Border Graie Alps

In very isolated cases weak layers exist in the snowpack on very steep shady slopes.

In very isolated cases weak layers exist in the snowpack on very steep shady slopes.

A clear night will be followed in the early morning by favourable conditions. 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 large size in isolated cases. Especially very steep sunny slopes as well as places that are protected from the wind: As a consequence of warming during the day and solar radiation more small and medium-sized dry and moist avalanches are possible below approximately 2600 m.

Outgoing longwave radiation during the night was quite good. The surface of the snowpack has frozen to form a strong crust and will soften later than the day before. The weather conditions facilitated a substantial stabilisation of the near-surface layers. Towards its surface, the snowpack is dry; its surface consists of loosely bonded snow. After a clear night this applies in particular above approximately 2200 m.

Until Monday the weather will be very warm. As the day progresses as a consequence of warming during the day and solar radiation there will be a gradual increase in the danger of moist and wet avalanches.
