The danger of moist and wet avalanches will already exist in the early morning. This applies in all aspects at low and intermediate altitudes. High altitudes: As the day progresses the likelihood of dry and wet avalanches being released will increase. In the event of prolonged bright spells this applies in particular. Avalanches can in particular be released in near-surface layers and reach medium size. As a consequence of warming during the day and solar radiation individual natural avalanches are possible. Avalanche prone locations are to be found in particular on very steep west, north and east facing slopes between approximately 2200 and 2800 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. Avalanches can in isolated cases penetrate near-ground layers of the snowpack and reach large size.
Outgoing longwave radiation during the night was reduced. The surface of the snowpack will already soften in the late morning. Isolated avalanche prone weak layers exist in the top section of the old snowpack, especially on west, north and northeast facing slopes between approximately 2200 and 2800 m, and on sunny slopes in high Alpine regions. Towards its base, the snowpack consists of faceted crystals, in particular on west, north and east facing slopes at elevated altitudes.
Outgoing longwave radiation during the night will be good over a wide area. The avalanche danger will increase a little during the day.
