The fresh wind slabs must be evaluated with care and prudence in all aspects above the tree line. They are mostly easy to recognise but can be released easily. In the regions exposed to heavier precipitation caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. As a consequence of warming during the day and solar radiation individual gliding avalanches are possible, but they can reach medium size, especially at the base of rock walls and on steep grassy slopes below approximately 2400 m. Areas with glide cracks are to be avoided as far as possible. The wind has transported only a little snow. The fresh wind slabs are clearly recognisable to the trained eye. These are lying on soft layers in particular on shady slopes above the tree line. The older wind slabs have bonded quite well with the old snowpack. <br/> The old snowpack will be moist below the tree line. Moderate, level 2. Temporary increase in danger of gliding avalanches and snow slides as a consequence of warming during the day and solar radiation. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files_local/2019-12-04/2019-12-03_16-00-00/0db643fe-1446-4886-b1f5-2a2147703ca4.jpg website Link to region on the website https://avalanche.report/bulletin/2019-12-04?region=0db643fe-1446-4886-b1f5-2a2147703ca4 2019-12-03T16:00:00Z 2019-12-03T23:00:00Z 2019-12-04T23:00:00Z Avalanche.report https://avalanche.report Western Tuxer Alps Karwendel Mountains Eastern Tuxer Alps Central Lechtal Alps Grieskogel Mountains Western Verwall Mountains Eastern Verwall Mountains Silvretta Samnaun Mountains Eastern Lechtal Alps - Ammergau Alps Northern Oetz and Stubai Alps Mieming Mountains low low 1 2 2 low 1 1 dp6 dp2 wind_drifted_snow NW NE N 2400 gliding_snow S SW W E SE 2600 decreasing 2019-12-04T23:00:00Z 2019-12-05T23:00:00Z Wind slabs above approximately 2400 m.
