As a consequence of new snow and a moderate to strong southerly wind, avalanche prone wind slabs formed on Tuesday in the regions exposed to heavier precipitation. These are lying on weak layers in particular on shady slopes. The avalanches can be triggered in the faceted old snow. Sometimes they are medium-sized and can be released in some cases even by a single winter sport participant, in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example on very steep slopes. Some small and, in isolated cases, medium-sized dry snow slides and avalanches are possible as a consequence of the new snow. This applies in particular on extremely steep slopes at intermediate and high altitudes.
10 to 20 cm of snow, but less in some localities, fell on Tuesday above approximately 1600 m. Weak layers exist in the old snowpack on shady slopes. The snowpack is unfavourably layered. The new snow and wind slabs of Tuesday are lying on the unfavourable surface of an old snowpack in particular on shady slopes at intermediate and high altitudes. This snow is bonding only slowly with the old snowpack. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. As a consequence of rising temperatures and solar radiation a crust formed on the surface at the weekend. At low and intermediate altitudes only a little snow is now lying. The numerous rocks hidden by the recent snow are the main danger.
On Thursday it will be mostly sunny.
