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 in ridgeline terrain, gullies and bowls, freshly generated but usually small-sized snowdrift accumulations require attentiveness.

The old snowpack generally is superficially melt-freeze encrusted or, in places iced over. 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. Surface hoar frequently has formed. 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.

Also on Monday, lots of sunshine in the mountains. Temperatures are expected to recede slightly at high altitudes. At 2000m: again 0 to +5 degrees, at 3000m dropping during the course of the day from 0 to -4 degrees. Light to moderate northwesterly winds at high altitudes.

Avalanche danger expected to remain low
