South foehn and north-westerly winds formed prone to triggering wind slab.

The avalanche danger is moderate above 2000 metres and low below. Small (occasionally medium) snow slabs can be triggered by individual winter sports enthusiasts in some places, adjacent to the ridgeline and distant from ridgelines behind terrain edges in the north-west, over east to south-facing terrain. Wind slabs have also accumulated in gullies and bowls. Some of the windslab snow will be covered with snow during the daytime changes, making it difficult to recognise. In addition to the risk of burial, attention must be paid to the risk of being swept away and falling. There are also still many rocks lurking.

Wind and snowfall form(ed) wind slabs. The weak layer for a snow slab can be the last snow to fall, surface hoar as well as faceted crystals above/below the uppermost crust. The old snowpack consists of layers of faceted crystals, deep rime and melt-freeze crusts and has little tendency to break up. The amount of snow is well below average.

During the night to Friday it will snow about 5 cm. The wind will be moderate to brisk, mainly from the south. On Friday it will snow from dense clouds. Most of the new fallen snow (about 10 cm) will fall in the morning. The southerly wind will gradually weaken. Visibility will improve somewhat in the afternoon and the snowfall will subside. Hardly any wind. At 2000 m -3 to -8 degrees, at 3000 m -9 to -14 degrees.

Wind and new fallen snow will form fresh wind slabs at the weekend. The avalanche risk increases slightly.
