Waadtländer Voralpen

The snowpack is moist. In particular on very steep north facing slopes individual wet snow slides are possible. Restraint should be exercised because avalanches can sweep people along and give rise to falls.

The fresh fallen snow will be deposited atop a predominantly moist snowpack surface. Only on steep north-facing slopes above approximately 2600 m is the surface dry and, to some extent, loosely-packed. The slab avalanches triggered by persons during the last three days which have been reported were triggered above 3000 m in dry, near-surface layers, predominantly on north-facing slopes. The old snowpack is thoroughly wet on south-facing slopes far up into high alpine regions, on west-facing and east-facing slopes it is wet below approximately 3000 m, and on north-facing slopes below approximately 2600 m.

Nocturnal skies on Thursday were clear, apart from cloudbanks in the western regions moving through. During the daytime hours on Friday it was predominantly sunny, accompanied by cloudbanks moving through from the west. Fresh snow: - Temperature: At midday at 2000 m, between +8 °C in the western regions and +5 °C in the remaining regions of Switzerland. Wind: Winds were blowing from northerly directions,

• Temperature: Temperatures are expected to drop. At midday at 2000 m: between +3 °C in the western regions and +1 °C in the remaining regions of Switzerland. Wind: Winds will be blowing from southwesterly directions, subsequently shifting to northwesterly,

On Sunday, particularly in the western regions, it will be predominantly sunny; in the eastern regions conditions will be variable, accompanied by showers. On Monday, variable conditions are anticipated in all regions, accompanied by showers in the afternoon. On Sunday, northerly winds will be blowing intermittently at moderate strength at high altitudes, otherwise at light strength; light strength winds will continue on Monday. Temperatures are expected to rise somewhat, particularly on Monday. The danger of dry-snow avalanches is not expected to change significantly, the danger of wet-snow avalanches will become increasingly subject to a slight daytime danger cycle.
