Low avalanche danger. Isolated danger zones due to fresh drifts.
The higher temperatures will stabilise the snowpack fundament and the older drifts, thereby diminishing the avalanche dangber. Depending on the amount of fresh snow and wind, a new snowdrift problem could be generated on Friday at high altitudes.
Thursday will start with sunshine, milder tempertures, only a bit of cirrus cloud. At 2000 m: 0 to -2 degrees. Winds will be light to moderate from S to SW. In the afternoon, clouds will move in from the west. On Thursday night, temperatures will drop slightly, in the southern and eastern massifs, snowfall will set in.
Low avalanche danger. Isolated danger zones due to fresh drifts.
Avalanche danger in the borderline ranges is low, but isolated avalanche prone locations exist where small slab avalanches can be triggered. The danger zones: freshly generated snowdrift locations near ridgelines, behind discontinuties in the terrain, at the entries into gullies and bowls and at forest edges. Nevertheless, the releases will be small-sized.
The snowpack fundament in the borderline mountain ranges is melt-freeze encrusted for the most part, but also riddled with weak intermediate layers and surface hoar. Atop the surface hoar there is now 20-30 cm of loose, fresh snow which has frequently been transported to gullies and bowls and edges of forests. In many places there is still powder. Exposed zones are utterly windblown.
