Avalanche bulletin through Monday, 27 March 2017

In southern Valais a considerable avalanche danger will be encountered over a wide area

Edition: 26.3., 17:00 Next update: 27.3., 08:00 Validity

Level 2, moderate

Snow drifts

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

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

Danger description

The snow drift accumulations of the last few days are in some cases still prone to triggering. They can especially at their margins be released by people. The avalanche prone locations are to be found in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Careful route selection is recommended.

Wet avalanches as day progresses

As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of wet and full-depth avalanches. Small to medium-sized full-depth and wet avalanches are to be expected below approximately 2600 m, especially on very steep east, south and west facing slopes.

Level 2, moderate

Snow drifts, old snow

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

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

Danger description

The more recent snow drift accumulations are to be evaluated with care and prudence in steep terrain. These are rather small. They are to be found in particular adjacent to the ridge line and in gullies and bowls.
Avalanches can additionally in isolated cases be released in deep layers, even by a single winter sport participant. Caution is to be exercised in particular on steep, rather lightly snow-covered shady slopes in little used backcountry terrain. These avalanche prone locations are rare but barely recognisable, even to the trained eye. Avalanches can reach medium size.

Wet avalanches as day progresses

As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of wet and full-depth avalanches. Small to medium-sized full-depth and wet avalanches are to be expected below approximately 2600 m, especially on very steep east, south and west facing slopes.

Level 3, considerable

Snow drifts, old snow

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

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

Danger description

The more recent snow drift accumulations are prone to triggering. Single snow sport participants can release avalanches. These can in some cases penetrate deep layers and reach dangerously large size. This applies in particular on west, north and east facing slopes. Off-piste activities call for experience in the assessment of avalanche danger.

Small to medium-sized full-depth and wet avalanches are to be expected below approximately 2600 m, especially on very steep east, south and west facing slopes.

Level 2, moderate

Old snow, snow drifts

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

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

Danger description

Avalanches can be released in deep layers, even by small loads in isolated cases. Caution is to be exercised in particular on steep, rather lightly snow-covered shady slopes in little used backcountry terrain. These avalanche prone locations are rare but barely recognisable, even to the trained eye. Avalanches can reach medium size. Very steep slopes are to be traversed by snow sport participants one at a time.
The small snow drift accumulations of the last few days are to be evaluated with care and prudence in very steep terrain. They are to be found in particular adjacent to the ridge line and in gullies and bowls.

Wet avalanches as day progresses

As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of wet and full-depth avalanches. Small to medium-sized full-depth and wet avalanches are to be expected below approximately 2600 m, especially on very steep east, south and west facing slopes.

Level 1, low

Snow drifts

Individual avalanche prone locations for dry avalanches are to be found in particular on extremely steep shady slopes, especially at high altitude. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.

Wet avalanches as day progresses

The danger of full-depth and wet avalanches will increase during the day, reaching danger level 2 (moderate). Small to medium-sized full-depth and wet avalanches are to be expected, especially on very steep east, south and west facing slopes.
