Low avalanche danger, but isolated avalanche prone locations!
Low avalanche danger, but isolated avalanche prone locations!
The avalanche danger is low. However, older snowdrift accumulations in gullies and bowls and behind broad ridges and ridgelines above the tree line can occasionally be triggered as small slab avalanches.
Snowdrift accumulations often lie on faceted crystals or surface hoar, which can act as a weak layer. However, the warming has a stabilising effect on this weak layer. Windward terrain is usually blown off and almost snow-free.
During the first half of the night, the snowfall level will rise from 900 m to 1400 m, while it will snow a little in the eastern mountain groups or rain at low altitudes. On the Wechsel, dense residual clouds will persist until midday. In the western peripheral mountains, the sky will be largely clear on Tuesday, with only thin, high veil clouds passing by. The temperature at an altitude of 2000 metres will be a mild 0 to +3 degrees. A strong north-westerly wind will blow in the eastern mountain ranges.
Wednesday will be mild and mostly sunny. The avalanche risk remains low.
