Lechquellen Mountains

Freshly generated snowdrifts prone to triggering

Pure sunshine and cloudless skies in the mountains. Winds will remain unpleasantly brisk, especially in exposed ridgeline terrain, thus sharpening the temperatures. Temperature at 2000m: -5 to +1 degree; at 3000m: to -8 degrees. Moderate to brisk easterly winds at high altitudes.

Avalanche danger is not expected to change significantly. Beware freshly generated snowdrift accumulations.

Freshly generated snowdrifts prone to triggering

Fresh snowdrifts are prone to triggering, can be triggered even by minimum additional loading as slab avalanches. Danger zones occur primarily in steep ridgeline terrain and in wind-loaded gullies and bowls. Frequency and spread of avalanche prone locations increase with ascending altitude. If avalanches on high-altitude shady slopes fracture down to deeper weak layers, they can in isolated cases then grow to large size. Such avalanche prone locations occur primarily in spots where the snow is shallow or in transitions from shallow to deep snow.

The fresh snow from the weekend has already bonded well with the widespread melt-freeze crust. Surface hoar has frequently been blanketed by fresh snow on steep shady slopes. Fresh small-to-medium sized snowdrifts have been generated near ridgelines. The mid-level part of the snowpack consists of well-settled, compact layers widespread which on high-altitude shady slopes cover a poorly structured old snowpack fundament.
