Snowpack

New snowdrift accumulations will develop in the north on Thursday with fresh snow and westerly to northwesterly winds. These are prone to triggering at altitude. The underlying snowpack has been moistened with the mild temperatures, foehn wind and rain in recent days to intermediate altitudes and on sunny slopes to high altitudes and has settled. Above approximately 2800 m, a cohesive old snowpack has been lying for over a week. This contains weak layers of faceted crystals, especially on north-facing slopes. In such places, isolated avalanches can be triggered even at ground level.

With rain falling at times up to over 2000 m, gliding avalanches are possible on grassy slopes.

Weather forecast to Thursday, 28.11.2024

Precipitation will set in in the north during the night on Thursday. During the day heavy cloud with precipitation. The snowfall level during the night will be between 2200 m in the west and 1800 m in the east. It will drop to around 1800 m in the west and 1400 m in the east by Thursday evening. In the south it will be mostly sunny with a northerly wind.

• eastern Bernese Oberland, central and eastern parts of the northern flank of the Alps: 25 to 40 cm
• remaining northern flank of the Alps and northern Prättigau: 15 to 25 cm

OutlookFriday and Saturday

It will be mostly sunny in the mountains on both days. There will be a weak to moderate northeasterly wind. The zero-degree level will rise to 3000 m in the west and 2200 m in the east. It will be somewhat milder on Saturday.

The danger of dry avalanches will decrease. The sunshine will mean the possibility of loose snow avalanches from the rocks on Friday where fresh snow is lying.
