Fresh and somewhat older wind slabs must be evaluated with care and prudence in all aspects above approximately 2200 m. Avalanches can be released by a single winter sport participant and reach large size in isolated cases. The wind slabs are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. In isolated cases avalanches can be triggered in deep layers of the snowpack. The number and size of avalanche prone locations will increase with altitude. The current avalanche situation calls for careful route selection. In addition there is a danger of gliding avalanches. In some cases the wind slabs have bonded poorly with each other and the old snowpack. Wind slabs are clearly recognisable to the trained eye. Transitions from a shallow to a deep snowpack where weaknesses exist in the old snowpack are especially precarious. Faceted weak layers exist in the old snowpack, in particular on steep, rather lightly snow-covered east, south and west facing slopes as well as adjacent to ridgelines above approximately 2200 m. Slight decrease in danger of dry avalanches. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files_local/2019-12-31/2019-12-30_16-00-00/29614b08-d038-41df-a6dc-7b710a54fb8c.jpg website Link to region on the website https://avalanche.report/bulletin/2019-12-31?region=29614b08-d038-41df-a6dc-7b710a54fb8c 2019-12-30T16:00:00Z 2019-12-30T23:00:00Z 2019-12-31T23:00:00Z Avalanche.report https://avalanche.report Latemar Southern Adamello Primiero - Pale di S.

The fresh and somewhat older wind slabs are in many cases extensive and in some cases prone to triggering. Even single persons can release avalanches as before, in particular adjacent to ridgelines. Ski touring and other off-piste activities, including snowshoe hiking, call for experience in the assessment of avalanche danger and careful route selection, in particular on steep slopes above approximately 1800 m as well as on wind-loaded slopes. In steep terrain there is a danger of falling on the icy crust. Below approximately 2200 m small and, in isolated cases, medium-sized gliding avalanches are possible. The wind slabs have formed in particular in gullies and bowls, and behind abrupt changes in the terrain. These are in many cases extensive and in some cases prone to triggering. In some cases the various wind slabs have bonded still only poorly with each other and the old snowpack. The snowpack will be moist below approximately 2200 m. A latent danger of gliding avalanches exists, in particular at the base of rock walls below approximately 2200 m. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files_local/2019-12-31/2019-12-30_16-00-00/0e56e3b6-8d55-43e5-a3bf-814e594373b8.jpg website Link to region on the website https://avalanche.report/bulletin/2019-12-31?region=0e56e3b6-8d55-43e5-a3bf-814e594373b8 2019-12-30T16:00:00Z 2019-12-30T23:00:00Z 2019-12-31T23:00:00Z Avalanche.report https://avalanche.report Eastern Nonsberger Alps Northern Dolomites of Fiemme Prealps Cembra Valley Bondone and Stivo Vallarsa Western Nonsberg Alps Folgaria - Laverone Ledro Valley Marzola - Valsugana moderate moderate 2 2 2 low 1 1 wind_drifted_snow N SW NE E S NW SE W treeline gliding_snow N SW NE E S NW SE W 1800 2200 decreasing 2019-12-31T23:00:00Z 2020-01-01T23:00:00Z The fresh and somewhat older wind slabs must be evaluated with care and prudence in all aspects.
