Moderate avalanche danger due to older wind slab!
The avalanche risk is classified as moderate at high altitudes, in some cases even above the tree line. Attention should be paid to snowdrift accumulations from recent snowfall, which can be triggered as medium-sized slab avalanches in steep terrain, sometimes even with a small additional load. There are avalanche prone locations particularly in areas adjacent to the ridgeline and in filled bowls and gullies. Spontaneous loose snow or wet snow avalanches are possible from steep, undischarged slopes at low and sometimes medium altitudes where there is a sufficiently thick snow cover, snowpack.
The mild temperatures have already allowed the snow cover, snowpack to settle. Nevertheless, there are still prone to triggering snow packs at high altitudes, which can contain weak layers or do not always bond sufficiently with the old snowpack. Crystals that have been transformed to build up weaken the snow base, fundament. The snow cover, snowpack in the low and partly medium altitudes varies in moisture and sometimes even wetness depending on altitude and aspect.
On Wednesday, visibility will initially be variable. The sun will often shine during the daytime changes. Little wind. At 1500 m around 5 degrees, at 2000 m around 3 degrees. On Thursday there will be clouds and at least some sunshine. There will be little wind for the most part. At 1500 m it will be around 4 degrees at noon, at 2000 m around 1 degree.
The snow cover, snowpack can continue to settle. Pay attention to avalanche prone locations in steep terrain at high altitudes due to older wind slab.
