Danger zones are freshly generated snowdrift accumulations on E/S/W facing slopes where slabs can often be triggered by the weight of one person. Particularly ridgeline slopes, protruberances and entries into gullies and bowls need to be assessed critically. In addition, on north-facing slopes in shady high-altitude terrain, isolated older snowdrifts can be triggered as slabs, particularly in transitions from shallow to deep snow - avoid them! In the Northern Alps there was up to 50 cm of fresh snow registered, accompanied by strong northerly winds. In the southern sectors there have been fresh snowdrifts accumulated. The fresh snow and drifts were deposited atop a melt-freeze encrusted old snowpack or atop older snowdrifts. The new snowdrift masses are prone to triggering and can also contain weak layers. In transitions to the old snow, weak layers can be formed (cold on warm). In shady high altitude terrain, faceted crystals are weakening the fundament (persistent weak layer). On sunny slopes and at low altitudes the snowpack fundament is largely stable. Monday will be variably cloudy, the sun often impeded by low lying clouds, visibility frequently reduced. In northeastern regions in the morning, light snowfall is possible. Winds will shift to northeasterly, bring still colder air masses our way. Temperatures will drop: at 2000 m to -12 degrees. Strong winds will sharpen the cold, but slacken off starting at midday. High-pressure front conditions on Tuesday will bring brilliantly sunny weather. The snowdrift problem will slowly recede. 2022-02-27T17:00:00+00:00 avalanche-warnings.eu 2022-02-27T23:00:00+00:00 2022-02-28T23:00:00+00:00 1 drifting snow thin, small snowdrift accumulations Low avalanche danger but isolated danger zones due to fresh snowdrift patches Avalanche danger is low. Nevertheless, since Saturday there have been small snowdrift accumulations freshly generated on E/S/W facing slopes which in isolated cases can trigger small slab avalanches. Danger zones occur behind protruberances and at entries into steep slopes, gullies, bowls. The shift from higher to lower temperatures has stabilized the snowpack. The surface is melt-freeze encrusted, on shady slopes there is pressed powder. Saturday brought a bit of fresh snow and new snowdrift accumulations. Bonding of old snow is generally good, but prone to triggering in isolated cases. Monday will be variably cloudy, the sun often impeded by low lying clouds, visibility frequently reduced. In northeastern regions in the morning, light snowfall is possible. Winds will shift to northeasterly, bring still colder air masses our way. Temperatures will drop: at 2000 m to -12 degrees. Strong winds will sharpen the cold, but slacken off starting at midday. High-pressure front conditions on Tuesday will bring brilliantly sunny weather. Avalanche danger will remain low.
