Border Graie Alps

As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the avalanche danger.

As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the avalanche danger.

A clear night will be followed in the early morning by favourable conditions. Especially very steep sunny slopes as well as base of rock walls: As a consequence of warming during the day and solar radiation medium-sized and, in isolated cases, large moist and wet avalanches are possible below approximately 2700 m. Isolated avalanche prone weak layers exist in the old snowpack on little used northwest, north and northeast facing slopes. These can as before be released by large loads and reach medium size.

Outgoing longwave radiation during the night was quite good. As a consequence of falling temperatures a crust formed on the surface during the course of the night. Towards its surface, the snowpack is dry; its surface consists of loosely bonded snow. After a clear night this applies in particular above approximately 2500 m. Sunshine and high temperatures will give rise from early morning to increasing moistening of the snowpack in particular on sunny slopes below approximately 2700 m.
