Lechquellen Mountains

Caution: snowdrift accumulations blanket weak layers of old snow.

Caution: snowdrift accumulations blanket weak layers of old snow.

With increasing altitude, older snowdrift accumulations are prone to triggering. They are blanketed and thus, impossible to recognize. One single winter sports enthusiast can trigger slab avalanches. Also remote triggerings are possible. Danger zones occur in steep ridgeline terrain, in wind-loaded gullies and bowls as well as behind sharp drops in the terrain. Triggered avalanches can sweep away deeper layers of the old snowpack and grow to medium size. Such avalanche prone locations occur particularly on steep shady slopes and are not visible. Activities in backcountry require cautious evaluation of the terrain and avalanche dangers, as well as restraint. On sunny slopes, generally small-sized loose-snow avalanches can trigger naturally during the course of the day.

The 5cm of fresh snowfall, locally more, from yesterday and the snowdrifts from previous days lie deposited at high altitudes atop loosely-packed snow and a weak old snowpack surface, particularly on steep shady slopes. The snowdrift accumulations are blanketed, making them impossible to recognize. Avalanches by winter sports enthusiasts, remote triggerings and fractures forming on the snowpack surface confirm how prone to triggering the snowpack is.

Again on Sunday, tranquil winter weather will prevail accompanied by only light winds. Apart from flat cloudbanks between Lake Constance and the Rhine Valley (upper limit at 600m) it will be quite sunny, with only a few residual clouds during the course of the day. Wintery temperatures. Low: -6 to 0 degrees; high: +1 to +5 degrees.

Avalanche danger will decrease only gradually.
