The avalanche risk is considerable from around 2000 m and low below (with a smooth transition). In some places, medium to large slab avalanches can be triggered by individuals, especially in the aspects from north-west to north to east. Danger areas are often difficult to recognise and a defensive choice of route is still advised. Take particular care at the transitions from little to more snow.

On sunny slopes, wet slabs of snow are possible in terrain that has not yet been unloaded as the snowpack softens during daytime changes. In very high to high alpine locations, these can occasionally break through into weak layers close to the ground.

The snowpack can cool down well overnight and form a melt-freeze crust. On sunny slopes, this softens during the day and the snowpack is damp or wet up to high altitudes. In shady high altitudes, some soft, faceted snow can still be found on the surface, some of which has already crusted can form. Below this lies a now well-set and connected sequence of compact drift snow layers, but often a crust with faceted crystals is still embedded in the upper area (the old snowpack before the last major precipitation). 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 will be cloudless for long stretches. Temperatures during the night at 2000 m: -1 to +3 degrees, at 3000 m around -5 degrees. On Sunday, we can expect almost bright sunshine at first. During the day, high cloud fields will gather, which may cloud the sky a little in addition to the Sahara dust. In the afternoon, temperatures will be between +1 and +4 degrees at 2000 metres and around -4 degrees at 3000 metres. In the high altitudes of the Tauern, the southerly wind will pick up slightly in the evening (peaks of up to 50 km/h) and a few denser clouds will appear.

Monday night will be cloudy to very cloudy and the temperature will only drop by a few degrees during the night. The snow surface will crust can form less well.
