Snowpack

New snow and drift snow from the night into Friday are often lying on an unfavourable old snow surface. They are often still prone to triggering.

There are widespread faceted weaklayers deep in the snowpack. North of a line between the Rhone and Rhine, these are often covered by thick, compact layers of snow. Avalanches in deeper layers may only be triggered in isolated cases and especially in places with little snow. In other regions, avalanches may still be triggered in weak layers near the ground and may still become large. Especially along the Main Alpine Ridge in the Grisons, in the Upper Engadine and in central Ticino there is still only little snow. In these regions avalanches may become up to medium in size.

In the northern and western regions with a lot of snow, medium and occasionally large gliding avalanches are still possible.

Weather review for Friday, 03.01.2025

During the night into Friday, it snowed widely down to low altitudes. During the day it was increasingly sunny, first in the south and west, then also in the east.

Fresh snow

The snowfall level was at low altitude. It snowed during the night into Friday:

• Extreme west of Lower Valais, northern flank of the Alps: 20 to 30 cm, up to 40 cm particularly in the northern parts of the Gotthard region
• Jura, rest of Valais: 10 to 20 cm
• Rest of northern Ticino, northern and rest of central Grisons, Silvretta, Samnaun: 5 to 10 cm
• further south: less or dry

Temperature

At midday at 2000 m, between -9 °C in the north and -3 °C in the south.

Wind

• During the night into Friday, initially strong from the west
• Moderate to strong winds from the north to northwest during the second half of the night and in the late morning at high altitudes

OutlookSunday

There will be some precipitation over a wide area in the north during the night into Sunday. The snowfall level will increase to 2200 to 2400 m on the northern flank of the Alps and in Valais, and will remain lower for longer in northern and central Grisons. During the day it will be quite sunny in the west. There will be strong to stormy westerly to southwesterly winds at high altitudes. It will be mostly very cloudy on the southern flank of the Alps. The zero-degree level will be around 3000 m. The danger of dry avalanches will increase in the north with precipitation. With rain, more moist snow slides and gliding avalanches are expected in the north at intermediate and low altitudes. The avalanche danger will not change significantly in the south.

Monday

It will be quite sunny in the north. In the south, it will be mostly very cloudy with some snow falling above 1000 m. There will be strong to stormy southwesterly winds at high altitudes, and storm-force foehn wind from the south in the Alpine valleys. The avalanche danger will begin to increase in the south, but will not change significantly in the north.
