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. Occasionally, fresh, small-scale pillows of wind drifted snow develop that are temporarily prone to triggering.

During the partly cloudy night, only a thin melt-freeze crust forms, which softens again during the day. In shady high altitudes, soft, faceted snow can often still be found on the surface, which can be transported in particularly susceptible foehn lines. Below this lies a well-set sequence of compact, older 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.

The night begins mostly starry, with more clouds gathering from the south in Lungau. In the second half of the night, more clouds will generally gather from the west. On Saturday, high cloud fields will pass through, shading out the sunshine at times. The southerly wind will blow in Lungau with gusts of up to 50 km/h, in the north it will be much weaker. Towards the evening, unproductive precipitation will set in. Temperatures at 2000 m between -2 and +1 degrees, at 3000 m around -7 degrees.

The southerly wind is easing and it's not snowing heavily. The avalanche risk does not change significantly.
