Wet-snow avalanches during the course of the day
Due to daytime warming and solar radiation, wet loose-snow avalanches can be expected in steep terrain. Wherever there is lots of snow on the ground, these releases can grow to large size. On steep grass-covered slopes, glide-snow avalanches can occur. Zones with glide cracks on the surface should under all circumstances be avoided. Particularly on very steep shady slopes above 1800m, avalanches can fracture down to deeper-down layers inside the snowpack in isolated cases.
Wherever there is still snow on the ground, it is thoroughly moist-to-wet and forms a melt-freeze crust during the nocturnal hours. Only above 1800m on shady slopes are there still weak layers in places in the lower most part of the snowpack.
High-pressure weather conditions will persist, continuing sunshine, mild temperatures. Temperature at 2000m: +6 degrees, at 3000m 0 degrees. Light to moderate southwesterly winds at high altitudes.
As a result of high-pressure weather conditions, the daytime rise in avalanche danger persists.
