Individual avalanche prone locations for dry avalanches are to be found in particular on northwest, north and northeast facing slopes. Caution is to be exercised in particular in extremely steep terrain on little-used, rather lightly snow-covered slopes at high altitudes and in high Alpine regions. These avalanche prone locations are rather rare. <br/> <br/> As the temperature drops there will be an additional decrease in the danger of wet and gliding avalanches on Sunday. In particular on sunny slopes only isolated small to medium-sized natural wet avalanches are possible below approximately 2400 m. <br/> <br/> Moist and wet avalanches can additionally in very isolated cases be released in near-surface layers, in particular by large additional loads.Outgoing longwave radiation during the night will be reduced. For this reason the snowpack is frozen with a strong crust only at high altitudes. <br/> <br/> Older wind slabs are lying on soft layers, especially on little used slopes, as well as adjacent to ridgelines at high altitudes and in high Alpine regions.Further decrease in danger of wet and gliding avalanches as the temperature drops.dangerRatingMapSimplified danger rating map of the regionhttps://avalanche.report/albina_files/2021-04-04/2021-04-03_15-00-00/994bc021-141c-4d07-a066-e9b0b927314a.jpgwebsiteLink to region on the websitehttps://avalanche.report/bulletin/2021-04-04?region=994bc021-141c-4d07-a066-e9b0b927314a2021-04-03T15:00:00Z2021-04-03T22:00:00Z2021-04-04T22:00:00ZWestern Verwall MountainsEastern Verwall MountainsAllgäu AlpsEastern Lechtal Alps - Ammergau AlpsNorthern Oetz and Stubai AlpsMieming MountainsWestern Tuxer AlpsKarwendel MountainsEastern Tuxer AlpsBrandenberg AlpsWestern Kitzbühel AlpsWilder Kaiser Mountains - Waidring AlpsEastern Kitzbühel AlpsWestern Lechtal AlpsCentral Lechtal AlpsGrieskogel Mountainsmoderate2000no_ratingno_ratingmoderate2000no_ratingno_ratingdp7dp10wind_drifted_snowNNWNE2000moderatemoderate222wet_snowWSWSEES2000moderatemoderate222steady2021-04-04T22:00:00Z2021-04-05T22:00:00ZFurther decrease in danger of moist and wet avalanches as the temperature drops.As the temperature drops only isolated natural wet avalanches are possible, but they will be mostly small. <br/> Wet avalanches can in some cases release deeper layers of the snowpack and reach medium size in isolated cases especially on very steep sunny slopes. <br/> <br/> Moist and wet avalanches can additionally in isolated cases be released in near-surface layers by a single winter sport participant. These avalanche prone locations are rather rare. They are to be found especially on very steep sunny slopes below approximately 2200 m. <br/> <br/> <br/> Dry avalanches can in very isolated cases be released in the weakly bonded old snow. Caution is to be exercised in particular in extremely steep terrain on little-used, rather lightly snow-covered slopes at high altitudes and in high Alpine regions, this also applies adjacent to ridgelines. Sometimes the avalanches are medium-sized. <br/> <br/> Areas with glide cracks are to be avoided as far as possible.Outgoing longwave radiation during the night will be barely evident. <br/> <br/> At low and intermediate altitudes and on sunny slopes the snowpack is moist. <br/> <br/> Faceted weak layers exist in the snowpack in particular on steep shady slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and stability tests indicate the existence of a weak snowack especially on wind-loaded slopes.Further decrease in danger of wet and gliding avalanches as the temperature drops.dangerRatingMapSimplified danger rating map of the regionhttps://avalanche.report/albina_files/2021-04-04/2021-04-03_15-00-00/042e0bb7-9dcc-4831-83f5-4db5d48785bd.jpgwebsiteLink to region on the websitehttps://avalanche.report/bulletin/2021-04-04?region=042e0bb7-9dcc-4831-83f5-4db5d48785bd2021-04-03T15:00:00Z2021-04-03T22:00:00Z2021-04-04T22:00:00ZDurreck RangeVenediger RangeSouthern Zillertal Alps and High Tauernlow2400no_ratingno_ratingmoderate2400no_ratingno_ratingdp10persistent_weak_layersNNWNE2400lowlow132wet_snowWSWSEES2400moderatemoderate232steady2021-04-04T22:00:00Z2021-04-05T22:00:00ZIncrease in danger of wet avalanches in the course of the day.The early morning will see quite favourable conditions over a wide area.
