Avalanche prone locations are found in isolated shady terrain where older snowdrifts can trigger a slab avalanche primarily by large additional loading. On sunny slopes at high altitudes, the danger of wet slab avalanches (both naturally and humanly triggered) will swiftly rise during the course of the day. In isolated cases large (magnitude 3) naturally triggered avalanches can release. At intermediate altitudes, small wet loose-snow avalanches can be expected. On shady slopes, and above 2200 m on sunny slopes, weak layers of faceted crystals and depth hoar are weakening the snowpack fundament. It is covered by older snowdrifts in some places which are poorly bonded with the base. On sunny slopes the snowpack rapidly moistens during the daytime, or becomes thoroughly wet; this destabilizes the snowpack at high altitudes and can lead to slab avalanches triggering. At intermediate altitude, the tendency is towards loose-snow avalanches, since the snowpack is so wet. Brilliant sunshine, good visibility, very warm in the heights. At 2000 m: 8-10 degrees. Light to moderate southerly wind. It will remain sunny and warm. Wet snow persists as the main avalanche problem 2021-02-20T17:00:00+00:00 avalanche-warnings.eu 2021-02-20T23:00:00+00:00 2021-02-21T23:00:00+00:00 1 wet snow strong warmth impulse Low avalanche danger but isolated danger zones in shady terrain. Wet slides on sunny slopes. Generally, low avalanche danger prevails. Only in isolaated shady spots can snowdrifts trigger small slab avalanches. On sunny slopes, small naturally triggered wet loose-snow avalanches can be expected. On shady slopes, isolated layers of faceted crystals are weakening the snowpack fundament. On sunny slopes the snowpack rapidly moistens during the daytime, or becomes throughly wet. At low altitudes there is hardly any snow on sunny slopes. Brilliant sunshine, good visibility, very warm in the heights. At 2000 m: 8-10 degrees. Light to moderate southerly wind. It will remain sunny and warm. Wet snow persists as the biggest avalanche problem.
