The danger of moist and wet avalanches will already exist in the early morning.

The danger of moist and wet avalanches will already exist in the early morning.

The danger of moist and wet avalanches will already exist in the early morning. As the day progresses as a consequence of warming during the day and solar radiation there will be an additional increase in the danger. This applies in all aspects below approximately 2400 m, as well as on very steep sunny slopes below approximately 3000 m. Avalanches can in isolated cases penetrate near-ground layers of the snowpack and reach medium size. Individual 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. These places are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable. Avalanches can reach medium size. 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.

Outgoing longwave radiation during the night will be reduced. The surface of the snowpack will only just freeze and will soften quickly. The snowpack will become increasingly wet all the way through. This applies in all aspects below approximately 2400 m, and on sunny slopes at elevated altitudes. 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 altitudes and in high Alpine regions.

As a consequence of mild temperatures very cloudy skies the snowpack can not consolidate during the night. Some rain will fall on Monday. As a consequence of the rain, the likelihood of wet avalanches being released will increase in particular on steep shady slopes below approximately 2500 m.
