Moderate Avalanche Dance due to increasing persistent weak layers in high altitudes! Spontaneous wet- and gliding snow avalanches on sunny slopes.
Moderate avalanche danger above 1.900 m, below that: low avalanche danger. Danger is caused by older driftsnow deposits which are located on a weak layers within the old snow. Especially the expositios northeast and southeast behind ridgelines and the beginnings of gullies and bowls as well as steep slopes are affected. Medium-sized slab avalanches can be triggered with small additional loads on transition areas (thin snow layers to thicker snow cover). On sunny slopes spontaneous small-sized wet and gliding snow avalanches are possible.
Snowpack
Exposed areas such as summits are blown-off and icy. Due to wind transfer, there is snowdrift in gullies and bowls. In shady high slopes there are faceted snow layers in the old snow which are increasingly forming weak layers. Surface hoar has formed which stays only in shady areas. In sunny sides the surface turns wet or firn-like. On smooth surfaces the snow cover starts gliding on sunny slopes.
Tendency
No significant change of the avalanche danger. The high pressure system will last till Wednesday.

Low avalanche danger, only little snow.
Low Avalanche danger. A few danger spots due snow drift deposits in gullies and bowls. There small slab avalanches can be triggered by high additional loads. On sunny slopes small wet snow avalanches are possible.
Snowpack
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 stays only in shady areas. In sunny areas the snow cover gets moist and firm-like during the course of the day and gets bare quickly.
Tendency
No significant changes of the avalanche danger. The high pressure system will last till Wednesday.
