Fresh wind slab

Fresh 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, area adjacent to the ridgeline and distant from ridgelines behind terrain edges in the extended northern sector. Fresh, prone-to-triggering wind slabs can also accumulate in gullies and bowls. 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 fresh 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 is made up 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.

It snows in the night to Friday. Around 10 cm will fall along the northern Alps. It will become milder and the snowfall level will rise to around 1400 metres on the northern edge of the Alps. The wind will be moderate to brisk, mainly from the south. On Friday it will snow (5 cm to 10 cm) from dense clouds. The southerly winds will gradually weaken and temperatures will also drop slightly during the daytime changes. At 2000 m -2 to -6 degrees.

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