The layers of fresh snow and freshly generated snowdrifts from the beginning of this week are settling and stabilizing to an increasing degree. Particularly on shady slopes, these layers can still be triggered in some places. As a consequence of strong-velocity southwesterly winds, furthermore, fresh snowdrift accumulations are being generated at high altitudes. From the southern Valais over the northern Ticino as far as Grisons, weak layers exist inside the old snowpack. Avalanches can fracture down to more deeply embedded layers in the snowpack in those regions and subsequently grow to large size.
As a result of solar radiation and daytime warming, the snowpack surface on steep sunny slopes has become moist and during Wednesday night it will form a melt-freeze crust which is not capable of bearing loads. Particularly in the western and the northern regions, gliding avalanches continue to be possible.

On Tuesday night in the eastern regions a small amount of fresh snow was registered. The snowfall level lay at 1000 m. During the daytime on Wednesday it was predominantly sunny in the western and the southern regions, in the eastern regions it turned increasingly sunny after the residual clouds dispersed during the course of the morning.

Eastern sector of the northern flank of the Alps, northern Grisons, Lower Engadine: as much as 5 cm.

Temperatures rose, at midday at 2000 m, -2 °C in the northern regions and 2 °C in the southern regions.

• Winds at high altitudes on Tuesday night were blowing at moderate to strong velocity, at light to moderate strength in western regions, from northerly to northwesterly directions;
• during the daytime on Wednesday, winds were blowing at light to moderate strength, subsequently shifting to easterly, then to southwesterly during the afternoon.
  

In spite of some cloudbanks it will be quite sunny. During the afternoon, heavy cloud cover will move in from the west.

-

Temperatures will drop from the west, at midday at 2000 m, between -2 °C in the western regions and 0 °C in the eastern regions.

• Wind in the northern regions will be blowing at moderate to strong velocity from southwesterly directions at high altitudes; in the upper Alpine valleys foehn wind will temporarily prevail;
• in the southern regions, light to moderate winds will be blowing from southwesterly directions.
