Quite favorable backcountry touring conditions

Overall quite favorable conditions prevail, avalanche danger is low. Isolated avalanche prone locations occur on shady, steep ridgeline slopes and behind protruberances, and in transitions from shallow to deep snow above 2400 m, particularly in laterally-skied steep terrain, mostly by large additional loading they can trigger locally. Due to daytime warmth and solar radiation, glide-snow avalanches are possible, especially below 2200 m on steep sunny slopes. Caution urged near large cornices.

It wasn’t quite as cold last night as the night before but the outgoing longwave radiation was still good, due to cloudless skies. Thus, the south-facing slopes formed a crust capable of bearing loads, on SE and SW slopes often not capable. On NE/N/NW slopes there is still loose snow. Above 2200m on north-facing slopes the snowpack is expansively metamorphosed (faceted). Near ridges on very steep slopes and in transitions from shallow to deep snow above 2400 m on W/N/E facing sleops there are isolated weak layers embedded inside the snowpack which are prone to triggering. Below 2000 m the snowpack is partially moist, which enhances the gliding movement of the entire snowpack over very steep grass-covered slopes.

Pure sunshine in the mountains of Vorarlberg from early until late, cloudless skies, only light winds, milder temperatures. At 2000 m: -5 to -1 degree. Light to moderate NE winds.

The weather forecast foresees sunny weather continuing until Sunday, and slowly rising temperatures. Foehn influence starting on Friday will be noticeable. The danger of wet-snow avalanches will increase with daytime warming and solar radiation.
