Avalanche danger is moderate due to persistent weak layers in high-altitutde areas!
The avalanche danger above 1.800 m is moderate. In shady areas slab avalanches can be triggered by small additional loads. These avalanches are usually small but can reach medium size in some places. Danger spots are usually located in shady northwestern to eastern expositions especially in transitions from little to much snow, in entries to steep gullies and bowls and behind ridgelines. The danger areas increase with height.
Snowpack
Due to mild sunny weather the snow cover got soft in sunny high-altitude slopes. On shady slopes driftsnow is prone to triggering in some places. which is poorly bonded to the predominantly existing surface hoar. In addition faceted snow layers and crusts which are weakening the snow base especially on shady slopes.
Tendency
On Thursday sunny mountain weather is called. Avalanche danger doesn´t change significantly.

Snowdrift accumulations: assess them with caution
Small-area avalanche prone locations in the form of snowdrift accumulations, esp. in wind-loaded steep terrain, in gullies and bowls, and behind protruberances in the landscape, on shady slopes often triggerable above the treeline by one sole skier and then possibly growing to medium size. However, the danger zones are easy to recognize for the practiced eye, thus, should be circumvented. In high-alpine regions the danger zones occur more frequently and the risks are greater. On steep shady slopes at high altitudes where the snow is shallow and in transitions from shallow to deep snow, slab avalanches can be triggered. A cautious route selection is imperative. At lower altitudes, isolated small avalanches are possibly triggered in extremely steep terrain. Naturally triggered small loose-snow avalanches are possible on extremely steep sunny slopes.
Snowpack
Moderate-to-strong southerly winds have generated fresh snowdrift accumulations, they lie deposited on shady steep slopes atop weak layers and are prone to triggering. Elsewhere, the snowpack is stabilizing. The near-surface layers are still generally loosely-packed, except where winds have had their effect. There are lots of wind crusts and, on south-facing slopes, a shallow surface crust. More deeply embedded layers inside the snowpack are unlikely to trigger, at most where the snow is shallow and on very steep shady slopes. Particularly in sunny aspects, glide cracks are opening again on steep grassy slopes.

Snowdrift accumulations still trigger-sensitive, esp. on steep shady slopes at high altitude
Avalanche danger above the timberline is MODERATE, below that altitude danger is low. In all aspects, small-to-medium slab avalanches can be triggerd by minimum additional loading in places. Danger zones occur mostly near ridgelines and behind protruberances in the landscape, esp. on W/N/NE facing slopes, caution also urged near treelines and in forest clearances. Size and frequency of danger zones tend to increase with ascending altitude. Above 2000m, releases can fracture down to more deeply embedded layers inside the snowpack and grow to larger size. Small glide-snow and loose-snow avalanches can trigger naturally. Avalanche danger above 2000m is MODERATE, below that altitude danger is low. Slabs, mostly small-sized, can be triggered even by minimum additiional loading both near to and distant from ridgelines and behind protruberances in the landscape on north, northwest and south facing slopes. If they fracture down to more deeply embedded layers in the snowpack the releases can grow to medium size. Isolated glide-snow avalanches reaching medium size are possible at any time of day or night.
Snowpack
Often hardened snowdrift masses lie atop an expansively metamorphosed, loosely-packed snowpack surface with near-surface faceted crystals. Near surface crusts are weak layers of faceted, expansively metamorphosed crystals. Particularly in shady, shallow-snow zones there is snow which is rewarding to skiers, it is faceted, expansively metamorphosed powder which is settling increasingly with rising temperatures. In general, too little snow on the ground for this juncture of the season.
Tendency
Snowdrift problem receding further. Snowdrift problem stabilizing increasingly.
Danger level
Little snow on the ground.
Avalanches are hardly possible in gullies and bowls. Only little snow is on the ground.

Snowdrifts at high altitudes still prone to triggering in places
Particularly in ridgeline zones and in very steep gullies and bowls, small-area freshly generated snowdrift accumulations are evident, mostly small sized but prone to triggering. Esp. on shady high-altitude slopes they can be triggered even by one sole skier. Danger zones tend to increase in frequency with ascending altitude, evaluate these with high caution wherever falls are possible. Naturally triggered small loose-snow avalanches are naturally triggerable on extremely steep sunny slopes.

Be careful of fresh snowdrifts.
Freshly generated snowdrift accumulations are small-sized yet still often prone to triggering, particularly in gullies and bowls along the Salzburg border, such danger zones are easy to recognize. Avalanches can in isolated cases fracture down to more deeply embedded layers in the old snopwack and then grow to medium size. On shady slopes and in high alpine zones the likelihood of triggering is higher. Caution urged especially in seldom-skied terrain.

Freshly generated snowdrift accumulations lie deposited particularly above 2400m were depositedon W/N/E facing slopes. More deeply embedded inside the old snowpack are faceted, expansively metamorphosed weak layers, esp. on shady wind-protected slopes. Clear skies are forecast, with low temperatures and low air moisture. Thus, the snowpack will expansively metamorphose during the nocturnal hours. The snowpack is highly diverse even over small areas.

Caution urged towards the risks of taking a fall
Avalanche danger is low. Locally, weak layers in the old snowpack can be problematic. Small slab avalanches can be triggered in isolated cases by large additional loading, which happens more likely in places with little snow. Avalanche prone locations occur in extremely steep ridgeline terrain in W/N/E aspects as well as at entries into gullies and bowls. Dangers of being swept away and of taking a fall outweigh those of being buried in snow masses.
Snowpack
The snowpack is stable by and large. At high altitudes, foehn winds have generated shallow snowdrifts on north-facing slopes. In addition, trigger-sensitive intermediate layers in the uppermost part of the snowpack have persisted. Fracture propagation is unlikely. On south-facing slopes there is little snow on the ground, mostly encrusted in the morning hours before softening up later on. In wind-exposed terrain the surface is wind-pressed, on shady slopes with little wind there is still loosely-packed snow.
Tendency
Avalanche danger levels will remain low.

Treeline
Only isolated danger spots due to snowdrift in shady areas.
The avalanche danger is low. In some places slab avalanches are possible. Danger spots are located in in shady slopes and steep areas adjacent to ridgelines, in high-altitude entries into gullies and bowls and behind terrain edges. In case of triggered avalanches risk of injuries is more likely than risk of being buried.
Snowpack
The snow cover is unusual thin for this season and southern slopes as well as exposed areas are predominatly bare or icy. An area-wide, coesive snow base is only existing in blown-in gullies and bowls and shady high-altitude slopes. That snow cover is charactized by equilibrium (isothermal) metamorphosis. It is succession of soft layers on the surfacs, partially powder snow, and faceted snow crystals with melt-freeze crusts.

Danger of taking a fall outweighs that of being buried in snow
Avalanche danger is low. Particularly on very steep shady slopes above the timberline, slab avalanches can be triggered in isolated cases by minimum additional loading. Releases are mostly small-sized. Apart from th 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.

Older snowdrift accumulations are generally small-sized, triggerable only in isolated cases, esp.on wind-protected shady slopes above 2000m, esp. in transitions into gullies and bowls and at the foot of rocky cliffs and behind protruberances in the landscape. Apart from the risks of being buried in snow masses, the danger of being swept along and forced to take a fall require consideration.
Snowpack
The older snowdrifts blanket a weak old snowpack. The snowpack is highly diverse even over small areas. Only little snow on the ground from region to region below 1600m. Clear nighttime skies are forecast, with low temperatures and low air moisture. Thus, the snowpack will expansively metamorphose during the nocturnal hours.
