Snowpack

In places above approximately 2200 m that are generally protected from the wind, this week’s new snow and snowdrift are lying on a weak layer with an angular structure. In this layer, people may still occasionally release avalanches. In addition, some of the snowdrift accumulations that have formed in the last few days with the change in wind direction are still prone to triggering.

With increasing southwesterly winds, the loose, near-surface snow will be transported on Monday. Bound, easily releasable snowdrift accumulations will be formed.

With rain on Monday afternoon, the surface of the snowpack will be moistened up to 2000 m. Gliding avalanches are still possible.

Weather forecast until Monday, 22.01.2024

After a mostly clear night on Monday, it will turn increasingly cloudy from the northwest from the early morning. Precipitation will set in in the west and north in the afternoon, falling as snow above 1600 to 2000 m. In the inneralpine regions and in the south it will initially still be bright, turning increasingly cloudy as the day progresses.

New snow

Above approximately 2200 m, around 5 cm of snow will fall in the west on Monday afternoon.

In the Jura, 5 to 10 mm of rain will fall right up to the peaks.

Temperature

Temperatures will rise. At midday at 2000 m, +4 °C in the north and +1 °C in the south. They will fall again from Monday afternoon.

Wind

• Winds will be moderate to strong from the southwest to west, strong to storm force during the day in the west and north.
• As the day progresses, a moderate to strong foehn wind will blow from the south in the foehn valleys of the north.

TrendTuesday

Precipitation will fall in the north during Monday night into Tuesday, but it will remain dry on the central part of the southern flank of the Alps. The snowfall level will drop from 2000 m to around 1200 m. During the day, it will initially be very cloudy in the north, with some snow still falling in the east. It will be brighter for a time, and partly sunny in inneralpine regions, before turning increasingly cloudy again in the afternoon. In the far west and on the northern flank of the Alps from the eastern Bernese Alps to the Alpstein region, 10 to 30 cm of snow will fall above 2000 m, with less elsewhere. It will be mostly sunny in the south. Moderate to strong northwesterly winds will blow at high altitudes. These will be strong to storm force on the Main Alpine Ridge.

The danger of dry avalanches will increase, especially in the west and north. Gliding avalanches are still possible.

Wednesday

A little precipitation will fall in the north and west during Tuesday night into Wednesday. The snowfall level will rise to 2200 m. During the day it will be mostly very cloudy in the north and there will be a little precipitation in the afternoon, especially on the northern flank of the Alps and in the northern regions of Grisons. This will fall as snow above 1800 m. It will be mostly sunny in the south. There will be strong to storm force west to northwesterly winds.

There will be hardly any change in the avalanche danger.
