Partially moderate avalanche danger - considerate fresh snowdrift
Partially moderate avalanche danger - considerate fresh snowdrift
Avalanche danger above the treeline to moderate. Danger spots are located in very steep entries, gullies and behind ridgelines in the expositions north to east. There slab avalanches can be triggered by small additional loads.
In higher altitudes a fresh snowdrift cover accumulates north and east on top of a snow surface which is weakened by kinetic metamorphosis. This weak layer can be disturbed. Otherwise the new snow bonds very good with the old snow cover only in some places the bonded layers with different hardness can be prone to triggering. Weak layers within the snow base (kinetic metamorphosis) can hardly be triggered. Blow-off areas are often hard and icy.
Wednesday night precipitation is called throughout whole Styria. In the morning of Thursday the precipitation is clearing up in direction east and Fischbacher Alps. Snowline is 1.000 m.
