Snowpack

The snowpack is characterised by stormy weather, warmer temperatures and sometimes rain. Windward locations such as peaks, ridgelines and crests are often blown off down to the ground, or the crusts from November are blown off. There are large, often compact and hard snowdrift accumulations at a distance from ridgelines. The surface of the snowpack is often icy and slippery. There is hardly any transportable snow left. The snowpack structure is generally favourable. However, individual fractures in near-surface layers or also in deeper layers are still possible.

There are many glide cracks below approximately 2400 m, except on the southern flank of the Alps. So far, gliding avalanches have mainly occurred on east-, south- and west-facing slopes. They were less prevalent on northern slopes and mostly occurred below approximately 2200 m. Gliding avalanches can be triggered at any time of day or night and can be quite large.

Weather forecast until Wednesday, 27.12.2023

The night will be mostly clear and during the day it will be mostly sunny in the mountains.

Trend until Friday, 29.12.2023

After a largely clear night, Thursday will be partly sunny in the east with foehn winds, otherwise it will be variable to very cloudy. Some precipitation may fall in the far west. The temperature will drop to 0 °C at 2000 m. It will brighten during Thursday night, with some sunny spells during the day. There will continue to be a moderate to strong westerly wind.

The danger of dry avalanches will continue to decrease. Gliding avalanches are still expected, with even large ones anticipated in regions with a lot of snow.
