Regions
Western Lechtal Alps, Western Verwall Mountains, Allgäu Alps, Silvretta


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


Wind slabs above the tree line.

The fresh wind slabs can be released in particular on north to east to south facing aspects above the tree line, in particular adjacent to ridgelines. Avalanches can be released, even by small loads in isolated cases and reach medium size.
As a consequence of solar radiation individual small wet loose snow avalanches are possible. This applies in particular on very steep sunny slopes.
Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.

Snowpack

dp 6: cold, loose snow and wind

Up to 5 cm of snow, but less in some localities, will fall. The westerly wind will transport the fresh snow. In some cases wind slabs are lying on the smooth surface of an old snowpack. This applies in particular on north and east facing slopes above the tree line in places that are protected from the wind.

Tendency

Slight decrease in avalanche danger.

Regions
Brandenberg Alps, Western Kitzbühel Alps, Wilder Kaiser Mountains - Waidring Alps, Eastern Kitzbühel Alps


Danger level
Danger Level 1 - Low
Avalanche Problem
Favourable situation


The conditions are favourable.

Only a little snow is lying. On very steep shady slopes the avalanche prone locations are to be found adjacent to ridgelines and in gullies and bowls. They are rare and are easy to recognise. Avalanches can still in isolated cases be released, mostly by large loads.

Snowpack

No distinct weak layers exist in the snowpack in all altitude zones. The snowpack will be stable over a wide area. At low and intermediate altitudes hardly any snow is lying.

Tendency

Low, level 1.

Regions
Prealps, Cembra Valley, Bondone and Stivo, Vallarsa, Western Nonsberg Alps, Folgaria - Laverone, Ledro Valley, Marzola - Valsugana, Pine' - Mocheni Valley


Danger level
Danger Level 1 - Low
Avalanche Problem
Gliding snow above 2200m above 1800m, SE-S-SW-W


In these regions the snowpack is well bonded. Ground avalanches are possible in isolated cases as before, especially on steep grassy slopes.

Individual gliding avalanches are possible at any time, but they will be mostly small. The small wind slabs can be released, especially by large additional loads, in all aspects at elevated altitudes. Such avalanche prone locations are rare and are easy to recognise. Even in moderately steep terrain there is a danger of falling on the hard snow surface, after a clear night in particular.

Snowpack

dp 2: gliding snow

The snowpack will be in most cases stable. Over a wide area relatively hard layers of snow are lying on a moist old snowpack. At low and intermediate altitudes hardly any snow is lying.

Tendency

Low, level 1.

Danger level
Danger Level 1 - Low
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW
Gliding snow above 2300m above 1600m, SE-S-SW-W


Caution is to be exercised in areas with glide cracks. Ground avalanches are possible in isolated cases as before.

Individual gliding avalanches are possible at any time, but they will be mostly small, especially at the base of rock walls and on steep grassy slopes below approximately 2400 m. Areas with glide cracks are to be avoided as far as possible. The mostly small wind slabs have bonded well with the old snowpack in all aspects. They are easy to recognise and can be released by large loads in particular, especially adjacent to ridgelines and in pass areas,, in isolated cases also in gullies and bowls, and behind abrupt changes in the terrain.

Snowpack

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

The snowpack will be generally stable. The wind has transported only a little snow. The wind slabs are to be found in particular in the vicinity of peaks. These have bonded quite well with the old snowpack in all aspects. Over a wide area relatively hard layers of snow are lying on a moist old snowpack, in particular below the tree line as well as on sunny slopes at intermediate and high altitudes.

Tendency

Low, level 1.

Fresh wind slabs.

The fresh wind slabs must be evaluated with care and prudence in particular on northwest to north to southeast facing aspects, in particular adjacent to ridgelines. Single backcountry tourers can release avalanches easily. Avalanches are rather small. As a consequence of solar radiation individual small moist loose snow slides are possible. This applies especially on extremely steep sunny slopes. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. In addition a latent danger of gliding avalanches exists, in particular in case of releases originating from south facing starting zones below approximately 2600 m that have retained the snow thus far.

Snowpack

dp 6: cold, loose snow and wind

The fresh wind slabs are lying on soft layers. This applies at high altitudes and in high Alpine regions. The old snowpack will be moist on southeast, south and southwest facing slopes, in particular on steep sunny slopes below approximately 2600 m. The old snowpack will be generally well bonded.

Tendency

The wind will be moderate to strong in the vicinity of peaks.
