Wind slabs above approximately 1900 m. Slab avalanches are possible.

The sometimes strong wind has transported some snow. On Thursday the previously small wind slabs have increased in size additionally. As a consequence of a strong wind from westerly directions, wind slabs formed in particular in gullies and bowls and behind abrupt changes in the terrain. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in northwest to north to east facing aspects above approximately 1900 m. The wind slabs must be evaluated with care and prudence.

As a consequence of the strong westerly wind, snow drift accumulations formed. The wind slabs have bonded with the old snowpack. They are to be assessed with care and prudence. The wind slabs are bonding only slowly with the old snowpack. Reports filed by observers and stability tests confirm the favourable bonding of the snowpack.
