Over a wide area stormy weather and new snow: The danger of dry and moist avalanches will increase significantly during the day.
Over a wide area stormy weather and new snow: The danger of dry and moist avalanches will increase significantly during the day.
Over a wide area 40 to 70 cm of snow, and even more in some localities, will fall on Thursday above approximately 2500 m. As a consequence of new snow and a strong to storm force wind from westerly directions, deep wind slabs will form from the middle of the day in the regions exposed to heavier precipitation as well as above approximately 2500 m. The fresh snow and the wind slabs are lying on top of a weakly bonded old snowpack in particular on steep shady slopes. In particular from starting zones at higher altitudes many medium-sized and large loose snow avalanches are to be expected as the precipitation becomes more intense. Dry slab avalanches and ground avalanches are to be expected from the evening. The avalanches can occur easily or triggered naturally. The new snow and wind slabs can be released easily, even by a single winter sport participant, in all aspects above approximately 2500 m. As the snowfall level rises numerous moist and wet avalanches are possible, even quite large ones. In the event of rain this applies in particular below approximately 2500 m and.
Less snow than usual is lying. On sunny slopes below approximately 2300 m from a snow sport perspective, insufficient snow is lying. Faceted weak layers exist in the old snowpack especially on steep shady slopes. In the last few days hardly any more avalanches were reported.
Stormy weather and new snow above approximately 2500 m: The avalanche danger will increase but remain within the current danger level.
