The avalanche risk is moderate above around 2000 metres and low below that. 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. Such avalanche prone locations are rare but often unrecognisable. Take particular care at the transitions from little to more snow. In addition, the southerly foehn has created pillows of wind drifted snow that can still be easily triggered by individuals, especially in the extended northern exposures. Danger areas are usually adjacent to ridgelines and behind terrain edges. In sunny conditions, small loose snow avalanches can be triggered from extremely steep sunny slopes.
Overnight snowfall is unproductive. Due to the many clouds, the snowpack can hardly outgoing longwave radiation overnight and no melt-freeze crust forms. In shady high altitudes, you can still find soft, faceted snow on the surface 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 cloudy and it will snow widely but not heavily until midday. Most of the snow will fall in Oberpinzgau on the borders with Tyrol and Carinthia and even here it will only be a maximum of 10 cm. The precipitation will continue to decrease over the course of Sunday, but the clouds will remain dense. The southerly foehn will ease during the night and the wind will only blow moderately to briskly from south to west in the summit regions.
With a brisk westerly wind, it will snow unproductively on Monday, the avalanche danger will not change significantly.
