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


Danger level
Danger Level 3 - Considerable above 2600m
Danger Level 2 - Moderate above 2600m
Avalanche Problem
Gliding snow above 2200m, 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. Wind slabs and weakly bonded old snow require caution.

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 2200 m. As the day progresses as a consequence of warming during the day and solar radiation 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 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 2200 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.

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 2200m, N-NE-E-W-NW
Wet snow above 2600m, E-SE-S-SW-W


Fresh wind slabs require caution.

As a consequence of a moderate to strong northwesterly wind, mostly small wind slabs will form in all aspects. They can in some places be released easily. The wind slabs are to be bypassed as far as possible. As a consequence of the solar radiation, the likelihood of gliding avalanches and moist snow slides being released will increase a little.

Snowpack

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

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

Tendency

Fresh wind slabs require caution.

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


Fresh wind slabs require caution.

As a consequence of a sometimes strong wind from northwesterly directions, sometimes avalanche prone wind slabs will form in all aspects. The fresh and older wind slabs must be evaluated with care and prudence. Caution is to be exercised 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, in particular medium-sized 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

In the northwest and in the north in some regions up to 5 cm of snow. will fall. At high altitudes and in high Alpine regions the wind will be moderate to strong. As the day progresses the wind slabs will increase in size moderately. The fresh wind slabs are mostly rather small but can be released easily. 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.
