In addition in all aspects, an increasing number of medium-sized and, in many cases, large natural dry avalanches are to be expected. In the regions exposed to a lot of wind this applies in particular on steep slopes, also below the tree line. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Extensive experience in the assessment of avalanche danger and great restraint are required. The danger exists in particular in alpine snow sports terrain.Over a wide area 25 to 30 cm of snow, and up to 50 cm in some localities, fell on Monday. Some snow will fall on Tuesday in some localities. As a consequence of a strong wind from southwesterly directions, avalanche prone wind slabs will form in all aspects. Over a wide area wind slabs are lying on soft layers, this also applies below the tree line. The fresh wind slabs are lying on surface hoar in some places in areas close to the tree line. The old snowpack is largely stable.Outside marked and open pistes a precarious avalanche situation will prevail. Fresh wind slabs are to be avoided.dangerRatingMapSimplified danger rating map of the regionhttps://avalanche.report/albina_files/2020-12-29/2020-12-28_16-00-00/85b6414e-624f-48f3-95be-a7ddd8f09204.jpgwebsiteLink to region on the websitehttps://avalanche.report/bulletin/2020-12-29?region=85b6414e-624f-48f3-95be-a7ddd8f092042020-12-28T16:00:00Z2020-12-28T23:00:00Z2020-12-29T23:00:00ZSexten DolomitesLatemarSouthern Stubai AlpsTexel MountainsSouthern AdamelloSarntal AlpsAdamello - PresanellaNorthern Brenta - PellerBondone and StivoFolgaria - LaveroneSouthern BrentaSouthern LagoraiNorthern LagoraiMaddalenePine' - Mocheni ValleyUlten ValleyEastern Nonsberger AlpsNorthern Dolomites of FiemmeGröden DolomitesPrimiero - Pale di S.

The fresh and somewhat older wind slabs can be released easily. or in isolated cases naturally, in all aspects, caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Mostly the avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude. <br/> Weak layers in the lower part of the snowpack can still be released in isolated cases by individual winter sport participants. Caution is to be exercised in particular on steep shady slopes above approximately 2200 m, especially in areas where the snow cover is rather shallow, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.5 to 15 cm of snow, and even more in some localities, fell on Monday. The strong wind will transport the fresh and old snow. In many cases wind slabs are lying on soft layers, also below the tree line. The wind slabs will be deposited on surface hoar in some places in areas close to the tree line. <br/> Steep shady slopes: The old snowpack will be prone to triggering in some places. Towards its base, the snowpack is faceted and weak. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack.Fresh wind slabs are to be evaluated with care and prudence.dangerRatingMapSimplified danger rating map of the regionhttps://avalanche.report/albina_files/2020-12-29/2020-12-28_16-00-00/4acae89d-c052-48fa-a09b-1b4a9d496b09.jpgwebsiteLink to region on the websitehttps://avalanche.report/bulletin/2020-12-29?region=4acae89d-c052-48fa-a09b-1b4a9d496b092020-12-28T16:00:00Z2020-12-28T23:00:00Z2020-12-29T23:00:00ZBrandenberg AlpsWestern Kitzbühel AlpsWilder Kaiser Mountains - Waidring AlpsEastern Kitzbühel Alpsmoderatetreelineno_ratingno_ratinglowtreelineno_ratingno_ratingdp6wind_drifted_snowNNWNEtreelinemoderatemoderate232steady2020-12-29T23:00:00Z2020-12-30T23:00:00ZWind slabs are to be evaluated with care and prudence.The fresh and somewhat older wind slabs are in some cases prone to triggering above the tree line, especially adjacent to ridgelines and in gullies and bowls.
