On Tuesday the wind slabs have increased in size moderately. These are lying on weak layers in particular on very steep shady slopes. The fresh wind slabs can be released, even by small loads in isolated cases. They must be evaluated with care and prudence. The avalanche prone locations for dry avalanches are to be found in areas where the snow cover is rather shallow and at transitions into gullies and bowls. The avalanches can be triggered in the faceted old snow and reach medium size.

2 to 10 cm of snow fell on Tuesday above approximately 1200 m. Weak layers exist in the old snowpack on shady slopes. The snowpack is unfavourably layered and has a loosely bonded surface. As a consequence of rising temperatures and solar radiation a crust formed on the surface at the weekend. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. The numerous rocks hidden by the recent snow are the main danger.

On Friday it will be mostly sunny.
