Fresh snowdriftrs. Isolated danger zones in gullies and bowls.
Fresh snowdrift accumulations are mostly small, triggerable only in isolated cases, esp. on wind-protected shady slopes at high altitude. Caution urged in transitions into gullies and bowls. These danger zones occur seldom.
Snowpack
resh snow (10-15cm) was registered. Freshly generated snowdrift accumulations have been deposited on top of an unfavorable old snowpack surface. Solar radiation will lead starting at midday to a moistening of the snowpack on very steep sunny slopes.
Due to fresh snow and moderate northerly winds, often trigger-sensitive snowdrift accumulations have been generated in ridgeline terrain, gullies and bowls and behind protruberances in the landscape. These drifts can be triggered in many cases by one sole skier ib NW/N/SE facing slopes above 1800m. In addition, isolated avalanches can trigger in the weak old snow, esp. on W/N/E facing slopes above 2200m. Caution urged in transitions from shallow to deep snow, e.g. at entry points into gullies and bowls. Caution in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls. Avalanches can reach medium size.
Snowpack
dp.6: cold, loose snow and wind dp.4: cold following warm / warm following cold
Since Friday there has been 15-30cm of fresh snow registeres, locally more. Winds have transported the fresh fallen snow. The fresh snowdrift accumulations lie deposited atop an unfavorable old snowpack surface, in the lower part of the snowpack (esp. on W/N/E facing slopes) are faceted, expansively metamorphosed weak layers. Very steep south-facing slopes: due to lower temperatures and low air moisture, a crust will form on the surface during the night. Weather conditions will lead to a moistening of the snowpack as of midday.
Tendency
Fresh snowdrifts need to be cautiously assessed. Pay attention to weak layers in old snowpack.

Main danger: freshly generated snowdrift accumulations
Due to fresh snow and northerly winds, often trigger-sensitive snowdrift accumulations have been generated in ridgeline terrain, gullies and bowls. These drifts can be triggered in many cases by one sole skier in all aspects above 1800m on N/NW/E facing slopes. Danger zones are easily recognized to the practiced eye. Avalanches can reach medium size.
Snowpack
dp.6: cold, loose snow and wind dp.4: cold following warm / warm following cold
Since Friday there has been up to 30cm of fresh snow registered on the Italian and Slovenian borders. The fresh snowdrift accumulations lie deposited atop an unfavorable old snowpack surface. Very steep south-facing slopes: due to lower temperatures and low air moisture, a crust will form on the surface during the night.
