Rare danger zones in transitions where the snow is shallow
The situation is unchanged: avalanche danger is LOW. Only in very few places can large addtional loading trigger a slab avalanche, most likely in transitions where snow is shallow, into deeper snow, in shady and extremely steep terrain. Then, avalanches can grow to medium size. Most avalanche prone locations occur in W/N/E aspects distant from ridgelines and in steep gullies. In high alpine regions (above 2600m) these rare avalanche prone locations (shallow-snow transitions in very steep terrain) cannot be ruled out on south facing slopes as well.
On shady slopes there is old powder atop a compact old snowpack. On sunny slopes there is a bit of firn snow, the uppermost centimetres are becoming sticky. Hidden inside the old snow are soft layers of expansively metamorphosed (faceted) crystals, but are unlikely to trigger except in isolated cases.
Nights of clear skies. Sunshine during the daytime. On Wednesday, sunny and excellent visibility. The northerly winds will reach 40 km/hr. At 2000 m at midday: -4 degrees, at 3000 m: -11 degrees. On Thursday, sunny, outstanding visibility, little wind. At 2000 m: -3 degrees; at 3000 m: -7 degrees.
No significant change is expected. The steep south-facing slopes will be moistened for a few hours.
