As a consequence of a sometimes strong wind, wind slabs formed in the last few days in particular above approximately 2200 m. At elevated altitudes the avalanche prone locations are more prevalent and larger. The snowpack will be subject to considerable local variations. The mostly small wind slabs have bonded quite well with the old snowpack. The fresh and older wind slabs of the last few days are clearly recognisable. 2018-12-15T16:36:15Z Avalanche Warning Service Tyrol Norbert Lanzanasto 2018-12-15T23:00:00Z 2018-12-16T23:00:00Z 2 1 DP6 DP1 drifting snow old snow 2300 2800 Fresh wind slabs are to be evaluated with care and prudence. In the regions of the south that are exposed to the foehn wind the avalanche prone locations are more prevalent. Weakly bonded old snow above approximately 2300 m. The northerly wind will transport the fresh snow. This applies in particular along the border with South Tyrol. The fresh wind slabs are mostly easy to recognise but can be released easily. At high altitudes and in high Alpine regions and along the border with South Tyrol avalanche prone locations are more prevalent and exist in all aspects. Caution is to be exercised in particular adjacent to ridgelines. Also places where surface hoar has been covered with snow are critical, especially in areas close to the tree line,, also below the tree line, in particular west of the Sill. Weak layers in the lower part of the snowpack can still be released in some places by individual winter sport participants in particular on very steep shady slopes. This applies in particular between approximately 2300 and 2800 m. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger. The fresh snow of Sunday will be deposited on surface hoar in some places in areas close to the tree line. Soft weak layers exist in the top section of the snowpack. As a consequence of a moderate to strong northerly wind, avalanche prone wind slabs will form on Sunday in particular adjacent to ridgelines as well as at high altitudes and in high Alpine regions. In some cases the wind slabs have bonded poorly together. Faceted weak layers exist in the old snowpack on very steep shady slopes, in particular between approximately 2300 and 2800 m. Isolated whumpfing sounds serve as an alarm indicating the danger. The snowpack will be subject to considerable local variations. 2018-12-15T16:36:15Z Avalanche Warning Service Tyrol Norbert Lanzanasto 2018-12-15T23:00:00Z 2018-12-16T23:00:00Z 1 1 DP6 drifting snow Low danger will prevail. Fresh wind slabs represent the main danger. The somewhat older wind slabs of last week are now only very rarely prone to triggering. The avalanche prone locations are rare. This applies adjacent to ridgelines above the tree line as well as on very steep shady slopes. Below the tree line from a snow sport perspective, in most cases insufficient snow is lying. The snowpack will be in most cases favourable. Further decrease in avalanche danger. 2018-12-15T16:00:00Z Avalanche Warning Service Trentino Walter Beozzo 2018-12-15T23:00:00Z 2018-12-16T23:00:00Z 2 1 drifting snow The danger exists in particular in alpine snow sports terrain. The sometimes avalanche-prone wind slabs of the last few days represent the main danger. They are to be found in particular adjacent to ridgelines in all aspects and in the high Alpine regions. Wind slabs can be released, in particular by large loads and reach medium size. These avalanche prone locations are to be found in particular on steep slopes above approximately 2200 m, and adjacent to ridgelines and in gullies and bowls in all aspects. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. Also in the regions of the north that are exposed to the foehn wind a little fresh snow. The wind has transported the fresh snow and, in some cases, old snow as well. The snowpack remains prone to triggering especially on wind-loaded slopes. 2018-12-15T16:00:00Z Avalanche Warning Service Trentino Walter Beozzo 2018-12-15T23:00:00Z 2018-12-16T23:00:00Z 1 drifting snow Only a little snow is lying. The avalanche prone locations are rare and are clearly recognisable to the trained eye. Individual avalanche prone locations are to be found in extremely steep terrain. Even a small avalanche can sweep snow sport participants along and give rise to falls. Above the tree line from a snow sport perspective, in most cases insufficient snow is lying. 2018-12-15T16:36:15Z Avalanche Warning Service Tyrol Norbert Lanzanasto 2018-12-15T23:00:00Z 2018-12-16T23:00:00Z 1 1 DP6 drifting snow Fresh wind slabs require caution. This applies in particular adjacent to ridgelines. Wind slabs are in many cases small. At elevated altitudes the avalanche prone locations are more prevalent and larger. They are clearly recognisable to the trained eye. