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.

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

Moderate, level 2.
