The fresh fallen snow of the last few days and the freshly created snowdrift accumulations which often were generated by strong-velocity winds were deposited on top of an old snowpack surface which was strikingly marked by rain, wind and sun, in some places was also iced-over. On the northern flank of the Alps more than anywhere else there is a small amount of loose snow on the surface over widespread areas which can be transported by strong-velocity westerly winds on Friday night.
In particular from the central Valais over the northern Ticino as far as Grisons, very isolated avalanches can be triggered in the old snow at high altitudes. This applies to expansively metamorphosed (faceted) loose-snow layers either immediately beneath the rain crust which formed at the end of December or more deeply embedded inside the snowpack.

Following a clear and cold night, skies were frequently overcast during the daytime. During the afternoon in the western and northern regions there was a small amount of snowfall down to low lying regions.

in the western and the northern regions, only a few centimetres.

Temperatures at midday at 2000 m, -7 °C.

• Nocturnal winds were light;
• during the daytime increasing in velocity, in the afternoon blowing at strong velocity in some places in the eastern sector of the northern flank of the Alps, from westerly directions.
  

A small amount of snowfall is anticipated during the nighttime hours, falling down to low lying areas. During the daytime there will be intermittent sunshine before snowfall will set in once again during the afternoon. In the furthermost southern regions it will be dry and sunny in many places.

Between Friday afternoon and Saturday afternoon:

• northern flank of the Alps, Grisons north of Anterior Rhine, Jura region: 5 to 15 cm;
• in the other regions of Switzerland, less; in the furthermost southern regions i will remain dry.

At midday at 2000 m: -9 °C.

• Winds during the nocturnal hours will be blowing at moderate to strong velocity, intermittently at storm strength on the northern flank of the Alps and at high altitudes in general, temporarily from westerly directions;
• during the daytime at high altitudes and in the southern regions, strong-velocity northerly winds; in the other regions of Switzerland moderate strength westerly winds.
