As a result of resh snow and increasingly stormy winds, wide-reaching snowdrift accumulations have been generated particularly in gullies and bowls and behind protruberances in the landscape in all aspects above 2200m. Avalanches can fracture down to more deeply embedded layers inside the snowpack on shady slopes in particular, and then grow to larger size. Remote triggerings are possible. Whumpf noises and glide-cracks when the snowpack is tred upon are indicators of danger.
Since Friday there has been up to 30m of fresh snow along the Salzburg border. Regionally another 15 cm is anticipated, locally more. Often storm-strengh winds will transport the fresh snow. The cold fresh snow and fresh snowdrifts which lie deposited particularly in gullies, bowls and behind irregularities in the landscape, lie atop a weak old snowpack surface in all aspects above 2200m. Inside the old snowpack on shady wind-protected slopes there are faceted, expansively metamorphosed layers, particularly above 2200m. Observers in outlying terrain report of naturally triggered avalanche releases, thus confirming the poor quality of the snowpack. Over small areas, it is highly irregular.
Stormy weather in the mountains, winds reaching peaks over 100 km/hr in exposed terrain The Main Alpine Ridge will be shrouded in fog all day long, light snowfall is expected. At 1000m: -1 degree; at 2000m: 8 degrees; at 3000m: -14 degrees.
