Danger level
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW
Gliding snow above 2400m, N-NE-E-SE-S-SW-W-NW
Fresh wind slabs represent the main danger.
As a consequence of fresh snow and wind, sometimes avalanche prone wind slabs will form. Avalanches can in some cases be released by a single winter sport participant and reach large size in isolated cases. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain at high altitudes and in high Alpine regions. On wind-loaded slopes individual medium-sized and, in isolated cases, large natural avalanches are possible, in particular in the regions exposed to heavier precipitation in the Zillertal Alps, in the Rieserferner Mountains and in the Dolomites. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. They are barely recognisable because of the poor visibility.
On steep grassy slopes gliding avalanches and snow slides are possible as a consequence of the fresh snow, in the regions exposed to heavier precipitation especially at low and intermediate altitudes.
Snowpack
dp 6: cold, loose snow and wind
Faceted weak layers exist in the top section of the snowpack above approximately 2800 m.
Over a wide area 10 to 30 cm of snow, and even more in some localities, will fall above approximately 1000 m. The strong wind will transport the fresh snow significantly. Fresh wind slabs are lying on soft layers especially on steep shady slopes above approximately 2400 m.
The old snowpack will be wet all the way through at intermediate and high altitudes.
Tendency
Decrease in danger of dry avalanches. Increase in danger of moist avalanches as a consequence of solar radiation. Considerable, level 3.
