Low avalanche danger - thin snowdrift patches behind abrupt discontinuities in the terrain
On Monday morning, a thick cloud layer at intermediate altitude will blanket the mountains of Styria in fog. As of midday this will disperse from the west, a sunny afternoon will begin. Winds will shift to westerly, by evening in the Koralpe a brisk wind will develop. Temperatures will rise at all altitudes. At 2000 m: +6 degrees.
On Tuesday, the summits will be veiled in heavy cloud, from the west rainfall and snowfall will set in. Snowfall level will lie at 1600 m (Dachstein region) and 2000 m (Koralpe), then descend during the course of the day to 1000 m-1500 m. A wet snow problem will threaten up to high altitudes.
Low avalanche danger - thin snowdrift patches behind abrupt discontinuities in the terrain
Avalanche danger is low. Isolated danger zones lie in extended eastern aspects. Snowdrift patches can be triggered in the morning hours be large additional loading. But only magnitude 1 releases are expected, in treacherous zones magnitude 2.
The snowpack has settled well. Stormy NW winds are transporting snow onto a hardened old snowpack surface. The snowdrift patches have poor bonding to the old snowpack. As temperatures drop, it freezes at intermediate altitudes. In Graz mountains there is little snow on the ground.
