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


Danger level
Danger Level 3 - Considerable above 2600m
Danger Level 2 - Moderate above 2600m
Avalanche Problem
Gliding snow above 2500m, E-SE-S-SW-W
Wind-drifted snow above 2600m, N-NE-E-W-NW


Wind slabs are to be evaluated with care and prudence. Gliding snow at intermediate altitudes.

As a consequence of fresh snow and a moderate wind, sometimes avalanche prone wind slabs formed in the last few days in particular adjacent to ridgelines and in gullies and bowls as well as at high altitude. They are mostly easy to recognise but can be released easily. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. Caution is to be exercised in particular adjacent to ridgelines. More gliding avalanches are possible, in particular medium-sized ones, especially in the regions with a lot of snow below approximately 2500 m. As the day progresses as a consequence of the precipitation there will be only a slight increase in the avalanche danger.

Snowpack

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

The fresh wind slabs are in many cases rather small but can in some cases be released easily at their margins. These are lying on soft layers in particular on shady slopes above approximately 2000 m. The older wind slabs have bonded quite well with the old snowpack. Faceted weak layers exist deep in the old snowpack in particular on shady slopes. The snowpack remains quite moist, especially on steep sunny slopes below approximately 2000 m.

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


Danger level
Danger Level 2 - Moderate above the treeline
Danger Level 1 - Low above the treeline
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-W-NW
Wet snow above 2600m, E-SE-S-SW-W


Individual mostly small wet avalanches are possible as the day progresses.

On very steep grassy slopes individual mostly small gliding avalanches are possible. Elsewhere, avalanches can in some places be released easily, but they will be small in most cases, in particular on wind-loaded slopes. The prevalence of avalanche prone locations 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

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

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


Fresh wind slabs require caution.

In some localities increase in avalanche danger as a consequence of fresh snow and strong wind. The fresh wind slabs must be evaluated with care and prudence in particular on west to north to southeast facing aspects, in particular above the tree line. 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.

Snowpack

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

5 to 10 cm of snow. will fall. Over a wide area strong southwesterly wind. The fresh wind slabs are clearly recognisable to the trained eye. They are mostly rather small. 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 be moist below the tree line.

Tendency

Moderate, level 2.

Danger level
Danger Level 2 - Moderate
Avalanche Problem
Gliding snow above 2600m, E-SE-S-SW-W
Wind-drifted snow above 2200m, N-NE-E-SE-W-NW


Fresh wind slabs require caution.

The fresh wind slabs must be evaluated with care and prudence in particular on west to north to southeast facing aspects, in particular in gullies and bowls, and behind abrupt changes in the terrain. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. 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.

Snowpack

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

At high altitudes and in high Alpine regions the wind was strong to storm force in some cases. As the day progresses the wind slabs have increased in size moderately. The fresh wind slabs are clearly recognisable to the trained eye. They are mostly rather small but can in some cases be released easily. 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 be moist below the tree line.

Tendency

Danger level
Danger Level 1 - Low
Avalanche Problem
Wind-drifted snow above 2200m, N-NE-NW
Gliding snow above 2600m, E-SE-S-SW-W


Fresh wind slabs at high altitude. Slides can occur on steep grassy slopes.

Individual avalanche prone locations for dry avalanches are to be found in particular on very steep shady slopes above approximately 2200 m, especially adjacent to ridgelines. Such avalanche prone locations are rare and are easy to recognise. Individual gliding avalanches and moist snow slides are possible.

Snowpack

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

Over a wide area up to 5 cm of snow. will fall above approximately 1500 m. The snowpack will be in most cases stable. The snowpack will be moist over a wide area. This applies in all aspects below approximately 2000 m as well as on sunny slopes below approximately 2400 m. At low and intermediate altitudes hardly any snow is lying.

Tendency

Low, level 1.
