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. With the southerly foehn, small pillows of wind drifted snow formed on shady slopes, which are temporarily still prone to triggering.

Overnight snowfall is unproductive. Due to the many clouds, the snow surface can hardly outgoing longwave radiation overnight and no stable melt-freeze crust forms. In shady high areas, you can still find soft, faceted snow in some places, which has been partly covered by fresh wind slab and now some new fallen snow. 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 and Sunday will be very cloudy and it will continue to snow unproductively until midday. As Sunday progresses, the precipitation will decrease, but the clouds will remain dense. The wind will ease and blow weakly to moderately from south to west.

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