Lechquellen Mountains

Isolated avalanche prone locations occur in persistent weak layer of old snow.

Isolated avalanche prone locations occur in persistent weak layer of old snow.

In isolated cases avalanches can be triggered in persistent weak layers on very steep shady slopes in high alpine regions. These releases are mostly small-sized. The risks of falling and sustaining injuries outweigh those of being buried in snow masses. At very high altitudes over minor areas, freshly generated but small-sized snowdrift accumulations require attentiveness.

The old snowpack is superficially melt-freeze encrusted and generally hardened. It softens up slightly during the daytime hours, particularly on sunny slopes. Beneath the melt-freeze crusts, particularly on steep north-facing slopes, expansively metamorphosed crystals weaken the shallow snowpack. At high altitudes, small-sized snowdrift accumulations occur from place to place. On shady slopes in high alpine regions, isolated weak layers occur inside the snowpack. South-facing slopes are bare of snow up to high altitudes. Only limited information from outlying terrain is currently available to the Avalanche Warning Services.

Dry air masses at high altitudes above the high fog guarantee outstanding visibility and brilliant sunshine. Temperature at 2000m: -1 to +4 degrees, at 3000m: 0 degrees. Brisk easterly to northeasterly winds at high altitudes.
