The avalanche risk is low. Medium-sized slab avalanches can still be triggered in a few hard-to-recognise places, especially in the extended northern sector above 1800 m, but usually only with a large additional load. This is in particular at the transitions from little to more snow.

On the sunny slopes, isolated wet snow avalanches are possible as the snowpack softens. These usually remain small.

Only a few centimetres of new fallen snow fell, below around 1700 m it rained lightly. In shady high altitudes, soft, faceted snow can often still be found on the surface. In most cases, however, the surface is at least just crust can form. Below this lies a well-set sequence of compact drift snow layers, in which a crust is embedded in combination with faceted crystals. The connection at the transition to the old snow foundation, which consists mainly of deep rime, is still poor. Deep and sunny middle layers are largely snowed out.

It will clear up increasingly during the night. Friday will bring sunny and stable mountain weather. High fog may persist in some valleys at first, especially in Lungau. During the daytime changes, a few low clouds from the south may occasionally restrict visibility. The wind will mostly be light. Temperatures will rise to 0 to 3 degrees at 2000 metres.

No significant change in avalanche danger despite strong foehn on Saturday.
