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 danger of dry and moist avalanches.

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

Wind slabs can still in isolated cases be released by small loads, but they will be small in most cases. This applies in particular on very steep shady slopes especially above approximately 2400 m. Isolated avalanche prone weak layers exist in the snowpack on little used northwest, north and northeast facing slopes. These can especially at their margins be released by large loads and reach large size in isolated cases. In particular 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 medium-sized and, in isolated cases, large moist and wet avalanches are possible.

The surface of the snowpack will soften earlier than the day before. The weather conditions facilitated a gradual stabilisation of the snow drift accumulations. Sunshine and high temperatures gave rise to moistening of the snowpack in particular on sunny slopes below approximately 2800 m. As a consequence of highly fluctuating temperatures and partly cloudy skies a crust formed on the surface during the last few days, also on shady slopes below approximately 2500 m. The weather will be mild. As a consequence of warming during the day and solar radiation more medium-sized and, in isolated cases, large moist and wet avalanches are possible.

Outgoing longwave radiation during the night will be reduced in some case. The surface of the snowpack will soften earlier than the day before. The danger of moist snow slides and avalanches will already increase in the late morning.
