Avalanche danger above the treeline is moderate. Danger zones can release small slab avalanches by one sole skier. Danger zones occur particularly in ridgelines zones and behind protruberances in the landscape. Small-to-medium glide-snow avalanches still possible. Caution urged below glide cracks.
Up to 10-20cm of fresh snow was registered, locally more. Weak layers for slab avalanches lie inside the fresh snow and fresh drifts. On shady slopes above 2000m the old snowpack can itself be a weak layer. Above 2200m there are several weak layers of faceted crystals inside the old snow, often prone to triggering. The entire snowpack can glide over steep rocky plates or grass-covered slopes.
Light snowfall during the nocturnal hours, with clouds then dispersing temporarily. Temperatures rising. At 2000m: from -5 to 0 degrees. On Wednesday, dense clouds in the Northern Alps, visibility often reduced. Southerly winds at high altitudes of the Tauern will be brisk, windspeeds reaching 60 km/hr, elsewhere winds will be noticeably lighter. During the daytime temperatures will rise. At 2000m from 0 to +5 degrees, at 3000m: from -7 to -2 degrees.
Avalanche danger levels expected to decrease slightly
