Adamello - Presanella, Northern Brenta - Peller, 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, N-NE-E-SE-S-SW-W-NW


Fresh wind slabs require caution.

As a consequence of fresh snow and a strong wind, wind slabs formed in some places. Fresh wind slabs are mostly shallow but prone to triggering. The avalanche prone locations are to be found in all aspects, especially in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can be released in the old snowpack especially at transitions from a shallow to a deep snowpack. The avalanche prone locations are barely recognisable because of the poor visibility. In steep terrain there is a danger of falling on the hard snow surface.

Snowpack

dp 6: cold, loose snow and wind

In some localities up to 5 cm of snow. fell. Over a wide area fresh snow and wind slabs are lying on a hard crust. The snowpack will be subject to considerable local variations. Individual weak layers exist deep in the snowpack on shady slopes.

Tendency

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

Regions

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


The backcountry touring conditions are mostly favourable.

The sometimes strong wind has transported only a little snow. The no longer entirely fresh wind slabs have bonded quite well with the old snowpack. These can only be released by large loads in most cases. The avalanche prone locations are to be found in particular on steep northwest to north to southeast facing slopes above approximately 2000 m, especially in gullies and bowls, and behind abrupt changes in the terrain. These places are clearly recognisable to the trained eye.
In steep terrain there is a danger of falling on the icy crust.

Snowpack

Little snow has fallen. 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. Individual weak layers exist deep in the snowpack on shady slopes. The snowpack will be subject to considerable local variations. The surface of the snowpack will freeze to form a strong crust and will soften during the day. Below approximately 2000 m only a little snow is lying on south and southwest facing slopes.

Tendency

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

Danger level
Danger Level 1 - Low


The snowpack will be generally well bonded.

The sometimes strong wind has transported only a little snow. The no longer entirely fresh wind slabs have bonded quite well with the old snowpack. These can only be released by large loads in most cases. The avalanche prone locations are to be found in particular on steep northwest to north to southeast facing slopes above approximately 1800 m, especially in gullies and bowls, and behind abrupt changes in the terrain. These places are clearly recognisable to the trained eye.
