Moderate Avalanche Dance due to increasing old snow problem 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 are affected. Medium-sized slab avalanches can be triggered with small additional loads. 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 can form 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 Tuesday.

Little snow but moderate Avalanche danger due to old snow problem in high altitudes!
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 in the old snow in high altitudes and shady slopes. Especially the expositios north to southeast close to the Alpenhauptkamm behind ridgelines and the beginnings of gullies and bowls are affected. Small to medium slab avalanches can be triggered with small additional loads.
Snowpack
South of the Alpenhauptkamm the snowcover is still thin. Exposed areas are blown-off and icy. Due to wind transfer, there is a bit more snow in gullies and bowls. The snow base doesn’t have significant weak layers. In shady high slopes there are faceted snow layers in the old snow which form weak layers. Surface hoar has formed which stays only in shady areas. In sunny sides the surface turns wet or firn-like.
Tendency
No significant changes of the avalanche danger. The high pressure system will last till Tuesday.

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.
Snowpack
In the southern and eastern Styrian mountains the snowcover is still thin. Exposed areas are mainly blown-off and bare or icy. In gullies and bowls the snow cover is a bit thicker. The snow base doesn’t have significant weak layers. In shady high slopes in places faceted snow forms weak layers within the old snow. In the past clear nights surface hoar has formed which stays only in shady areas. In sunny sides the surface turns wet or firn-like.
Tendency
No significant changes of the avalanche danger. The high pressure system will last till Tuesday.
