Lechquellen Mountains

Main danger: wet-snow avalanches. Beware fresh snowdrifts in high-alpine zones.

Foehn winds will taper off on Thursday, the air will become moister, clouds and fog will increase. Precipitation can be increasingly expected, the snowfall level will descend only gradually to 2000m. At 2000m: +5 degrees during the daytime. Initially strong S/SE winds, later on tapering off.

Due to temperatures dropping and winds slackening off, avalanche danger will recede.

Main danger: wet-snow avalanches. Beware fresh snowdrifts in high-alpine zones.

Avalanche danger below 2800m is considerable, above that altitude danger is moderate. On steep slopes in all aspects which have not yet discharged, wet-snow and glide-snow avalanches can trigger naturally and grow to medium-to-large size. In high-alpine zones, fresh snowdrift accumulations require attentiveness, they are usually small, but often easily triggered. Danger zones occur in gullies, bowls, behind protruberances in the terrain and on very steep shady slopes above 2800m. In addition, winter sports enthusiasts can trigger small-to-medium avalanches in the old snow in isolated cases. Danger zones occur in little-tracked backcountry terrain, mostly on very steep NW/N/NE-facing slopes and are difficult to recognize.

Outgoing longwave radiation during the night from Wednesday to Thursday will be very poor due to moist-warm air masses and some rainfall. Due to strong-velocity S/SE winds, small snowdrift accumlations will be generated which will be deposited stop soft layers, particularly on shady slopes in high-alpine zones, and be prone to triggering. On south-facing slopes there is hardly any snow on the ground up to high altitudes. Also on shady slopes the ground is becoming bare of snow up to intermediate altitudes. On very steep shady slopes at high altitudes there are unfavorable intermediate layers inside the snowpack.
