Storm winds plus fresh snow have led to snow transport. Caution urged in N/E/S aspects, where slabs can be triggered even by minimum additional loading, which in turn can sweep away deeper down layers of the snowpack. Fresh cornices are instable, can trigger. As a result of solar radiation, loose-snow avalanches can trigger naturally in steep rough and rocky terrain. From Dachstein to Hochschwab, an additional 10 cm of fresh snow was registered. The fresh snow and fresh drifts now blanket surface hoar in wind-protected zones. The old snowpack at high altitudes is often weakened by faceted crystals near melt-freeze crusts in the snowpack: these are weak layers! An intermediate high-pressure front will bring lots of sunshine and mostly cloudless skies. Quite mild. Winds will be light to moderate from the west. At 2000 m: 0 degrees. On Thursday a cold front coming from the north will bring lower temperatures, very stormy winds, and snowfall. From Dachstein to the Gesäuse and Hochschwab the snowfall will be more frequent. Further south, only a bit of snowfall. Avalanche danger will increase. 2022-01-18T17:00:00+00:00 avalanche-warnings.eu 2022-01-18T23:00:00+00:00 2022-01-19T23:00:00+00:00 1 old snow in gullies, steep bowls Caution in northern aspects: persistent weak layer Isolated danger zones on extremely steep north-facing slopes. Stormy (sometimes gale) winds will generate small snowdrift patches in eastern and southern aspects Older snowdrifts can trigger by large additional loading. The snowpack was able to settle well. The old snowpack at high altitudes is being weakened in places by faceted crystals, elsewhere the snowpack is hardened and icy. Some snowdrifts at high altitudes were deposited atop the hardened old snowpack surface or on a layer of surface hoar. An intermediate high-pressure front will bring lots of sunshine and mostly cloudless skies. Quite mild. Winds will be light to moderate from the west. At 2000 m: 0 degrees. On Thursday a cold front coming from the north will bring lower temperatures, very stormy winds, and snowfall. From Dachstein to the Gesäuse and Hochschwab the snowfall will be more frequent. Further south, only a bit of snowfall. Avalanche danger will not change significantly.
