On Saturday, conditions will be mostly cloudy in the west with light precipitation, especially in the Jura. The east will be very sunny at first, becoming increasingly cloudy as the day progresses. During the night to Sunday there will be some widespread precipitation in the west, with a total of 5 to 10 cm of snow falling above approximately 1200 m by Sunday morning. On Sunday, the north will be very sunny, with the west turning increasingly sunny. In the south, both days will be mostly sunny with broken cloud cover. Winds will be light to moderate from westerly directions.
There will be barely any change to the avalanche hazard on Saturday, but it will decrease somewhat in the north on Sunday. In inneralpine regions and in the south, avalanche hazard will decrease only very slowly due to the weak old snowpack. The situation for snow sports remains critical away from marked and open pistes.

Conditions brightened up quickly in the west and south, while the east remained cloudy with light snowfall. The snowfall level dropped to between 600 and 1000 m.
From Wednesday to Thursday afternoon, above approximately 1000 m:
In total, the following amounts have fallen above approximately 1500 m in the two days since midday on Tuesday:
At midday at 2000 m, around -6\u00b0C in the north and -3\u00b0C in the south
In the west and north conditions will be mostly very cloudy with light precipitation from the morning onwards. The snowfall level will be between 600 and 1000 m. There will be sunny intervals on the Main Alpine Ridge in Valais and in the rest of Grisons, and it will be mostly sunny on the southern flank of the Alps and in Engadine.
From Friday morning to Friday afternoon above approximately 1200 m:
At midday at 2000 m, around -4\u00b0C
On the southern flank of the Alps and in Upper Engadine, the last six days\u2019 fresh and drifted snow has been deposited on a weak snowpack, resulting in numerous medium-sized and indeed large spontaneous avalanches. In these regions, avalanches can still be triggered very easily in the old snowpack in many areas, including remotely. Avalanches are also to be expected deeper in the snowpack in the inneralpine regions of Valais and Grisons, especially on northern and eastern slopes. The avalanche situation requires patience.
North of a line from the Rh\u00f4ne to the Rhine, snowdrift accumulations, some of which are prone to triggering, have formed in recent days, and these are now covered with fresh snow. On Friday, the westerly winds will result in mostly small snowdrift accumulations. Weak layers deeper in the snowpack are less prone to triggering in these regions and such hazardous zones are rarer than in other regions.
