Low avalanche danger, but isolated danger zones on shady high-altitude slopes. Glide-snow activity on south-facing slopes.
LOW avalanche danger prevails. Isolated avalanche prone locations occur especially on shady slopes in transitions from shallow to deep snow (persistent weak layer), and on east-facing slopes and behind protruberances. . In isolated cases, the weak layers in the old snow can trigger a medium-to-large sized avalanche. On sunny slopes, steep grass-covered terrain can expect naturally triggered glide-snow avalanches. Glide cracks (‘fishbones’) should be seen as red flags.
On sunny slopes the snowpack is covered by a melt-freeze crust. On shady slopes the weak layers deeper down inside the snowpack are a threat. On sunny slopes, glide cracks have formed on steep grass-covered slopes.
Sunshine over widespread areas from the start. Brisk SW/SE winds, gusts reaching 20-40 km/hr. At 2000 m: about -2 degrees.
Monday will be very sunny. Brisk S/W winds, reaching stormy strength in Koralpe region. Avalanche danger is not expected to change significantly.
