In some places avalanches can be triggered in the old snow and reach large size in isolated cases. This applies especially on shady slopes above approximately 2800 m. In addition the wind slabs of Sunday are prone to triggering in some cases still. Backcountry touring calls for careful route selection. The Avalanche Warning Service currently has only a small amount of information, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.

Snowpack & Weather

Snowpack

The snow line on northern slopes is at 1800 m and around 400 m higher on southern slopes. At high altitudes, there are patches of continuous snowpack in gullies and bowls on shady slopes. The snow is significantly deeper above 2800 m.

In particular on north-facing slopes above approximately 2800 m and generally in the high Alpine regions, near-ground layers have become faceted. As demonstrated by avalanches triggered on Sunday, in these regions avalanches can start in the old snowpack and sometimes become large.

Outlook

Conditions will be mostly sunny in the mountains on Thursday and Friday. Temperatures will remain very mild with a zero-degree level above 3000 m and the southwesterly wind will be light to moderate.

Avalanche risk will decrease.
