Regions
Prealps, Cembra Valley, Bondone and Stivo, Ledro Valley, Paganella


Danger level
Danger Level 4 - High above the treeline
Danger Level 3 - Considerable above the treeline
Avalanche Problem
Wet snow above the treeline, N-NE-E-SE-S-SW-W-NW
Gliding snow above 2200m


As a consequence of fresh snow and stormy weather a critical avalanche situation will be encountered in some regions. As the snowfall level rises individual medium-sized and, in isolated cases, large moist loose snow avalanches are possible below approximately 2200 m.

Natural avalanches must be expected. On steep grassy slopes numerous medium-sized and, in many cases, large gliding avalanches are to be expected below approximately 2200 m. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. As the precipitation becomes more intense the prevalence and size of the avalanche prone locations will increase as the day progresses, in particular in the east. The danger of wet and gliding avalanches will increase during the day. During the morning as well, individual, then as the precipitation becomes heavier more wet avalanches are to be expected.

Snowpack

dp 3: rain
dp 2: gliding snow

Over a wide area 40 to 80 cm of snow, and even more in some localities, has fallen thus far, especially in the northeast.
The snowpack will be generally prone to triggering. Over a wide area fresh snow and wind slabs are lying on soft layers, especially above the tree line. The old snowpack will be unstable in high Alpine regions. Dry avalanches can be released in near-ground layers.
The snowpack will be moist at low and intermediate altitudes.

Tendency

A critical avalanche situation will persist. Considerable, level 3.

Danger level
Danger Level 4 - High
Avalanche Problem
Gliding snow above 2500m, N-NE-E-SE-S-SW-W-NW
Wind-drifted snow above 2000m, N-NE-E-SE-S-SW-W-NW


Numerous large and, in many cases, very large natural avalanches are to be expected as the precipitation becomes more intense. A critical avalanche situation will prevail.

As the precipitation becomes more intense numerous natural avalanches are to be expected, even very large ones. Gliding avalanches and dry slab avalanches are the main danger. On steep grassy slopes numerous medium-sized and large gliding avalanches are to be expected below approximately 2500 m. In the regions where a lot of rain falls the danger will increase more quickly.
As a consequence of warming, the likelihood of dry slab avalanches being released will increase appreciably. Numerous large and, in many cases, very large avalanches are to be expected, this applies in particular from early morning. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.
Additionally in some places dry avalanches can also be released in near-ground layers and reach very large size as the day progresses. This applies in all aspects in high Alpine regions.
Outside marked and open pistes a critical avalanche situation will prevail.

Snowpack

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

Over a wide area 50 to 80 cm of snow, and up to 120 cm in some localities, fell. Over a wide area 50 to 80 cm of snow, and even more in some localities, will fall above approximately 1500 m, especially in the east. The wind will be strong to storm force. As a consequence of fresh snow and a storm force southerly wind, extensive wind slabs will form in all aspects.
The snowpack will be generally prone to triggering. Over a wide area fresh snow and wind slabs are lying on soft layers, especially above approximately 2000 m. The old snowpack will be unstable in high Alpine regions. Dry avalanches can be released in near-ground layers.
The snowpack will become wet all the way through at low and intermediate altitudes.

Tendency

Gradual decrease in avalanche danger.
