Drift snow problem due to south foehn

Drift snow problem due to south foehn

The avalanche danger is moderate above 2100 metres and low below. The main problem is fresh drift snow. In the sectors from west to north to east and in gullies, slab avalanches can be triggered in some places by even a small additional load. They can occasionally break through to deeper weak layers and become medium sized if the snow is thick enough. Danger spots are mainly located close to the crest, directly on the main ridge also behind terrain edges far from the crest. Below 2800 m, mostly small sliding snow avalanches can occur spontaneously.

Some brisk southerly winds have worked the snow surface at high altitudes and formed drift snow on a small scale. Away from the influence of the wind, the snow surface is often loose on the shaded side. Overblown, loose snow and angular crystals in the old snow are possible fracture surfaces. On the sunny side, the snow cover has settled a long way up and may have hardened in the morning. In the very steep grassy terrain, it sometimes slides along the ground.

On Thursday, extensive and sometimes quite dense cloud fields will pass through. Visibility will be adequate, but the light may be very diffuse. There will only be a few sunny spells in between. A brisk southerly wind will blow in the foehn corridors of the Tauern, otherwise windy conditions will prevail. At 2000 metres between -2 and +1 degrees, at 3000 metres around -5 degrees.

The unproductive snowfall on Friday night does not change the situation significantly.
