Avalanche bulletin through Wednesday, 18 January 2017

Considerable avalanche danger will be encountered over a wide area

Edition: 17.1., 17:00 Next update: 18.1., 08:00 Validity

Level 3, considerable

Old snow

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

In particular in southwest to north to east facing aspects above approximately 2400m.

Danger description

The fresh snow and snow drift accumulations of last week are lying on top of a weakly bonded old snowpack, especially on north facing slopes above approximately 2200 m. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Even single winter sport participants can release avalanches. Mostly these are small. Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger.

Snow drifts

As a consequence of the northeasterly wind avalanche prone snow drift accumulations have formed, in particular adjacent to the ridge line. They are to be evaluated with care and prudence.

Level 3, considerable

Old snow

Avalanche prone locations
In all aspects above approximately 2200m.

In all aspects above approximately 2200m.

Danger description

The fresh snow and snow drift accumulations of last week are lying on top of a weakly bonded old snowpack, especially on north facing slopes above approximately 2200 m. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Single winter sport participants can release avalanches, including dangerously large ones. Remote triggering is possible. Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger and caution.

Snow drifts

Adjacent to the ridge line clearly visible snow drift accumulations have formed. These are to be evaluated with care and prudence in steep terrain.

Level 3, considerable

Snow drifts, old snow

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

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

Danger description

As a consequence of the northeasterly wind snow drift accumulations have formed. This applies in particular adjacent to the ridge line and in pass areas as well as at elevated altitudes. The fresh snow drift accumulations can be released by a single winter sport participant in some cases. They are clearly recognisable to the trained eye. They are to be avoided in steep terrain.
Avalanches can additionally be released in the weakly bonded old snow, mostly by large additional loads. This applies especially on north facing slopes above approximately 2200 m. They can reach medium size. Caution is to be exercised in areas where the snow cover is rather shallow as well as at transitions from a shallow to a deep snowpack.

Level 3, considerable

Snow drifts

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

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

Danger description

As a consequence of the Bise wind sometimes large snow drift accumulations have formed. These can be released by a single winter sport participant in some cases. The fresh snow drift accumulations are clearly recognisable to the trained eye. They are to be avoided in steep terrain.

Level 2, moderate

Snow drifts, old snow

Avalanche prone locations
In all aspects above approximately 2000m.

In all aspects above approximately 2000m.

Danger description

Fresh and somewhat older snow drift accumulations are in some cases still prone to triggering. They are mostly only small. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. In isolated cases avalanches can penetrate deep layers. This applies in particular on north facing slopes above approximately 2200 m. Careful route selection is recommended.
