Loose-snow avalanches. Avalanche danger is CONSIDERABLE. Activities in backcountry make no sense except in reduced cases. Triggering a slab avalanche in very steep terrain is possible even by minimum additional loading. This applies in particular to ridgeline steep terrain in W-S-E aspects and in steep gullies. Potential slab avalanches are ordinarily medium-to-large sized. On extremely steep slopes and in rocky steep terrain, naturally triggered medium-to-large sized avalanches are possible (loose-snow avalanches with powder cloud). On previously bare ground surfaces, glide-snow avalanches are also possible. The heavy snowfall of recent days (70-120 cm of settled snow) is gradually settling under its own weight amid diffuse light in the solar radiation of March. The fresh snow is rather homogenous, sink-in depths have receded significantly. The uppermost layers of fresh snow are loosely-packed and were deposited at high altitudes as drifts near to ridgelines. Potential fracture points are most likely in the cold, uppermost layers of fresh snow. Transitions to deep snow terrain in the old snowpack are no longer likely to be triggered. On Friday, adequate visibility and initially dry weather, a few sunny phases are also possible. In the afternoon, visibility will deteriorate, snow showers will become more frequent. Winds will be light to moderate from the north. Temperature at 2000 m: -14 degrees; at 3000 m, -21 degrees. On Saturday the peaks will be shrouded in cloud, intermittent snowfall is possible. Fresh snow: 10-20 cm, very loose and cold. In the afternoon it will become drier, a bit of sunshine is possible. A moderate-to-strong wind will be blowing from northerly directions. Temperature at 2000 m: -14 degrees; at 3000 m; -21 degrees. Due to the lastest bout of fresh snow and some wind, avalanche danger above the treeline will remain CONSIDERABLE. 2021-03-18T17:00:00+00:00 avalanche-warnings.eu 2021-03-18T23:00:00+00:00 2021-03-19T23:00:00+00:00 3 2 drifting snow near ridges, often easily triggerable new snow rapidly increasing with ascending altitude, loose-snow avalanches in steep terrain Caution in steep terrain above 1900 m Avalanche danger above 1900 m is CONSIDERABLE, below that altitude MODERATE. Defensive conduct and prudently chosen tracks are advised with ascending altitude. Triggering a slab avalanche in very steep and ridgeline terrain is possible even by minimum additional loading. This applies especially to steep ridgeline terrain in W-S-E aspects and steep gullies. Potential slab avalanches are mostly medium-to-large sized. In extremely steep slopes and rocky terrain, naturally triggered small-to-medium, in isolated cases also large sized avalanches are possible (loose-snow avalanches with powder cloud). Initial isolated glide-snow avalanches are possible on slopes which were previously bare of snow. The heavy snowfall of recent days (70-120 cm of settled snow) is gradually settling under its own weight amid diffuse light in the solar radiation of March.

Winds will be light to moderate from the north. Temperature at 2000 m: -10 degrees. On Saturday the peaks will be shrouded in cloud, intermittent snowfall is possible. Fresh snow: 10-15 cm, very loose and cold. In the afternoon it will become drier, a bit of sunshine is possible. A moderate-to-strong wind will be blowing from northerly directions. Temperature at 2000 m: -14 degrees. Due to the lastest bout of fresh snow and some wind, avalanche danger above the treeline will remain CONSIDERABLE (ridgeline snowdrift problem). 2021-03-18T17:00:00+00:00 avalanche-warnings.eu 2021-03-18T23:00:00+00:00 2021-03-19T23:00:00+00:00 2 new snow increasing with ascending altitudek loose-snow avalanche in steep terrain Loose-snow avalanches in steep terrain Avalanche danger is MODERATE. Triggering a small slab avalanche is possible in very steep ridgeline terrain. This applies to steep ridgeline slopes in W-S-E aspects. On extremely steep slopes, slides of fresh snow can provoke small loose-snow avalanches. The heavy snowfall of recent days (50-70 cm of settled snow) is gradually settling under its own weight amid diffuse light in the solar radiation of March. The fresh snow is rather homogenous, sink-in depths have receded significantly. The uppermost layers of fresh snow are loosely-packed and were deposited at high altitudes as drifts near to ridgelines.

