Caution: freshly generated snowdrift accumulations at high altitudes
Fresh snow and drifts are triggerable esp. on steep shady slopes. One sole skier can trigger a small-to-medium loose-snow or slab avalanche. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. On steep grass-covered slopes with sufficient snow on the ground or atop smooth ground, isolated small-to-medium glide-snow avalanches are possible. In rocky terrain, increasingly frequent slides and small loose-snow avalanches are possible.
High-altitude shady slopes have small snowdrifts atop often faceted weak soft layers, bonding is often inadequate. At night a breakable crust forms, sometimes capable of bearing loads. On steep north-facing slopes, there is still powder. The old snowpack is well consolidated. On sunny slopes and at lower altitudes the fresh snow will fall on bare ground, the snow is often moist
Clear nighttime skies and cold. On Wednesday, high-pressure front conditions will provide sunshine all day. At 2000m. 0 to +3 degrees. Light southerly winds at high altitudes.
Receding danger of dry-snow avalanches. Due to daytime warmth, increasingly frequent wet-snow avalanches.
