As a result of fresh snow and winds, snowdrift accumulations are increasing significantly at heightened altitudes.
Beneath the freshly generated drifts, the snowpack on east-facing, south-facing and west-facing slopes is thoroughly wet below approximately 3000 m. On north-facing slopes the snowpack between 2200 m and 2400 m became thoroughly moist for the first time during the last few days, and was thereby weakened. In particular in Grisons, where the snowpack evidences marked weak layers, even large-sized slab avalanches have been observed in this altitude band.

During the night there were repeated bouts of precipitation, however also bright intervals in some places in the northern regions. During the morning hours in the furthermost eastern regions there were sunny spells. In the other regions of Switzerland skies were heavily overcast, accompanied by precipitation in the southern and western regions more than anywhere else. During the afternoon the precipitation extended increasingly to the other regions of Switzerland.

The snowfall level in the northwestern regions lay at approximately 1700 m, in the other regions of Switzerland between 2000 and 2400 m. Between Friday afternoon and Saturday afternoon, the following amounts of fresh snow were registered:

• central sector of the southern flank of the Alps: 20 to 40 cm;
• elsewhere 5 to 15 cm over widespread areas; in northern Grisons and the Lower Engadine it remained dry.

At midday at 2000 m in the northwestern regions at 0 °C, in the other regions of Switzerland at +3 °C.

• During the nocturnal hours in the western regions, westerly winds were blowing temporarily at moderate strength;
• in the other regions of Switzerland winds were blowing at light-to-moderate strength. During the daytime hours, strong-velocity southerly winds in some places.

In the early part of the night, intensive precipitation is anticipated over widespread areas. Subsequently the precipitation will come to an end in the southern regions. During the daytime in the Valais and in the southern regions, bright intervals are anticipated, in the northern and the eastern regions skies will remain heavily overcast accompanied by precipitation, although the intensity will slacken off significantly.

The snowfall level will descend from approximately 2000 m down to 1000 to 1400 m in the northern regions and to approximately 1600 m in the southern regions. Between Saturday afternoon and Sunday afternoon, the following amounts of fresh snow are expected:

• northern flank of the Alps, Ticino, Grisons: 20 to 40 cm;
• Valais: 10 to 20 cm.

At midday at 2000 m, between -2 °C in the northern regions and +2 °C in the southern regions.

• Winds in the early part of the night will by southerly, then shift to northerly;
• subsequently, winds will be blowing at moderate strength. To some extent, a strong-velocity northerly wind will be blowing in the southern regions and on the Main Alpine Ridge.
