Regions
Southern Adamello, Adamello - Presanella, Northern Brenta - Peller, Southern Brenta, Sole, Pejo and Rabbi, Maddalene, Paganella


Danger level
Danger Level 3 - Considerable above the treeline
Danger Level 2 - Moderate above the treeline
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.

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 and on steep northeast, north and northwest facing slopes. As the snowfall becomes more intense a large number of moist loose snow avalanches are possible on Sunday, but they can be large in some cases. Caution is to be exercised in areas with glide cracks. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. 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
Prealps, Cembra Valley, Bondone and Stivo, Vallarsa, Folgaria - Laverone, Ledro Valley, Marzola - Valsugana


Danger level
Danger Level 2 - Moderate above the treeline
Danger Level 1 - Low above the treeline
Avalanche Problem
New snow, N-NE-E-W-NW
Wet 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.

Danger level
Danger Level 2 - Moderate
Avalanche Problem
Gliding snow above 2600m, E-SE-S-SW-W
Wind-drifted snow above 2300m, N-NE-E-W-NW


Gliding snow represents the main danger. Wind slabs require caution.

As a consequence of fresh snow and a strong to storm force southerly wind, sometimes easily released wind slabs formed in the last two days. They are to be evaluated with care and prudence. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. Caution is to be exercised in particular adjacent to ridgelines. Individual gliding avalanches are possible, even quite large ones, 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. On Monday as a consequence of warming there will be only a slight increase in the danger of gliding avalanches and snow slides.

Snowpack

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

The fresh wind slabs are clearly recognisable to the trained eye. They are mostly rather small but can in some cases be released easily at their margins. The older wind slabs have bonded quite well with the old snowpack. Faceted weak layers exist deep in the old snowpack above approximately 2800 m. The snowpack will become gradually moist, especially on steep sunny slopes below approximately 2000 m.

Tendency

Fresh wind slabs require caution.
