Individual avalanche prone locations are to be found above approximately 2400 m.

The wind slabs of recent weeks are lying on weak layers especially on east to north to northwest facing aspects above approximately 2400 m. Skiers can release avalanches only in isolated cases, with a large load in most cases, in particular in gullies and bowls, and behind abrupt changes in the terrain on very steep slopes. The avalanches can be triggered in the faceted old snow and reach medium size in isolated cases. In addition as the day progresses in particular on south, southeast and southwest facing slopes, further individual mostly small moist and wet avalanches are possible. This applies in particular in case of releases originating from extremely steep starting zones at intermediate and high altitudes that have retained the snow thus far.

Weak layers exist in the old snowpack on shady slopes. The snowpack is unfavourably layered and has a loosely bonded surface. Sunshine and high temperatures gave rise to increasing moistening of the snowpack on very steep sunny slopes below approximately 3000 m. These conditions will foster a gradual strengthening of the snowpack especially on very steep sunny slopes. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. As a consequence of highly fluctuating temperatures and rain up to approximately 2300 m a crust formed on the surface. The numerous rocks hidden by the recent snow are the main danger.

Until Monday the weather will be mild. The conditions are generally favourable.
