Prone to triggering wind slab snow in the higher elevations! Beginning of wet snow problems at lower altitudes.

Prone to triggering wind slab snow in the higher elevations! Beginning of wet snow problems at lower altitudes.

The avalanche danger is rated as "moderate" above the tree line. Stormy north-westerly winds create fresh drift snow packs, which in some places can be triggered by individual winter sports enthusiasts as medium slab avalanches. Spontaneous wet snow slides and smaller gliding avalanches can occur at lower elevations.

Stormy north-westerly winds and some new fallen snow are increasingly forming fresh snowdrift accumulations. The connection between the drift snow packs and the old snowpack is insufficient in places. Prone to triggering weak layers in the form of snow deposits of varying hardness also exist in places in the bound layer. In shady high altitudes, the old snowpack is unfavourably structured in places with crusts and embedded faceted crystals. With increasing moisture penetration, the snowpack loses stability at lower altitudes and can also start to glide snow on steep grass and forest slopes.

In the second half of the night on Tuesday, heavy precipitation will set in in places on the northern side of the Alps with snowfall levels between 1000 and 1300 metres. On Tuesday, the mountain peaks of Lower Austria will initially be covered in thick clouds. In total, between 5 and 15 cm of new fallen snow may fall on the mountains. In the east, the precipitation will decrease in the afternoon and the chances of clearing will increase. A gale-force north-westerly wind will prevail at high altitudes. The temperature will be around 0 degrees at 1000 metres and -3 degrees at 2000 metres.

With the influence of high pressure and a strong rise in temperatures on Wednesday, the wet snow problem will increase!
