Considerable avalanche danger! Driftsnow is prone to triggering even below the treeline line.
Considerable avalanche danger above 1.600m, below that moderate avalanche danger. Danger is caused by driftsnow accumulations adjacent as well as distant from ridgelines. Most danger spots are found in the sectors east and south behind ridgelines and in the beginning of gullies and bowls even below the tree line. Slab avalanches can be triggered by small additional loads. Avalanches can reach medium sizes.
In the past days cold new snow has landed on wet snow or - in higher altitudes - powder snow. Around 30 cm new snow in the westerly Northalps which will be drifted due to the stormy northwesterly winds. The summits can be blown-off but driftsnow can accumulate below treeline. Soft layers within the snowdrift and poor bonding to the old snow base can be weak layers.
Dissolving clouds and stopping snow in the Nordstauregion in the morning. 25th will be sunny mountain weather all over Styria. Winds turn northeastward and are dying down slowly. East of Eisenerzer Alps the wind stays vivid and strong. Temperatures at 2.000 m in the west around -7 degrees and in the east around -3 degrees.
