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


Danger level
Danger Level 3 - Considerable above 2200m
Danger Level 2 - Moderate above 2200m
Avalanche Problem
Gliding snow above 2400m, E-SE-S-SW-W
Wind-drifted snow above the treeline, N-NE-E-W-NW


Wind slabs are to be evaluated with care and prudence. Gliding snow at intermediate altitudes.

As a consequence of fresh snow and a moderate to strong southerly wind, large surface-area wind slabs formed in the last few days. They are mostly easy to recognise but can be released easily. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. Caution is to be exercised in particular adjacent to ridgelines. More gliding avalanches are possible, in particular medium-sized ones, especially in the regions with a lot of snow below approximately 2400 m. As the day progresses as a consequence of warming there will be only a slight increase in the danger of gliding avalanches and snow slides.

Snowpack

dp 2: gliding snow
dp 6: cold, loose snow and wind

The fresh wind slabs are in many cases rather small but can in some cases be released easily at their margins. These are lying on soft layers in particular on shady slopes above approximately 2000 m. The older wind slabs have bonded quite well with the old snowpack. Faceted weak layers exist deep in the old snowpack in particular on shady slopes. The snowpack remains quite moist, especially on steep sunny slopes below approximately 2000 m.

Tendency

Regions
Prealps, Cembra Valley, Bondone and Stivo, Vallarsa, Folgaria - Laverone, Ledro Valley, Marzola - Valsugana


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-W-NW
Wet snow above the treeline, E-SE-S-SW-W


Individual mostly small moist loose snow avalanches are possible. The danger of moist avalanches will increase a little during the day.

On very steep grassy slopes individual mostly small gliding avalanches are possible. Elsewhere, avalanches can in some places be released, mostly by large loads, but they will be small in most cases, in particular on wind-loaded slopes. The prevalence of avalanche prone locations will increase with altitude. The danger of moist slab avalanches will increase a little during the day.

Snowpack

dp 2: gliding snow

The snowpack remains moist at low and intermediate altitudes. Over a wide area fresh snow and wind slabs are lying on soft layers, especially above the tree line. Dry and moist avalanches can in isolated cases penetrate deep layers and reach medium size.

Tendency

In some localities increase in avalanche danger as a consequence of the fresh snow.

Regions
Western Tuxer Alps, Eastern Tuxer Alps, Glockturm Range, Weißkugel Range, Gurgler Range, Silvretta, Samnaun Mountains, Northern Oetz and Stubai Alps


Danger level
Danger Level 2 - Moderate
Avalanche Problem
Wind-drifted snow above 2300m, N-NE-NW
Gliding snow above 2600m, E-SE-S-SW-W


Fresh wind slabs represent the main danger. Slides can occur on steep grassy slopes.

As a consequence of a strong southerly wind, sometimes avalanche prone wind slabs formed. The fresh wind slabs can be released, especially by large additional loads, especially on very steep shady slopes above approximately 2300 m. In the Gurgler Range and in the Weißkugel Range and in the regions exposed to the foehn wind avalanche prone locations are more prevalent. Caution is to be exercised adjacent to ridgelines.
On steep grassy slopes only isolated moist snow slides are to be expected.

Snowpack

dp 6: cold, loose snow and wind
dp 2: gliding snow

In the Gurgler Range and in the Weißkugel Range up to 20 cm of snow. fell. Over a wide area strong southerly wind. The fresh wind slabs are lying on soft layers in particular on shady slopes above approximately 2300 m. They are clearly recognisable to the trained eye. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.
The old snowpack will be well bonded.
The snowpack will become generally moist. This applies in all aspects below approximately 2000 m as well as on sunny slopes below approximately 2400 m.

Tendency

Fresh wind slabs require caution, in particular in high Alpine regions. The snow sport conditions outside marked and open pistes are generally favourable.

Danger level
Danger Level 2 - Moderate
Avalanche Problem
Gliding snow above 2600m, E-SE-S-SW-W
Wind-drifted snow above 2400m, N-NE-E-W-NW


Gliding snow represents the main danger. Wind slabs require caution.

The sometimes avalanche-prone wind slabs must be evaluated with care and prudence in particular on west to north to east facing aspects above approximately 2400 m. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. Caution is to be exercised in particular adjacent to ridgelines. Individual gliding avalanches are possible, even quite large ones, especially in the regions with a lot of snow below approximately 2600 m. Areas with glide cracks are to be avoided as far as possible.

Snowpack

dp 2: gliding snow
dp 6: cold, loose snow and wind

The fresh wind slabs are clearly recognisable to the trained eye. They are mostly rather small but can in some cases be released easily at their margins. The older wind slabs have bonded quite well with the old snowpack. Faceted weak layers exist deep in the old snowpack above approximately 2800 m. The snowpack will become gradually moist, especially on steep sunny slopes below approximately 2000 m.

Tendency

In some localities increase in avalanche danger as a consequence of fresh snow and wind.

Danger level
Danger Level 1 - Low
Avalanche Problem
Wind-drifted snow above 2600m, N-NE-NW
Gliding snow above 2600m, E-SE-S-SW-W


Fresh wind slabs at high altitude. Slides can occur on steep grassy slopes.

Individual avalanche prone locations for dry avalanches are to be found in particular on very steep shady slopes above approximately 2600 m, especially adjacent to ridgelines. Such avalanche prone locations are rare and are easy to recognise. Individual gliding avalanches and moist snow slides are possible.

Snowpack

dp 2: gliding snow

The snowpack will be in most cases stable. The snowpack will become increasingly moist. This applies in all aspects below approximately 2000 m as well as on sunny slopes below approximately 2400 m. At low and intermediate altitudes hardly any snow is lying.

Tendency
