Southern Adamello, Adamello - Presanella, Northern Brenta - Peller, Southern Brenta, Sole, Pejo and Rabbi, Maddalene


Danger level
Danger Level 2 - Moderate above the treeline
Danger Level 1 - Low above the treeline
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW
Wet snow, N-NE-E-SE-S-SW-W-NW


Caution is to be exercised on wind-loaded slopes. As a consequence of warming and solar radiation an unfavourable avalanche situation will be encountered in some regions.

Fresh wind slabs represent the main danger. As a consequence of a moderate to strong northwesterly wind, sometimes easily released wind slabs formed in all aspects. As the day progresses in particular on wind-loaded slopes there will be a gradual increase in the danger of gliding avalanches and moist snow slides. The more recent wind slabs are clearly recognisable, in particular adjacent to ridgelines and in gullies and bowls at high altitudes and in high Alpine regions. In particular in gullies and bowls the wind slabs have increased in size additionally.
Weakly bonded old snow: Individual avalanche prone locations for dry avalanches are to be found in particular on steep north facing slopes above approximately 2300 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack in little used backcountry terrain. Avalanches can be released by large loads and reach medium size. Gradual increase in danger of dry and moist avalanches as a consequence of warming.
In steep terrain there is a danger of falling on the hard snow surface.

Snowpack

The fresh wind slabs remain in some cases prone to triggering in all aspects above the tree line.
Faceted weak layers exist in the old snowpack in particular on west, north and east facing slopes. This applies in particular above approximately 2300 m, especially in little used backcountry terrain.

Tendency

The avalanche danger will increase a little during the day. Fresh wind slabs require caution.

Danger level
Danger Level 2 - Moderate above the treeline
Danger Level 1 - Low above the treeline

Fresh wind slabs require caution. As a consequence of warming and solar radiation an unfavourable avalanche situation will be encountered in some regions.

Fresh wind slabs require caution. There is a danger of falling on the icy crust. The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 1800 m, and adjacent to ridgelines and in gullies and bowls in all aspects. These places are clearly recognisable to the trained eye. Mostly the dry avalanches are medium-sized and can be released in some cases by a single winter sport participant. Isolated avalanche prone weak layers exist in the snowpack especially on steep shady slopes. Gradual increase in avalanche danger as a consequence of warming.

Snowpack

The more recent wind slabs are in some cases prone to triggering above the tree line. These are mostly small. The older wind slabs have bonded well with the old snowpack. The snowpack will be subject to considerable local variations.

Tendency

The avalanche danger will increase a little during the day. Fresh wind slabs require caution.

Fresh wind slabs require caution.

The fresh snow and wind slabs must be evaluated with care and prudence in all aspects above the tree line. In steep terrain there is a danger of falling on the hard snow surface. The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 1800 m and adjacent to ridgelines. These places are rare and are clearly recognisable to the trained eye. As a consequence of warming and solar radiation a moderate danger of gliding avalanches and moist snow slides will be encountered in some regions. In very isolated cases the gliding avalanches are large.

Snowpack

The fresh wind slabs are poorly bonded with the old snowpack in particular on very steep shady slopes above the tree line.

Tendency

The avalanche danger will increase a little during the day. Fresh wind slabs require caution.