Winds will be light to moderate from the north. Temperature at 2000 m: -10 degrees. On Saturday the peaks will be shrouded in cloud, intermittent snowfall is possible. Fresh snow: 10-15 cm, very loose and cold. In the afternoon it will become drier, a bit of sunshine is possible. A moderate-to-strong wind will be blowing from northerly directions. Temperature at 2000 m: -14 degrees. On the weekend, little change. Avalanche danger remains MODERATE. Slight snowdrift problem, small loose-snow avalanches. 2021-03-18T17:00:00+00:00 avalanche-warnings.eu 2021-03-18T23:00:00+00:00 2021-03-19T23:00:00+00:00 3 gliding snow on steep grass-covered slopes which previously were bare drifting snow ridgeline, easily triggered in places Glide-snow avalanches and ridgeline snowdrifts Avalanche danger is CONSIDERABLE due to two threats: The homogenous fresh snow will lead to initial glide-snow avalanches on grassy slopes which were previously bare. These releases can become large. On very steep ridgeline slopes a slab avalanche can be triggered by minimum additional loading in isolated cases. this applies particularly to ridgeline steep slopes in W-S-NE aspects. Potential slab avalanches are generally medium-to-large. The heavy snowfall of recent days (50-70 cm of settled snow) is gradually settling under its own weight amid diffuse light in the solar radiation of March. The fresh snow is rather homogenous, sink-in depths have receded significantly. The uppermost layers of fresh snow are loosely-packed and were deposited at high altitudes as drifts near to ridgelines. Potential fracture points are most likely in the cold uppermost layers of the fresh snow and on warm ground which was previously bare of snow. On Friday, adequate visibility and initially dry weather, a few sunny phases are also possible. In the afternoon, visibility will deteriorate, snow showers will become more frequent. Winds will be light to moderate from the north. Temperature at 2000 m: -10 degrees. On Saturday the peaks will be shrouded in cloud, intermittent snowfall is possible. Fresh snow: 10-15 cm, very loose and cold. In the afternoon it will become drier, a bit of sunshine is possible. A moderate-to-strong wind will be blowing from northerly directions. Temperature at 2000 m: -14 degrees. Due to the fresh snow on Friday night, accompanied by some wind, avalanche danger will remain CONSIDERABLE (ridgeline snowdrift problem, glide-snow problem). 2021-03-18T17:00:00+00:00 avalanche-warnings.eu 2021-03-18T23:00:00+00:00 2021-03-19T23:00:00+00:00 2 1 drifting snow in gullies, mostly by large additional loading Favourable. Caution in gullies. Avalanche danger is MODERATE above 1900 m due to snowdrift masses in the gullies. These are triggerable, primarily by large additional loading (no distances maintained, a fall, etc.). Potential avalanches will be medium-sized. Avalanche prone locations are found on windblown, hard surfaces, they are easy to recognize There has been about 20-30 cm of fresh snow registered below 1900 m. Above that the terrain is windblown and hard. The most recent snowdrifts are found in gullies in all aspects. Below the treeline and in wind-protected zones, there is beautiful powder. The old snowpack beneath that is generally stable. On Friday, adequate visibility, no precipitation, some sunshine. Weak north winds. Temperature at 1500 m: -9 degrees, at 2500 m: -14 degrees. On Saturday, more cloud cover but adequate visibility. Northerly winds will intensify up to 40 km/hr. At 2500 m: -14 degrees. On the weekend, no significant change is expected. No fresh snowfall, no other influences. MODERATE avalanche danger due to old snowdrifts in gullies.
