Avalanche danger in the regions Dachstein, Totes Gebirge, northern Niedere Tauern as far as the Ennstal Alps is Considerable above the timberline. Avalanche prone locations are located in eastern and northern aspects. Older snowdrift accumulations and freshly generated drifts can be triggered even by minimum additional loading. A slab can fracture down to more deeply embedded layers in the snowpack. Rising temperatures over the last 24 hours have generally had a positive effect on the snowpack, which was able to settle somewhat. At high altitudes in northern and eastern aspects, older snowdrift masses lie deposited on top of a soft layer of snow. On Friday night in the northern barrier cloud zones, surface hoar formed. The forecast fresh snow and snowdrifts will be deposited on top of the just formed surface hoar. Bonding will be inadequate. At intermediate and low altitudes the snow cover has settled. In some places a crust formed, which is not capable of bearing loads. On Sunday it will turn wintery. Snowfall is expected over widespread areas, and a cold northerly wind will be blowing. In the northern barrier zones 20-30 cm of fresh snow is anticipated. Visibility will be severely reduced. Compared to Saturday, it will turn measurably colder, at 2000 m, -8 degrees. The danger of slab avalanches will remain upright 2021-12-04T17:00:00+00:00 avalanche-warnings.eu 2021-12-04T23:00:00+00:00 2021-12-05T23:00:00+00:00 2 1 drifting snow behind abrupt changes in terrain Northerly winds! Freshly generated snowdrifts! Avalanche prone locations are found on east-facing and south-facing slopes. Older snowdrift accumulations and freshly generated drifts can be triggered even by minimum additional loading. Generally, Size-2 avalanches are anticipated. Rising temperatures over the last 24 hours have generally had a positive effect on the snowpack, which was able to settle somewhat. At high altitudes in northern and eastern aspects, older snowdrift masses lie deposited on top of a soft layer of snow. On Friday night in the northern barrier cloud zones, surface hoar formed. The forecast fresh snow and snowdrifts will accordingly be deposited on top of the just formed surface hoar. Bonding will be inadequate. On Sunday it will turn wintery. Snowfall is expected over widespread areas, and a cold northerly wind will be blowing. In the northern barrier zones 20-30 cm of fresh snow is anticipated. Visibility will be severely reduced. Compared to Saturday, it will turn measurably colder, at 2000 m, -8 degrees. No significant change in avalanche danger levels is anticipated. 2021-12-04T17:00:00+00:00 avalanche-warnings.eu 2021-12-04T23:00:00+00:00 2021-12-05T23:00:00+00:00 1 drifting snow behind abrupt changes in terrain Fresh snowdrifts! Avalanche danger is low. As a result of approaching snowfall, isolated danger zones will be generated on east-facing and south-facing slopes, particularly perilous are the ridgeline zones. The snowfall of this last week was deposited on top of moist ground. There is 15-25 cm of snow on the ground. At low altitudes it has already become green again. On Sunday it will turn wintery. Snowfall is expected over widespread areas, and a cold northerly wind will be blowing. Visibility will be severely reduced. Compared to Saturday, it will turn measurably colder, at 2000 m, -8 degrees. No significant change in avalanche danger levels is anticipated. 2021-12-04T17:00:00+00:00 avalanche-warnings.eu 2021-12-04T23:00:00+00:00 2021-12-05T23:00:00+00:00 2 1 drifting snow near ridgelines Fresh snowdrifts! Avalanche danger between Turrach and Koralpe is moderate above the timberline. Isolated avalanche prone locations are to be found on east-facing slopes, where a slab avalanche cannot be ruled out. At the start of the season there has been up to 60 cm of snowfall registered. The snowpack has now settled. On the Koralpe and near the Zirbitzkogel, winds have blown the ridges completely bare of snow. Snowdrifts are found on east-facing slopes. On Sunday it will turn wintery. Snowfall is expected over widespread areas, and a cold northerly wind will be blowing. Visibility will be severely reduced. Compared to Saturday, it will turn measurably colder, at 2000 m, -8 degrees. Danger of slab avalanches is expected to increase slightly.
