Regions
Texel Mountains, Durreck Range, Val Müstair Alps, Langtaufers, Schnals Ridge, Southern Stubai Alps, Southern Zillertal Alps and High Tauern, Saldurn-Mastaun Ridge


Danger level
Danger Level 2 - Moderate above 2200m
Danger Level 1 - Low above 2200m
Avalanche Problem
Wind-drifted snow above 2200m, N-NE-NW
Persistent weak layer above 2800m, N-NE-E-W-NW


Wind slabs require caution, in particular at high altitudes and in high Alpine regions.

Fresh and somewhat older wind slabs can be released by a single winter sport participant in some cases in particular on very steep shady slopes above approximately 2200 m. These avalanche prone locations are clearly recognisable to the trained eye.
Weakly bonded old snow: In isolated cases avalanches can be released in the old snowpack and reach dangerously large size. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack in little used backcountry terrain.

Snowpack

dp 6: cold, loose snow and wind

In some regions up to 5 cm of snow. will fall. The fresh and older wind slabs are to be evaluated with care and prudence on steep shady slopes at high altitudes and in high Alpine regions. Faceted weak layers exist in the old snowpack. The snowpack will be subject to considerable local variations.

Tendency

The backcountry touring conditions are generally favourable. Moderate, level 2.

Regions
Sexten Dolomites, Eastern Pfunderer Mountains, Western Rieserferner Mountains, Western Deferegger Alps, Ortler Range, Ulten Valley, Eastern Rieserferner Mountains, Northern Dolomites of Fiemme, Glockner Range, Gröden Dolomites, Eastern Deferegger Alps, Prags Dolomites, Sarntal Alps, Schober Mountains, Western Pfunderer Mountains, Lienzer Dolomites


Danger level
Danger Level 2 - Moderate above 2200m
Danger Level 1 - Low above 2200m
Avalanche Problem
Wind-drifted snow above 2200m, N-NE-NW


As the temperature drops a widespread favourable avalanche situation will prevail.

Fresh wind slabs require caution. The avalanche prone locations are to be found in particular on steep shady slopes above approximately 2200 m, especially in gullies and bowls, and behind abrupt changes in the terrain. These places are clearly recognisable to the trained eye. Mostly the avalanches are small.
In steep terrain there is a danger of falling on the hard snow surface.

Snowpack

dp 6: cold, loose snow and wind

Some snow will fall in some regions. The fresh and somewhat older wind slabs are mostly small and can only be released in isolated cases. In some cases relatively hard layers of snow are lying on old snow containing large grains. This applies especially on shady slopes at high altitudes and in high Alpine regions. The snowpack will be subject to considerable local variations.

Tendency

The backcountry touring conditions are generally favourable.

Regions
Prealps, Cembra Valley, Bondone and Stivo, Vallarsa, Western Nonsberg Alps, Folgaria - Laverone, Ledro Valley, Eastern Nonsberger Alps, Paganella, Marzola - Valsugana


Danger level
Danger Level 1 - Low
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-NW


Wind slabs require caution.

The mostly small wind slabs of the last few days must be evaluated with care and prudence in all aspects. 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. In steep terrain there is a danger of falling on the icy crust.

Snowpack

More recent wind slabs are poorly bonded with the old snowpack in particular on very steep shady slopes above the tree line. The surface of the snowpack will freeze to form a strong crust only at high altitudes. The old snowpack will be subject to considerable local variations.

Tendency

The old snowpack remains stable in all aspects. Wind slabs are to be evaluated with care and prudence.
