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. In ridgeline terrain, gullies and bowls at very high altitudes, freshly generated but usually small-sized snowdrift accumulations require attentiveness.

The old snowpack is superficially melt-freeze encrusted and iced over from place to place. The crust softens up slightly during the daytime hours, particularly on sunny slopes. On shady slopes beneath the melt-freeze crust, unbonded, mostly expansively metamorphosed crystals occur. At high altitudes, small-sized snowdrift accumulations have been freshly generated. On shady slopes in high alpine regions there are still weak layers inside the snowpack, and frequently surface hoar. 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.

Still lots of sunshine in the mountains to start with, particularly towards the south, and outstanding visibility in the dry air at high-altitudes. From Bavaria and further north, low-lying clouds will push their way over the Bregenzerwald borders. In the afternoon hours cloud cover will spread further south. Particularly the summits of the Allgau Alps and Bregenzerwald will become shrouded in fog, here and there are few snowflakes can be expected. At all altitudes, temperatures will drop measurably, strong-velocity northwesterly winds will sharpen the subjective feeling of cold further. At 2000m: descending from -3 to -11 degrees; at 3000m: from -7 to -15 degrees.
