The wet-snow problem dominates. Small-to-medium wet-snow avalanches are possible wherever there is sufficient snow. Even isolated glide-snow avalanches can release where none have yet discharged. The snowpack is thoroughly moist to wet. On Thursday, visibility will be reduced due to clouds and fog. Intermittent rainfall. Brisk westerly winds. At 2000 m: +2 degrees. On Thursday night the skies will clear. On Friday, good visibility. Sunshine. At 2000 m: +7 degrees. Springtime conditions at the end of December. 2021-12-29T17:00:00+00:00 avalanche-warnings.eu 2021-12-29T23:00:00+00:00 2021-12-30T23:00:00+00:00 3 2 wet snow heavy rain and wet snowpack Wet-snow avalanches in all aspects Avalanche danger above 1500 m is CONSIDERABLE, below that altitude danger is MODERATE. Wet-snow avalanches can release in all aspects, most small-to-medium, isolated large-sized avalanches, most between 1500 and 2400 m. Apart from wet loose-snow avalanches and isolated wet-slabs, glide-snow avalanches also have to be expected. As of about 2500 m, new snow and storm winds will generate fresh drifts which can often be triggered by minimum additional loading. On the compact old snowpack with melt-freeze crusts, 10-30 cm of moist-to-wet snow has been deposited. As of about 2500 m there is also dry snow (mostly windblown). On Thursday, visibility will be reduced due to clouds and fog. Intermittent rainfall. Strong-to-stormy W/NW winds. At 2000 m: +2 degrees. On Thursday night the skies will clear. On Friday, good visibility. Sunshine. The strong winds will recede. At 2000 m: +7 degrees. Springtime conditions at the end of December. 2021-12-29T17:00:00+00:00 avalanche-warnings.eu 2021-12-29T23:00:00+00:00 2021-12-30T23:00:00+00:00 3 2 wet snow due to rainfall drifting snow faceted-crystal base as of about 2400 m Also: considerable snowdrift problem at high altitude Avalanche danger above 1500 m is CONSIDERABLE, below that altitude danger is MODERATE. Wet-snow avalanches can release in all aspects, most small-to-medium, isolated large-sized avalanches, most between 1500 and 2400 m. As of about 2400 m, new snow and storm winds will generate fresh drifts which can often be triggered by minimum additional loading. Naturally triggered dry slabs are possible on heavily wind-loaded high altitude slopes. Atop a melt-freeze crust or a rain-ice layer (often with faceted crystals beneath) there is 10-40 cm of new snow. Up to about 2400 m the upper layer is moist-to-wet. On top of that: dry, often wind-impacted snow. The old snowpack is quite compact for the most part. On Thursday, visibility will be reduced due to clouds and fog. Intermittent rainfall to far over 2000 m. Strong-to-stormy W/NW winds. At 2000 m: +2 degrees. On Thursday night the skies will clear. On Friday, good visibility. Sunshine. The strong winds will recede. At 2000 m: +8 degrees, at 3000 m +2 degrees.. Springtime conditions at the end of December. 2021-12-29T17:00:00+00:00 avalanche-warnings.eu 2021-12-29T23:00:00+00:00 2021-12-30T23:00:00+00:00 2 wet snow due to rain drifting snow thin, small snowdrift accumulations Wet-snow avalanches Avalanche danger above 1500 m is MODERATE. Wet-snow avalanches (loose snow and slabs) can release in all aspects up to 2200 m. As of about 2200 m, moderate snowdrift problem. The drifts are mostly shallow but can often trigger even by the weight of one sole person. Atop a compact old snowpack there is 10-20 cm of moist snow. As of 2200 m the snow can be dry, but is starkly wind-impacted. On Thursday, visibility will be reduced due to clouds and fog. Intermittent rainfall. Brisk westerly winds. At 2000 m: +2 degrees. On Thursday night the skies will clear. On Friday, good visibility. Sunshine. The strong winds will recede. At 2000 m: +7 degrees. Springtime conditions at the end of December. 2021-12-29T17:00:00+00:00 avalanche-warnings.eu 2021-12-29T23:00:00+00:00 2021-12-30T23:00:00+00:00 1 favourable situation Hardened surfaces dominate Avalanche danger is low. Isolated wet-snow slides and isolated glide-snow avalanches are possible. Compact snowpack melt-freeze encrusted On Thursday, very windy, the NW winds will intermittently disperse the clouds, visibility will vary. At 2000 m: +2 degrees. On Thursday night the skies will clear. On Friday, good visibility. Sunshine. The strong winds will recede. At 2000 m: +8 degrees. Springtime conditions at the end of December.
