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


Danger level
Danger Level 3 - Considerable above 1500m
Danger Level 2 - Moderate above 1500m
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-W-NW
Gliding snow above the treeline, E-SE-S-SW-W


More small and, in isolated cases, medium-sized moist loose snow avalanches are possible. The danger of moist avalanches will increase a little during the day.

On very steep grassy slopes more small and, in isolated cases, medium-sized gliding avalanches are possible. Elsewhere, avalanches can as before be released, in particular by large loads, in particular on wind-loaded slopes. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.

Snowpack

dp 2: gliding snow

40 to 100 cm of snow, and even more in some localities, has fallen in the last few days above approximately 1500 m. The snowpack remains moist at low and intermediate altitudes.
Over a wide area fresh snow and wind slabs are lying on soft layers, especially above the tree line. Moist avalanches can in isolated cases be triggered in deep layers and reach medium size.

Tendency

The danger of moist avalanches will increase a little during the day.

Danger level
Danger Level 3 - Considerable
Avalanche Problem
Gliding snow above 2600m, N-NE-E-SE-S-SW-W-NW
Wind-drifted snow above 2200m, N-NE-E-W-NW


Wind slabs above approximately 2200 m. Gliding snow requires caution.

On steep grassy slopes more gliding avalanches are possible, even quite large ones. Caution is to be exercised in areas with glide cracks. The fresh wind slabs are extensive and can in some cases be released easily especially at their margins. Caution is to be exercised in particular adjacent to ridgelines. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Large avalanches are possible in isolated cases, especially in high Alpine regions. Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger.

Snowpack

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

The snowpack will be moist at low and intermediate altitudes. In some places wind slabs are lying on soft layers, in particular on shady slopes as well as adjacent to ridgelines in high Alpine regions.

Tendency

The danger of gliding avalanches and snow slides will decrease gradually.

Regions
Cembra Valley, Western Nonsberg Alps


Danger level
Danger Level 2 - Moderate
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-W-NW
Gliding snow above the treeline, E-SE-S-SW-W


Individual mostly small moist loose snow avalanches are possible. The danger of moist avalanches will increase a little during the day.

On very steep grassy slopes individual mostly small gliding avalanches are possible. Elsewhere, avalanches can in some places be released, mostly by large loads, but they will be small in most cases, in particular on wind-loaded slopes. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.

Snowpack

dp 2: gliding snow

The snowpack remains moist at low and intermediate altitudes. Over a wide area fresh snow and wind slabs are lying on soft layers, especially above the tree line. Dry and moist avalanches can in isolated cases penetrate deep layers and reach medium size.

Tendency

The danger of moist and wet avalanches will increase a little during the day.
