The fresh snow as well as the wind slabs that are being formed by the storm force to violent southerly wind can be released easily or naturally in all aspects above the tree line. Occasionally large avalanches are possible. At intermediate altitudes these can release the wet old snow as well. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. The peak of avalanche activity will be reached by the early morning probably. Evening: As the wind changes direction, the likelihood of natural dry avalanches being released will increase a little in particular at elevated altitudes. On steep grassy slopes medium-sized and, in isolated cases, large gliding avalanches are possible. This applies especially on steep sunny slopes below approximately 2600 m, including on steep shady slopes below approximately 2200 m. Areas with glide cracks are to be avoided. As a consequence of the rain moist and wet avalanches are possible, even medium-sized ones. This applies in particular on very steep slopes in all aspects below the tree line.
15 to 30 cm of snow, and even more in some localities, will fall. This applies in particular above the tree line. Fresh and somewhat older wind slabs are lying on soft layers in all aspects at elevated altitudes. The rain will give rise to a loss of strength within the snowpack.
Slight decrease in danger of dry avalanches. High altitudes and the high Alpine regions: Fresh wind slabs represent the main danger. Below approximately 2600 m: Wet and gliding snow require caution. As a consequence of warming during the day and solar radiation a large number of wet loose snow avalanches are to be expected as the day progresses, in particular medium-sized ones.