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. The snowpack will be subject to considerable local variations. The mostly small wind slabs have bonded quite well with the old snowpack. From a snow sport perspective, in most cases insufficient snow is lying. 2018-12-15T16:33:33Z Avalanche Warning Service Tyrol Norbert Lanzanasto 2018-12-15T23:00:00Z 2018-12-16T23:00:00Z 2 1 DP6 drifting snow Wind slabs require caution. As a consequence of a sometimes strong wind, sometimes avalanche prone wind slabs formed in the last few days in particular above approximately 2200 m. At elevated altitudes the avalanche prone locations are more prevalent and larger. In particular in the north and in the west avalanche prone locations are more prevalent and the danger is greater. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. The snowpack will be subject to considerable local variations. The mostly small wind slabs have bonded quite well with the old snowpack. The fresh and older wind slabs of the last few days are clearly recognisable. From a snow sport perspective, in most cases insufficient snow is lying. Further decrease in danger. 2018-12-15T16:33:33Z Avalanche Warning Service Tyrol Norbert Lanzanasto 2018-12-15T23:00:00Z 2018-12-16T23:00:00Z 1 drifting snow Only a little snow is lying.

The wind slabs must be evaluated with care and prudence in particular on west to north to east facing aspects above approximately 2200 m. The wind slabs are to be found in particular adjacent to ridgelines and in gullies and bowls. In particular on wind-loaded slopes medium-sized and, in isolated cases, large avalanches are possible. In the west and in the north avalanche prone locations are more prevalent and the danger is greater. Avalanches can be released in the old snowpack in isolated cases. Backcountry touring calls for experience in the assessment of avalanche danger. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. The avalanche prone locations are sometimes covered with fresh snow and are barely recognisable because of the poor visibility. The snowpack will be subject to considerable local variations. Faceted weak layers exist in the old snowpack on steep shady slopes. Whumpfing sounds can indicate the danger. At low and intermediate altitudes thus far only a little snow is lying. In particular in the west some fresh snow. 2018-12-15T16:00:00Z Avalanche Warning Service Trentino Walter Beozzo 2018-12-15T23:00:00Z 2018-12-16T23:00:00Z 2 1 drifting snow Wind slabs require caution. As a consequence of a moderate wind, mostly shallow wind slabs formed in the last few days in particular above approximately 2200 m. At elevated altitudes the avalanche prone locations are more prevalent and larger. In particular in the north avalanche prone locations are more prevalent and the danger is greater. These avalanche prone locations are rather rare and are clearly recognisable to the trained eye. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. The snowpack will be subject to considerable local variations. The mostly small wind slabs have bonded quite well with the old snowpack.

This applies in particular adjacent to ridgelines and in pass areas in the regions of the south that are exposed to the foehn wind. Gliding avalanches and snow slides below approximately 2400 m. Fresh wind slabs represent the main danger. This applies, in particular in the regions of the south that are exposed to the foehn wind. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls above approximately 2200 m, in particular on very steep shady slopes. The fresh snow of Sunday will be deposited on surface hoar in some places at low and intermediate altitudes. The small wind slabs can be released easily by a single winter sport participant in all aspects at low and intermediate altitudes. The older wind slabs of the last few days have bonded well with the old snowpack. The wind slabs are clearly recognisable. Avalanche prone locations for gliding avalanches are to be found on steep grassy slopes below approximately 2400 m. The fresh wind slabs are lying on soft layers in particular on steep shady slopes above approximately 2200 m. The somewhat older wind slabs have bonded quite well with the old snowpack. The old snowpack will be in most cases favourable. The fresh snow of Sunday will be deposited on surface hoar in some places in all aspects in areas close to the tree line,, also below the tree line.
