Avalanche danger levels are moderate. Freshly generated snowdrifts can be triggered as a small-to-medium sized slab avalanche in some places. Size and frequency of danger zones tend to increase rapidly with ascending altitude, but also forest clearances at low altitudes can be treacherous. Surface-near avalanches above 2200m can fracture down to more deeply embedded layers of the snowpack. Danger zones occur particularly on north and east-facing slopes, above 2400m also on south and west-facing slopes. Caution urged in transitions from shallow to deep snow. Naturally triggered small-to-medium sized glide-snow avalanches are possible. Circumvent zones below glide cracks.
Snowpack
There was 10-20 cm of fresh snow registered, drifts were deposited atop a loosely-packed, expansively metamorphosed snow base which can serve as a fracture surface. On sunny slopes the bonding to the often encrusted old snowpack surface is somewhat more favorable. Intermittently strong W/NW winds have compacted and transported the snow in exposed terrain. Above about 2200m there are faceted crystals evident inside the old snowpack, often of surface hoar, which can frequently be prone to triggering. The entire snowpack can glide away over steep rocky places and grass-covered slopes.
Tendency
On Sunday, superficial moistening of the snowpack due to rain impact, small naturally triggered avalanches possible

Fresh and older snowdrift accumulations can be triggered even by one sole skier. Danger zones occur particularly on steep shady slopes, in wind-loaded gullies and bowls, and behind protruberances in the terrain. Size and frequency of danger zones tend to increase with ascending altitude. Where there has been rain impact, slides and, on steep grassy slopes, small glide-snow avalanches are possible. Caution urged below glide-cracks.
Snowpack
The fresh snow and drifts lie deposited atop an unfavorable, expansively metamorphosed old snowpack surface, often atop surface hoar, on shady slopes in particular. Also inside the snowdrifts themselves there are frequently trigger-sensitive intermediate layers evident. On sunny sloppes, bonding to the old snowpack surface is better. Due to rain impact the snowpack will temporarily be weakened.

Evaluate fresh snowdrifts with caution. Attention: weak layers in the old snow.
As a result of fresh snow and moderate-velocity winds from varying directions, mostly shallow snowdrift accumulations will be generated during the night in ridgeline zones, gullies and bowls above all else. These drifts can be easily triggered, especially on NW/N/NE facing slopes, or else glide away naturally. Avalanches can fracture down to more deeply embedded layers inside the snowpack and in isolated cases along the Salzburg border, reach medium size. Size and frequency of danger zones tend to increase with ascending altitude.

The old snowpack is expansively metamorphosed, full of faceted crystals. The snowpack is highly varied, even over small areas.

Avalanche danger levels at high altitudes is moderate, below that altitude danger is low. The freshly generated, shallow snowdrift accumulations can be triggered as a small-sized slab avalanche even by minimum additional loading (one skier). Such releases can fracture down to more deeply embedded layers of the snowpack above 2200m and then grow to medium size, particularly on W/N/S facing slopes. The shallow-snow transitions into snow-filled gullies and bowls are especially treacherous. Danger zones tend to increase in frequency with ascending altitude.

On sunny slopes the bonding to the often encrusted old snowpack surface is somewhat more favorable. Above about 2200m there are weak layers inside the old snowpack consisting of faceted crystals, frequently of surface hoar, which are often prone to triggering.

All in all, there is too little snow on the ground, exposed zones are windblown, gullies and bowls filled to the brim with snow.

Consider fresh snowdrift and persistent weak layers.
The avalanche danger is moderate above the treeline. Danger spots are thin, prone to triggering snowdrift accumulations especially behind ridgelines, steep slos and blown-in gullies and bowls in the extended Exposition North and East above thetreeline. Theses aqre easily spottet for experts. In very steep, shady and high slopes slab avalanches within the old snow can be triggered by small additional loads and slab through deeper layers within the old snow. They can reach medium sizes. Danger spots are increasin in higher altitudes. on steep slopes with smooth surface spontaneous gliding snow avalanches are possible.
Snowpack
Thursday night anf during firday approx. 10 cm cold new snow with strong wind influences has fallen. 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. The bonding is on sunny slopes with crusted surface a bit better. On smooth surfaces the snow cover can start gliding anytime.
Tendency
The snow cover will get mois due to rain on Sunday. In some areas increasing of small wet loose-snow avalanches ind regions with high amounts of snow.

Circumvent fresh snowdrifts
Avalanche danger is moderate. The fresh snowdrifts can trigger a small to medium-sized slab avalanche even by minimum additional loading in some places. Size and frequency of the avalanche prone locations tend to increase rapidly with ascending altitude above the treeline. Avalanches triggered near to the surface can fracture down to more deeply embedded layers inside the old snowpack above 2200m. Danger zones occur particularly on N/E facing slopes, above 2400m also on S/W facing slopes. Caution urged in transitions from shallow to deep snow. Especially below 2400m, naturally triggered small-to-medium glide-snow avalanches are possible. Circumvent zones below glide cracks.

Danger level
Too little snow on the ground for winter sports widespread. Danger zones in gullies and bowls.
The snowdrift accumulations on steep shady NE/N/NW facing slopes above 2000m can in isolated cases trigger an avalanche usually by large additional loading. Particularly unfavorable are gullies and bowls where hardened layers blanket weakly consolidated old snow. These danger zones occur rather seldom, and are generally small-sized. Apart from the risk of being buried in snow masses, you also need to take the dangers of being swept along and forced to take a fall into consideration.
Snowpack
Snowdrift accumulations cover a weak old snowpack surface on NE/N/NW facing slopes above 2000m. The old snowpack is weak, with faceted crystals. The snowpack is highly irregular even over small areas. At all altitudes, there is too little snow on the ground for this juncture of the season.

Few avalanche prone locations
Avalanche danger is low. There are very few danger zones in shady, steep entries into gullies and bowls. Particularly by large additional loading, small slab avalanches can be triggered here in the old snowpack. As a result of only minor amounts of fresh snow and win, isolated shallow snowdrift patches can be generate. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall need to be taken into consideration.
Snowpack
Overall, there is llittle snow on the ground, exposed terrain is windblown or iced over; gullies and bowls are filled to the brim with snow. The small amounts of fresh snow and drifts form only small-sized trigger-sensitive patches. The old snowpack is being weakened, particularly on shady slopes, by expansively metamorphosed snow crystals.

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. Only in some areas thin snowdrift deposits can form which are prone to triggering. Snow cover exists only in shady high altitudes. Exposed areas are blown-off and bare or icy. In gullies and bowlsthe old snow cover ist weakend due to faceted snow crystals underneath.
