Avalanche bulletin through Sunday, 30 April 2017

The conditions at elevated altitudes are wintry. Considerable avalanche danger will be encountered over a wide area

Edition: 29.4., 17:00 Next update: 30.4., 17:00 Validity

Level 3, considerable

Fresh snow and snow drifts

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

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

Danger description

The somewhat older snow drift accumulations represent the main danger. Avalanches can in some places be released by a single winter sport participant. They can in some cases reach medium size.
As a consequence of the foehn wind easily released snow drift accumulations will form. These are to be bypassed. Backcountry touring calls for experience in the assessment of avalanche danger.

Wet avalanches as day progresses

East, south and west facing slopes below approximately 2600 m: As a consequence of warming during the day and solar radiation small and, in isolated cases, medium-sized moist snow slides and avalanches are to be expected.

Information on snowpack and weather

Level 2, moderate

Fresh snow and snow drifts, old snow

Avalanche prone locations
In all aspects above approximately 2200m.

In all aspects above approximately 2200m.

Danger description

Somewhat older snow drift accumulations are mostly small but in some cases prone to triggering. The number and size of avalanche prone locations will increase with altitude.
Additionally avalanches can be released in deep layers. These avalanche prone locations are very rare. They are to be found in particular on very steep north facing slopes above approximately 2400 m.
Backcountry touring calls for careful route selection.

Snow drifts

Avalanche prone locations
In all aspects above approximately 1800m.

In all aspects above approximately 1800m.

Danger description

Somewhat older snow drift accumulations represent the main danger. They can be released, especially by large additional loads,. The snow drift accumulations are to be evaluated with care and prudence.

Level 2, moderate

Snow drifts, old snow

Avalanche prone locations
In particular in southwest to north to southeast facing aspects above approximately 2400m.

Danger description

Fresh and somewhat older snow drift accumulations are mostly small but can be released easily. The number and size of avalanche prone locations will increase with altitude.
