Danger level
Danger Level 1 - Low above 2500m
Danger Level 2 - Moderate above 2500m
Avalanche Problem
Persistent weak layer above 2400m above the treeline, SE-S-SW-W


The snowpack will be well bonded in the early morning. Fresh wind slabs require caution, especially adjacent to ridgelines and in pass areas.

As a consequence of warming during the day and solar radiation individual gliding avalanches are possible, but they can reach medium size, especially at the base of rock walls and on steep grassy slopes below approximately 2400 m. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. Areas with glide cracks are to be avoided as far as possible. The fresh and older wind slabs must be evaluated with care and prudence in all aspects at elevated altitudes. They are mostly easy to recognise but can be released by large loads in particular. 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.

Snowpack

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

The wind has transported only a little snow. 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 snowpack will be well bonded until the middle of the day. Temporary increase in danger as a consequence of warming during the day and solar radiation.

Tendency

Moderate, level 2.

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


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 2000m, SE-S-SW-W


In these regions the snowpack is well bonded. The fresh and older wind slabs represent the main danger, especially adjacent to ridgelines and in pass areas.

The mostly small wind slabs can be released, especially by large additional loads, in all aspects above the tree line. 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. As a consequence of warming during the day and solar radiation individual gliding avalanches and moist snow slides are possible, but they will be mostly small.

Snowpack

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

The snowpack will be in most cases stable. Over a wide area fresh snow and wind slabs are lying on a hard crust. At low and intermediate altitudes hardly any snow is lying.

Tendency

Low, level 1. Temporary increase in danger of gliding avalanches as a consequence of warming during the day and solar radiation.
