Graie Alps

The danger of wet and gliding avalanches will already increase in the late morning.

The danger of wet and gliding avalanches will already increase in the late morning.

The early morning will see favourable conditions generally, but the danger of wet and gliding avalanches will increase later. The weather will be warm. The weather conditions will cause a rapid weakening of the snowpack from midday in particular on very steep northeast, southeast and west facing slopes. In the last few days the natural activity of small and medium wet and gliding avalanches has only slowly increased. As the temperature drops there will be only a slight decrease in the danger of wet and gliding avalanches. In particular at the base of rock walls and on extremely steep east, southeast and west facing slopes more medium-sized moist and wet avalanches are possible as a consequence of warming during the day and solar radiation. This also applies on very steep shady slopes also above approximately 2300 m. , when first humidification reaches the persistent layers within the snowpack. Backcountry tours and off-piste skiing should be started and concluded very early.

Outgoing longwave radiation during the night was good. The surface of the snowpack will freeze to form a strong crust and will soften quickly, especially on east, southeast and west facing slopes, as well as at low and intermediate altitudes. The spring-like weather conditions gave rise to gradual consolidation of the snowpack. These conditions facilitated a substantial favourable transformation of the snowpack in particular on sunny slopes. All aspects low and intermediate altitudes: The snowpack is moist and its surface has a melt-freeze crust. Especially steep shady slopes high altitudes: The snowpack is dry and its surface has a strong crust.

As the temperature drops there will be only a slight decrease in the danger of wet and gliding avalanches.
