On shady slopes, persistent danger due to high-altitude snowdrifts
Avalanche prone locations are found mainly on shady slopes above 1700 m where large additional loading can trigger a slab avalanche in the snowdrift accumulations. At low altitudes on very steep grass-covered slopes, naturally triggered small-to-medium glide-snow avalanches can release.
Storm-strength winds in the last few days have blown ridges and summits bare of snow and filled leeward slopes with drifts. On shady slopes the snowdrifts are often insufficiently bonded with the snow base, making them instable. Below about 1800 m the higher temperatures have stabilized the snowpack somewhat. On steep grass-covered slopes at low altitudes the snowpack is gliding increasingly.
On Tuesday, more sunshine is expected, visibility will be predominantly good. In the afternoon, increasing cloud will move in, visibility will be limited in the eastern rimline regions. Winds will be brisk from the northwest, temperatures are not expected to change much: about +1 degree at 2000 m.
Avalanche danger is expected to incrementally recede.
