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

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

The danger of moist and wet avalanches will already exist in the early morning. This applies in all aspects below approximately 2400 m. As a consequence of warming during the day and the solar radiation, the likelihood of avalanches being released will increase especially on very steep sunny slopes below approximately 2800 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.
