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


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
Favourable situation above 2000m


Fresh snow and wind slabs above the tree line. The snowpack will be in most cases well bonded.

The mostly small wind slabs of the last few days can be released, especially by large additional loads, in all aspects above the tree line. In some places fresh snow and wind slabs are lying on an icy crust. Even in moderately steep terrain there is a danger of falling on the icy crust.

Snowpack

dp 6: cold, loose snow and wind

The fresh wind slabs are rather small and can be released by large loads in particular. These are clearly recognisable to the trained eye. The older wind slabs have bonded quite well with the old snowpack. The snowpack will be stable in particular in shady places that are protected from the wind. In some places fresh snow and wind slabs are lying on an icy crust.

Tendency

Gradual decrease in danger of gliding avalanches and snow slides as the temperature drops.

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

Gliding snow above 2600m, E-SE-S-SW-W


Fresh wind slabs require caution.

The fresh wind slabs must be evaluated with care and prudence in all aspects above the tree line. They are mostly easy to recognise but can be released easily. In the regions exposed to heavier precipitation caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. Individual gliding avalanches are possible, but they can reach medium size, 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 6: cold, loose snow and wind
dp 2: gliding snow

The wind has transported the fresh snow significantly. The fresh wind slabs are clearly recognisable to the trained eye. These are lying on soft layers in particular on shady slopes above the tree line. The older wind slabs have bonded quite well with the old snowpack.
The old snowpack will be moist below the tree line.

Tendency

Gradual decrease in danger of gliding avalanches and snow slides as the temperature drops.
