Ybbstaler Alpen

Sunlight and warming can spontaneously loosen damp slides.

Sunlight and warming can spontaneously loosen damp slides.

The avalanche danger is categorised as low (level 1). The main problem is small, wet slides, which can be triggered in a few places by additional load. Spontaneous, small loose snow slides are also possible in isolated cases, especially from steep slopes in southern and eastern aspects. With the sunshine and rising temperatures, the danger of spontaneous loose snow slides increases slightly during the daytime changes. In shady gullies and bowls above the tree line, there are still prone to triggering snowdrift accumulations. These can be triggered by a single person as a small slab avalanche.

The wind slab, which was deposited on a soft layer of snow with graupel, is only occasionally prone to triggering in shady gullies and bowls due to the warming and rain up to an altitude of 1700 metres. Due to the rain and warming, the snow cover, snowpack has lost firmness, especially at altitudes below 1700 metres. Due to the continuing rise in temperatures and solar radiation, the moisture in the snow cover, snowpack, in particular in southern and eastern aspects, increases significantly up to the summits during the daytime changes.

It will be cloudy through the night on Wednesday. High fog or mist will only gradually form over the lowlands. However, with an upper limit at around 600 metres, this will be quite irrelevant for the mountains. On Wednesday morning, sunshine will predominate in the Lower Austrian mountains, with thicker clouds only moving through in the afternoon. However, it will remain dry. The temperature at an altitude of 2000 metres will be between -1 and 2 degrees. The temperature at an altitude of 1500 metres will be between 3 and 6 degrees. There will be strong winds with gusts of around 90 km/h from the west. The snowfall level is between 1700 and 2200 metres above sea level. No new fallen snow is expected.

The avalanche danger will remain the same on Thursday. The danger of wet loose snow avalanches is even decreasing. In the coming days, the weather will continue to be characterised by high pressure and mild temperatures. Although dense clouds will occasionally cover the sun, rain or snowfall is not expected for the time being. The high fog in the lowlands will become denser and gradually reach up to altitudes of around 1000 metres.
