Generally low avalanche danger, but caution urged towards snowdrifts
Low avalanche danger in general, but attentiveness urged towards snowdrift patches in landscape concavities which are poorly bonded with the snowbase beneath them, in these danger zones isolated small slab avalanches can be triggered. In shady terrain above the timberline there is a persistent weak layer. Slab avalanches cannot be ruled out. Caution urged towards the peril of falling on icy surfaces.
At low altitudes the snowpack is moist and, depending on altitude, covered with a melt-freeze crusts which is often capable of bearing loads. At high altitudes the surface is iced over, hardened or wind-compacted. The fundament beneath that is compact by and large, and evidences hardly any weak layers. Above 1500 m on shady slopes the snowpack is metamorphosing expansively, the snowpack consists of more and more faceted crystals, it is forfeiting its firmness and losing its base.
Wednesday will enjoy cloudless skies in most of the mountain regions. Winds from the northwest will intensify on the eastern Alpine rim in particular. From the west the temperatures will rise somewhat. At 2000 m: in Totes Gebirge at midday -4 degrees, on the Hohen Veitsch -8 degrees. On Thursday, extensive sunshine during the morning in some regions. Cloud cover will increase hour by hour, in the afternoon there will be little sunshine left. Winds will intensify.
Avalanche danger is expected to remain low.
