Weak layers in the old snowpack necessitate caution. As a consequence of fresh snow and a strong to storm force northwesterly wind, precarious wind slabs will form on Sunday in particular in gullies and bowls and behind abrupt changes in the terrain. The fresh wind slabs are mostly small but prone to triggering. In regions exposed to heavier precipitation and in high Alpine regions avalanche prone locations are more prevalent and the danger is greater. In addition the somewhat older wind slabs adjacent to ridgelines on north facing slopes are capable of being triggered in some cases still. Weakly bonded old snow: This applies above approximately 2200 m and below approximately 2700 m. Avalanches can in some places be released by a single winter sport participant and reach medium size. The avalanche prone locations are to be found on steep slopes of all aspects. Especially transitions from a shallow to a deep snowpack are unfavourable. Backcountry touring and other off-piste activities call for experience and a certain restraint. In particular from the Southern Stubai Alps via the Ahrntal to the Deferegger Alps in some localities up to 15 cm of snow. will fall. The fresh wind slabs are lying on weak layers. The somewhat older wind slabs have settled a little. Avalanche prone weak layers exist in the centre of the snowpack, in particular between approximately 2200 and 2700 m. This applies in all aspects. The snowpack will be subject to considerable local variations. As a consequence of fresh snow and strong wind there will be an increase in the avalanche danger. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-30/2018-12-29_16-00-00/f56615d5-9135-40fd-933c-502436dc6692.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-30?region=f56615d5-9135-40fd-933c-502436dc6692 2018-12-29T16:00:00Z 2018-12-29T23:00:00Z 2018-12-30T23:00:00Z Avalanche.report https://avalanche.report Southern Adamello Primiero - Pale di S.

As a consequence of wind from northwesterly directions, mostly small wind slabs will form in particular adjacent to ridgelines and in gullies and bowls. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent and the danger is greater. These avalanche prone locations are clearly recognisable to the trained eye. Avalanches can in isolated cases be released in the old snowpack and reach dangerously large size. 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. Maintaining distances between individuals is recommended. The snowpack will be subject to considerable local variations. The somewhat older wind slabs have settled a little. In steep terrain there is a danger of falling on the hard crust. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-30/2018-12-29_16-00-00/4704305a-c7a3-45b5-a5f6-06a0391ed763.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-30?region=4704305a-c7a3-45b5-a5f6-06a0391ed763 2018-12-29T16:00:00Z 2018-12-29T23:00:00Z 2018-12-30T23:00:00Z Avalanche.report https://avalanche.report Sarntal Alps Ortler Range Ulten Valley moderate moderate 2 2 2 low 1 1 wind_drifted_snow SE E S NW NE W SW N 2300 persistent_weak_layers E NW NE W N 2300 increasing 2018-12-30T23:00:00Z 2018-12-31T23:00:00Z The fresh wind slabs represent the main danger.

Hardly any increase in avalanche danger as a consequence of fresh snow and strong wind. The fresh and somewhat older wind slabs represent the main danger. The wind slabs are to be found in particular adjacent to ridgelines and in gullies and bowls as well as in the high Alpine regions. The avalanche prone locations are rather rare and are easy to recognise. Restraint should be exercised because avalanches can sweep people along and give rise to falls. Some snow will fall in some localities. From a snow sport perspective, in most cases insufficient snow is lying.
