As a consequence of new snow and a strong wind from northerly directions, sometimes large wind slabs formed in particular above the tree line. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in all aspects. Mostly avalanches are medium-sized but in many cases easily released. The number and size of avalanche prone locations will increase with altitude. As a consequence of solar radiation natural avalanches are possible as the day progresses, especially on extremely steep sunny slopes. <br/> On cut slopes and on steep grassy slopes individual gliding avalanches and snow slides are possible. <br/> Backcountry touring calls for experience in the assessment of avalanche danger and careful route selection. In particular in the southeast 15 to 30 cm of snow, and up to 40 cm in some localities, has fallen since Sunday above approximately 1600 m. Wind slabs are bonding only slowly with the old snowpack in all aspects, especially adjacent to ridgelines at high altitudes and in high Alpine regions. <br/> The old snowpack will be in most cases well bonded. Faceted weak layers exist in the snowpack in particular on shady slopes. Gradual decrease in avalanche danger as a consequence of the ceasing of precipitation. Wind slabs are to be evaluated with care and prudence. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2021-04-13/2021-04-12_15-00-00/35f460d1-b391-4cd1-908f-fd77c9e2440c.jpg website Link to region on the website https://avalanche.report/bulletin/2021-04-13?region=35f460d1-b391-4cd1-908f-fd77c9e2440c 2021-04-12T15:00:00Z 2021-04-12T22:00:00Z 2021-04-13T22:00:00Z Avalanche.report https://avalanche.report Western Lechtal Alps Central Lechtal Alps Glockturm Range Val Müstair Alps Western Verwall Mountains Langtaufers Eastern Verwall Mountains Allgäu Alps Silvretta Samnaun Mountains Eastern Lechtal Alps - Ammergau Alps Mieming Mountains moderate treeline no_rating no_rating low treeline no_rating no_rating dp6 dp4 wind_drifted_snow W N SW NW SE E NE S treeline moderate moderate 2 3 2 steady 2021-04-13T22:00:00Z 2021-04-14T22:00:00Z Wind slabs are to be evaluated with care and prudence.
