Lechquellen Mountains

Main danger: weak old snowpack layers.

Main danger: weak old snowpack layers.

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 expecially 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. Also remote triggerings continue to be possible. 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.

Southerly winds will intensify in the mountains. High-altitude cloudbanks, at times compact, will join the sun. However, the weather will remain dry, generally pleasant. At 2000m: -2 degrees; at 3000m: -7 degrees. Moderate to strong velocity southerly winds at high altitudes.

In spite of some snowfall on Saturday, avalanche danger levels are not expected to change significantly. Main danger at high altitudes remains the unfavorably structured snowpack.
