Lechquellen Mountains

Beware drifts at high altitudes. Glide-snow/loose-snow avalanches will persist.

Beware drifts at high altitudes. Glide-snow/loose-snow avalanches will persist.

Avalanche danger is moderate. Main problem: older snowdrifts. Danger zones occur in steep wind-loaded terrain and behind protruberances, as well as in gullies and bowls, increasingly frequent with ascending altitude. Blanketed drifts are hard to recognize. Slab avalanches can be triggered by 1 person. Lower layers in the snowpack can be triggered mostly by large additional loading, esp. in transitions from shallow to deeper snow, e.g. entries into gullies and bowls. Below 2400 m glide-snow avalanches can be expected in extremely steep terrain, forest lanes and on smooth grassy slopes which have not yet discharged, becoming large with ascending altitude. Exposed zones can be placed at risk thereby. Caution below glide cracks. Increasing loose-snow avalanches are possible during the day.

The latest round of snowfall has settled, up to intermediate altitudes it has bonded with the old snowpack. At high altitudes this process takes longer. Gusty winds were moderate, small snowdrift accumulations were generated. These and the fresh snow are often prone to triggering. At intermediate altitudes the snowpack is moist down to the ground, despite dropping temperatures. Gliding movements continue to be possible.

Nocturnal hours: dry and clear. Sunday: Very sunny and mild, only few thin cloudbanks. Zero-degree level will ascend to 3300 m. At 2000 m: -2 to +8 degree. Moderate to light N/Nw winds.

Also Monday will be very sunny and very mild. Gliding snow activity will increase again, also loose-snow avalanches. The danger of dry-snow avalanches will decrease.
