Low avalanche danger, only little snow.
Low Avalanche danger. A few danger spots due snow drift deposits in high altitude gullies and bowls and steep areas. There small slab avalanches within the old snow can be triggered by high additional loads. Danger of being swept away or being buried! Hazards of falling is to be considered as well!
In the southern and eastern Styrian mountains only in shady high altitude slopes a snow cover is existing. Exposed areas are blown-off and bare or icy. In gullies and bowls snowdrift has accumulated. In shady high altitude slopes faceted snow crystal underneath old snowdrift accumulations can weaken the snow cover. Surface hoar has formed during the clear nights which lasts only in shady areas. In sunny areas the snow cover gets moist and soft.
The high pressure system comes to its end. Nights are predominantly clear and the morning will still be sunny but during the course of the day clouds form coming from north. The summit of Alpenhauptkamm will be foggy in the afternoon. Light snowfall will start in the evening. Vivid southwesterly winds are cooling off. Temperatures at noon in 2.000 m are 1 degrees but decreasing during the afternoon. Thursday night the temperatures will drop and light snowfall starts. Temperatures in the north and central Alps will drop to 2-digit Minusdegrees on 2.000 m.
Some new danger spots are to expect depending on the amounts of new snow as well as snowdrift.
