On Saturday it will be only partly sunny as a result of widespread cloudbanks. In the southern and also in the western regions, intermittent precipitation is anticipated. In the western and central sectors of the Main Alpine Ridge, 15 to 30 cm of fresh snow is expected above 2200 m by evening. Winds will be blowing intermittently at strong velocity from southerly directions.
The danger of dry-snow avalanches is expected to increase in the regions where there is precipitation. As a consequence of the fresh snow and winds, fresh snowdrift accumulations will be generated during the course of the day. The danger of wet-snow avalanches is not expected to change significantly.

On both the northern and the southern flank of the Alps skies will be variably cloudy to heavily overcast. Precipitation is anticipated from the south. The snowfall level will descend to 1700 m on Saturday night. On the Main Alpine Ridge and in Upper Valais, 20 to 40 cm of fresh snow is expected over widespread areas, on the Main Alpine Ridge from Monte Rosa into the Bernina region up to 60 cm of fresh snow. Winds at high altitudes will frequently be blowing at storm strength on Saturday night, during the daytime hours on Sunday at moderate to strong velocity, from southerly directions.
The danger of dry-snow avalanches is expected to increase significantly along the Main Alpine Ridge. In the remaining regions of Switzerland the danger will stem from freshly generated snowdrift accumulations more than anything else. The danger of wet-snow avalanches will tend to decrease as temperatures drop.
