The avalanche risk is moderate above around 2000 metres and low below. With the southerly foehn, fresh, prone-to-triggering pillows of wind drifted snow develop, which can easily be triggered by individuals in a few places, especially in the extended northern exposures. In addition, in the aspects from west to north to east, medium and occasionally large, dry slab avalanches can still be triggered by individuals in a few places. Danger areas are difficult to recognise away from freshly formed drift snow packs. Take particular care at the transitions from little to more snow. The likelihood of gliding avalanches remains somewhat increased.

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 partly transported in the foehn aisles and partly overlaid by fresh wind slab in windless areas. 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.

Away from the immediate main Alpine ridge, the night begins with clear skies, but in the second half of the night there will be increasing cloud cover from the west. Foehn-like mountain weather then sets in on Saturday. High cloud fields move over the peaks, occasionally shading out the sunshine. Along the Hohe Tauern and Lungauer Nockberge, low clouds will also accumulate from the south and restrict visibility. The southerly wind will blow strongly in the high areas of the Tauern, with gusts of up to 80 km/h, and further north with gusts of around 60 km/h. Towards the evening, unproductive precipitation will set in. Temperatures at 2000 m from south to north between -3 and +2 degrees, at 3000 m between -7 and -4 degrees.

The southerly foehn subsides and it snows unproductively. The avalanche danger does not change significantly.
