Snowpack

There are weak layers in the snowpack, especially near the surface, that are prone to triggering. These are gradually stabilising. There are hardly any weak layers in the lower part of the snowpack that are prone to triggering. To date, gliding avalanches have mainly occurred on east-, south- and west-facing slopes below around 2500 m and, less frequently, on north-facing slopes below around 2200 m. Gliding avalanches may still be triggered at any time of the day or night and may be large in regions with a lot of snow. Furthermore, isolated wet avalanches may occur on steep sunny slopes due to warming and solar radiation during the day.

Snow depths are above average at high altitudes, except in the south. They are below average to average at intermediate altitudes and generally in the south. On northern slopes, the snow lines in the north are between 1000 and 1400 m, while in the south and also in some parts of southern Valais they are between 1400 and 1800 m. On south-facing slopes, the snow lines are 200 to 400 m higher.

Weather forecast until Tuesday, 30.01.2024

As a result of the cloud cover during Monday night into Tuesday, there will be only partially clear skies. During the day, it will be fairly sunny and mild with occasional bursts of relatively dense cloud.

Trend until Thursday, 01.02.2024

On Wednesday, after a clear night, it will be sunny with high cloud cover. There will be weak to moderate westerly to northwesterly winds; the zero-degree level will drop to 2500 m.

On Thursday, it will become increasingly cloudy in the north and as the day progresses, precipitation will set in, falling as snow above 1400 m. It will be mostly sunny in the south. The winds will freshen up, with moderate to strong westerly to northwesterly winds expected as the day progresses.

The danger of dry avalanches will initially decrease slightly. On the central and eastern parts of the northern flank of the Alps, new snow and wind will see it increase a little during the day on Thursday. As a result of solar radiation, wet avalanches are possible on sunny slopes, especially on Wednesday. Gliding avalanches are still possible in all aspects.
