Avalanche bulletin for Saturday, 31 January 2015

In Valais a very critical avalanche situation will be encountered in some regions

Edition: 31.1., 08:00 Next update: 31.1., 17:00 Validity

Level 3, considerable

Fresh snow and snow drifts

Avalanche prone locations
In all aspects above approximately 1600m.

In all aspects above approximately 1600m.

Danger description

The fresh snow and snow drift accumulations of the last few days are very prone to triggering. Even single winter sport participants can release avalanches very easily, including medium-sized ones. Individual medium-sized to large natural avalanches are possible as before. Backcountry touring calls for great caution and restraint.

Full-depth avalanches

Mostly small full-depth avalanches are possible on cut and grassy slopes, in particular at low and intermediate altitudes.

Information on snowpack and weather

Level 3, considerable

Fresh snow and snow drifts

Avalanche prone locations
In all aspects above approximately 1800m.

In all aspects above approximately 1800m.

Danger description

The fresh snow and snow drift accumulations are prone to triggering. Snow drift accumulations can in some cases be released by a single winter sport participant. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. The number and size of avalanche prone locations will increase with altitude. Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger and careful route selection.

Information on snowpack and weather

Level 2, moderate

Snow drifts

Avalanche prone locations
In all aspects above approximately 2000m.

In all aspects above approximately 2000m.

Danger description

Fresh snow drift accumulations are mostly small but in some cases prone to triggering. The more recent snow drift accumulations are to be avoided in particular in very steep terrain. Careful route selection is recommended.

Information on snowpack and weather

Level 4, high

Fresh snow and snow drifts, old snow

Avalanche prone locations
In all aspects above approximately 2000m.

In all aspects above approximately 2000m.

Danger description

The fresh snow and snow drift accumulations are very prone to triggering. Even single winter sport participants can release avalanches very easily. Remote triggering is probable. Avalanches can release the weakly bonded old snow as well and reach a dangerous size. Natural avalanches are possible in isolated cases. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack. Backcountry touring calls for great caution and restraint.

Level 3, considerable

Fresh snow and snow drifts

Avalanche prone locations
In all aspects above approximately 1600m.

In all aspects above approximately 1600m.

Danger description

The fresh snow and snow drift accumulations are prone to triggering. Even single winter sport participants can release avalanches easily. These can in isolated cases reach medium size. Ski touring and other off-piste activities, including snowshoe hiking, call for experience in the assessment of avalanche danger and caution.

Level 3, considerable

Fresh snow and snow drifts

Avalanche prone locations
In all aspects above approximately 1200m.

In all aspects above approximately 1200m.

Danger description

The fresh and somewhat older snow drift accumulations are prone to triggering. Even single winter sport participants can release avalanches easily. Ski touring and other off-piste activities, including snowshoe hiking, call for extensive experience in the assessment of avalanche danger and great restraint.

Information on snowpack and weather

Level 3, considerable

Fresh snow and snow drifts, old snow

Avalanche prone locations
In all aspects above approximately 2000m.

In all aspects above approximately 2000m.

Danger description

The fresh snow and snow drift accumulations can be released by a single winter sport participant. Remote triggering is possible. Avalanches can additionally be released in the weakly bonded old snow in particular in little used backcountry terrain. Individual natural avalanches are possible, including medium-sized ones. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and caution.
