In the northeast a considerable avalanche danger will be encountered in some regions

Edition: 27.2., 17:00 Next update: 28.2., 08:00 Validity

Level 2, moderate

Old snow, snow drifts

Avalanche prone locations
In particular in southwest to north to southeast facing aspects above approximately 1800m.

In particular in southwest to north to southeast facing aspects above approximately 1800m.

Danger description

Avalanches can in isolated cases be released in near-surface layers especially at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Above approximately 3000 m: On Friday small snow drift accumulations have formed. These are to be evaluated with care and prudence.
Backcountry touring and other off-piste activities call for careful route selection.

Level 2, moderate

Snow drifts, old snow

Avalanche prone locations
In all aspects above approximately 1800m.

In all aspects above approximately 1800m.

Danger description

The mostly small snow drift accumulations of Friday can be released by a single winter sport participant in some cases. These avalanche prone locations are to be found especially adjacent to the ridge line and in pass areas. Above approximately 3000 m avalanche prone locations are more prevalent and the danger is slightly greater. Avalanches can additionally in some places be released in deeper layers also.
Backcountry touring and other off-piste activities call for careful route selection.

Level 3, considerable

Fresh snow and snow drifts

Avalanche prone locations
In particular in west to north to south facing aspects above approximately 2200m.

In particular in west to north to south facing aspects above approximately 2200m.

Danger description

The fresh snow and snow drift accumulations can be released easily, even by a single winter sport participant,. These avalanche prone locations are to be found especially adjacent to the ridge line and in pass areas and on very steep slopes. Avalanches can additionally in some places be released in deeper layers also. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection.

Level 2, moderate

Snow drifts, old snow

Avalanche prone locations
In particular in southwest to north to southeast facing aspects above approximately 2000m.

In particular in southwest to north to southeast facing aspects above approximately 2000m.

Danger description

The snow drift accumulations of the last few days can still be released in some cases. In high Alpine regions avalanche prone locations are more prevalent and the danger is slightly greater.
Additionally in very isolated cases avalanches can penetrate deep layers and reach medium size. These avalanche prone locations are to be found in particular in little used backcountry terrain. Backcountry touring and other off-piste activities call for careful route selection.
