Slabs still triggerable by large additional loading.
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
Due to mild temperatures the snowpack will settle and stabilize. There is little snow in south aspects which is encrusted in the morning before softening during the course of the day. In north aspects at high altitudes, foehn winds will locally generate shallow snowdrift accumulations. In addition, from place to place trigger-sensitive interim layers persist in the uppermost part of the snowpack. Fracture propagation over wide-spread areas is not likely. In wind-exposed areas, the snowpack surface is wind-compacted; on shady side slopes at higher altitude there is still loose snow on a stable old snow base.
Tendency
Avalanche danger levels will remain low.

Be careful of fresh snowdrifts.
Freshly generated snowdrift accumulations are small-sized yet still often prone to triggering, particularly 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.

Weak layers in the old snowpack can in isolated cases on shady slopes be triggered even by one sole skier. Caution urged esp. in transitions into gullies and bowls above 1800m and at the foot of rocky cliffs and behind protruberances in the landscape. Avalanches are mostly small-sized. Apart from the risks of being buried in snow masses, the dangers of being swept along and forced to take a fall need to be taken into condideration.

Avalanche danger above 1600m 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/E facing slopes, caution also urged near treelines and in forest clearances. Size and frequency of danger zones tend to increase with ascending altitude. As of 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
Fresh and older 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.

With the south wind on shady slopes fresh, poorly bonded snowdrift on top of surface hoar!
The avalanche danger above the treeline 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 start in lightly forested areas and increase with height. Spontaneous loose-snow avalanches on sunny extremely steep rock areas are possible.
Snowpack
Due to mild sunny weather the snow cover has settled in sunny high-altitude slopes. On shady slopes driftsnow-which formed during precipitation Wednesday-is prone to triggering in some places. Also du to south winds there can driftsnow can form again which will be poorly bonded to the predominantly existing surface hoar. In addition persistent weak layers are there for a longer period due to low amounts of snow and faceted snow layers and crusts which are weakening the snow base.
Tendency
Due to cooling tension within the snowdrift are persistent.

Snowdrift accumulations prone to triggering
Small-area avalanche prone locations in the form of fresh and older 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 are generating fresh snowdrift accumulations, they will 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.

Only isolated danger spots due to snowdrift in shady areas.
The avalanche danger is low. In some danger spots slab avalanches can be triggered by small additional loads. These are in general small. 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 winter so far-which was cold and without lots of snow- reflects the composition of the snowcover. The snow base is formed by a succession of crusts in which weak layers and faceted snow is found. In shady slopes small amounts of older snowdrift and now with the south wind blown-in snow. On sunny slopes the snow cover has settled.
