Persistent weak layers
- Todas las altitudes
Only adjacent to ridgelines and at higher elevations is some fresh drift snow possible and local persistent weak layer problems!

Due to some new fallen snow and depending on the wind influence around the west, there may be some fresh wind slab, which can be prone to triggering in steep terrain. Avalanche prone locations are mainly adjacent to ridgelines and behind terrain edges. In the north-facing high altitudes, the local persistent weak layer problem must still be taken into account in steep terrain. Slab avalanches can be triggered here in particular by large additional loads.
There was up to 10 cm of new fallen snow with little wind influence. Only in very exposed areas could there be some fresh wind slab. The old snowpack still contains unbound faceted crystals and partly floating snow. The new fallen snow lies on an often hard to partly icy old snow surface. In general, there is only a little snow, which is very unevenly distributed. Before the snowfall, there were many pale and completely blown-off areas.
On Wednesday, a few compact high cloud fields will repeatedly pass above the peaks, but it will remain dry. Intermittent sunny spells are possible and visibility will be quite good except for occasional slightly diffuse light. The wind will be mostly moderate to brisk from east to south at low altitudes, with strong, sometimes stormy southerly winds to be expected in the high alpine regions above the tree line. This will weaken a little in the afternoon. At 1500 metres around 4 degrees, at 2000 metres around 2 degrees. It will start to snow in the night to Thursday. The snowfall level will be around 500 metres. Thursday will start wintry and there will be widespread new fallen snow. From around midday, it will become increasingly dry and it may clear up in places with some sunshine. The wind will be moderate from the west. It will be -4 degrees at 1500 metres and -6 degrees at 2000 metres.
No significant change.
