Fresh wind slab prone to triggering.

Fresh wind slab prone to triggering.

With new fallen snow and a stormy wind from the north-west, fresh prone to triggering snow packs are formed, which can be triggered by individuals in a few places from around 2200 metres. They are deposited on an unfavourably building snow cover, snowpack. Where there is more precipitation locally, enough snow can accumulate to bury people, especially in terrain traps. Take care behind exposed ridges and ridgelines, in gullies and bowls. In shady slopes at high altitudes, there are still very occasional release points in persistent weak layers that are difficult to disturb. The risk of injury from stones is not easily recognisable everywhere.

Fresh windslab snow is deposited on the highly variable and crusted old snowpack, more in the north than in the south. The connection is generally rather poor. In shady slopes, weak layers of faceted crystals are occasionally preserved in the snow cover, mostly in the vicinity of crusts. Due to the overall heavily built-up transformed snow cover, the fracture propagation potential in the persistent weak layer is generally low.

It will start to snow lightly from the Steinberge mountains in the morning hours on Tuesday and it will be significantly colder. In the northern Alps, visibility will be limited and light snowfall will prevail from the start, while visibility in the central Alps and Lungau will often be good with some sunshine at the beginning. More clouds will soon move through everywhere, with the most snow falling from the Steinberge to the Dachstein (10, maximum 15 cm by midday). The snow showers will largely subside by the evening. The wind will blow brisk to strong from the northwest, stormy from the northwest throughout the high alpine terrain, strongest in the Niedere Tauern with peaks of 100 - 110 km/h in exposed terrain. Temperatures at 2000 m are around -11 degrees, at 3000 m between -20 and -18 degrees.

The avalanche danger increases slightly with more new fallen snow and wind on Wednesday.
