Prone to triggering snowdrift accumulations and stones are the main danger
The avalanche danger is low. Above 2200 m, slab avalanches can be triggered in a few places by slight additional load in the wind slab, but they usually remain small. Be careful in the area of terrain traps, as there could still be enough snow here to bury people. Danger areas due to wind slabs are located particularly behind terrain edges in areas adjacent to the ridgeline, crest or summit. Drift snow packs are sometimes covered by little new fallen snow and are not always easily recognisable. Beware of stones under the thin snow cover, snowpack.
The snow cover, snowpack is highly variable. Since Friday, 5 cm, in some places even 10 cm of new fallen snow has accumulated. Some of these cover older drift snow packs on the otherwise crusted can form snow surface. Prone to triggering weak layers are most likely to be found in the fresh snow packs and at the transition to the melt-freeze crust. Below this, on the shady slope, there is a sequence of layers of faceted crystals and melt-freeze crusts, but the potential for fracture propagation is generally low due to the heavily built-up transformed snow cover. On the sunny slope, the snow cover, snowpack is hard and crusted can form. The snow depth is still well below average at all altitudes.
During the night, clouds move through for the time being, with only light snowfall in the Niedere Tauern. The clouds will clear from midnight. Mostly weak to moderately strong winds from the west, which can reach speeds of around 40 km/h at high altitudes. On Sunday, the sun will mostly shine unclouded with good visibility. The wind will ease somewhat during the day. It will continue to be very cold, at 2000 metres the temperature will be a freezing -13 to -10 degrees.
It remains cold, the new and wind slab snow only settles slowly.
