Lechquellen Mountains

Main danger: weak old snowpack layers. Also fresh snowdrifts require caution.

Main danger: weak old snowpack layers. Also fresh snowdrifts require caution.

It is possible to trigger slab avalanches in the old snow particularly by large additional loading. If a release sweeps away the entire snowpack the avalanche can grow to medium size. Danger zones are located especially on steep shady slopes, but also in wind-loaded gullies and bowls in all aspects. Whumpf noises and fractures on the surface are alarm signals. Activities in outlying terrain away from secured ski runs require experience in evaluating the terrain and assessment of avalanche dangers. In addition, trigger-sensitive snowdrift accumulations have been generated particularly in ridgline and pass areas.

The old snowpack is overall unfavorably structured. Intermediate layers inside the snow cover continue to be only moderately bonded together. In addition, older snowdrift accumulations on shady high-altitude slopes can be prone to triggering in places. As wind velocity increases, small snowdrifts will accumulate afresh in ridgeline and pass areas.

Initially, dense cloud cover, usually above summit level, conditions improving in late morning, significantly better visibility and increasing sunshine. At 2000m: -6 to -2 degrees; at 3000m: -8 degrees. Light to moderate velocity southerly winds at high altitudes.

Avalanche danger levels are not expected to change significantly. Main danger at high altitudes remains the unfavorably structured snowpack. Fresh drifts are prone to triggering.
