danger of moist and wet avalanches. Avalanches can penetrate deep layers and reach medium size. This applies in all aspects in particular below approximately 2600 m, also on very steep sunny slopes at elevated altitudes. Avalanche prone locations for dry avalanches are to be found in particular on very steep west, north and east facing slopes above approximately 2400 m. The avalanche prone locations are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable. In steep terrain there is a danger of falling on the hard snow surface.

Outgoing longwave radiation during the night will be good. The surface of the snowpack has frozen to form a strong crust only at high altitudes and will already soften in the late morning. Sunshine and high temperatures will give rise to increasing and thorough wetting of the snowpack. This applies in all aspects below approximately 2600 m, as well as on steep sunny slopes at elevated altitudes. The old wind slabs are lying on top of a weakly bonded old snowpack in particular on west, north and east facing slopes above approximately 2400 m. The snowpack will be subject to considerable local variations. On steep sunny slopes at low and intermediate altitudes hardly any snow is lying.

Outgoing longwave radiation during the night will be good over a wide area. The avalanche danger will increase during the day.
