        "comment": "During the course of the day, danger of wet-snow avalanches will increase. Isolated wet slab avalanches can be triggered by winter sports enthusiasts. After the melt-freeze crust (capable of bearing loads) softens up, also naturally triggered wet-snow avalanches are possible. Caution urged particularly towards steep shady slopes at 2200-2500m which have not yet discharged and slopes in all aspects where there is area-wide snow on the ground. Avalanches can fracture in weak old snowpack layers, in isolated cases grow to large size and lay back huge runout zones, quite atypically. On steep slopes with lots of snow on the ground which have not yet discharged with smooth underground, such as grass-covered slopes or rock plates, glide-snow avalanches can release in all aspects. In addition, winter sports enthusiasts can trigger isolated avalanches in near-surface weak layers on high-altitude shady slopes. Such danger zones are nearly impossible to recognize.",
