Low avalanche danger, only little snow. Observe risk of falling.
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. Some areas with thin snowdrift deposits can form. Danger of being swept away and buried as well as risk of falling is to be considered.
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.
Tendency
No significant changes of the avalanche danger situation.

The main problem is fresh snowdrift. In higher altitudes persistent weak layers in some areas.
The avalanche danger is slightly increasing and on moderate level above the treeline. New danger spots forme due to snowdrift accumulations especially in the extended expositions north and east prone to triggering. The higher the altitude the higher the amount of danger spots. In very steep, shady and high slopes slab avalanches within the old snow can be triggered by small additional loads. These can reach medium sizes. Especially on transitions between thin and thicker snow covers spontaneous gliding snow avalanches are possible. Avoid areas below glide cracks.
Snowpack
Thursday new snow will land with strong wind influences. This snowdrift (bonded) accumulates on a loose snow layer in shady slopes. This layer is built by kinetic metamorphism (faceting) - in sheltered locations also by surface hoar - and is a potentially breakable crust for slab avalanches. In shady high altitudes the snow cover is weakened by layers of faceted crystals and -in some areas- snown in Graupel within the old snow. On smooth surfaces the snow cover can start gliding anytime.
Tendency
Danger of slab avalanches (wind slab problem). Small spontaneous loose-snow avalanches coming from steep terrain are possible due to radiation.

Persistent weak layers in high altitudes! Observe: fresh snowdrift deposits are present in some areas.
Moderate avalanche danger above 1.900 m, below that: low avalanche danger. Danger spots are located in high shady slopes behind ridgelines and in the beginnig of gullies and bowls as well as steep slopes. Slab avalanches within the old snow can be triggered by small additional load and can reach medium sizes especially in transition areas from thin to thicker snow covers. Due to the new snow amounts and the strong winds snowdrift deposits which are prone to triggering are possible which are to consider especially for risk of falling. Also spontaneous gliding snow avalanches are possible. Avoid areas below glide cracks.
Snowpack
Due to the cold front it’ll get cold and windy but only little snow. The new snow is drifting and accumulates as bonded layer on a loose old snow cover in shady slopes. The bonding between driftsnow and old snow is only poor. Summits are blown-off and icy or bare, gullies and bowls are filled with snowdrift. In shady high altitudes the snow cover is weakened due to layers of faceted snow crystals and sometimes snown in Graupel within the old snowdrift accumulations. Surface hoar has formed especially in basins. On smooth surfaces the snow cover can start gliding any time.
Tendency
No significant changes of the avalanche danger situation.
