Main danger: fresh snow and persistent weak layers
The large amounts of fresh fallen snow and widespread snowdrift accumulations can easily be triggered above 2200m or else trigger naturally. Avalanches can fracture to lower layers and sweep them away, thereby grow to large size, esp. on steep, little-tracked shady slopes above 2200m and on steep, little-tracked W/E-facing slopes above 2600m. Remote triggerings and natural triggerings can be expected.
In addition, glide-snow avalanches can be expected at any time of day or night, particularly on grass-covered slopes below 2400m in zones where precipitation has been heavy.
Snowpack
dp.6: cold, loose snow and wind
Since Saturday, 30-50cm of fresh snow has been registered, esp. at high and high-alpine altitudes. By Tuesday, 50-70cm is still anticipated, locally more. The fresh snow and freshly generated snowddrifts lie deposited in all aspects above 2000m atop soft layers. On W/S/E-facing slopes below 2400m, the fresh fallen snow lies atop a crust. Inside the old snowpack, particularly on little-tracked W/N/E-facing slopes, trigger-sensitive weak layers are evident, esp. on shady slopes above 2200m and on W/E facing slopes above 2600m.

Heavy snowfall about to set in
Above the timberline avalanche danger is considerable, below that altitude danger is moderate. Snowdrift accumulations are the major problem. Danger zones where slab avalanches can be triggered even by one sole skier occur in steep ridgeline terrain on N/E/S-facing slopes, in wind-loaded gullies and bowls, and behind protruberances in the terrain. Frequency of danger zones increases with ascending altitude. Slab avalanches can grow to medium size. In addition, the fresh snow can trigger as a loose-snow avalanche in rocky or extremely steep terrain. At higher altitudes, loose-snow avalanches can reach medium size. Small glide-snow avalanches can be expected more frequently on steep grass-covered slopes, also on slopes which were bare of snow prior to the current snowfall.
Snowpack
Renewed snowfall is about to set in, the fresh snow will be transported by strong-velocity westerly winds and widespread new snowdrift accumulations will be generated above the treeline. These will be deposited atop loose fresh snow. Inside the drifts, layers of graupel will be deposited over far-reaching areas. At intermediate altitudes the fresh snow will often be deposited on wet ground which was previously bare of snow and is moist from below. Snow is beginning to glide over smooth ground.
Tendency
Due to wind and new fallen snow avalanche danger will remain tense.

Daytime increase in avalanche danger due to fresh snow and wind
Avalanche danger during the morning will be moderate above 2200m, below that altitude danger is low. With increasing amounts of fresh fallen snow, avalanche danger above 2200m will rise to CONSIDERABLE. Avalanches can in some zones be triggered by one sole skier, esp. in the afternoon, and grow to medium size. Danger zones occur in the old snow on north-facing slopes above 2200m, in all aspects above 2400m. Fresh snowdrift accumulations occur both near to and distant from ridgelines, behind protruberances in the terrain, and in gullies and bowls. Particularly below 2000m the old snowpack is thoroughly wet and small-to-medium wet-snow avalanches are possible. Avalanches in high altitudes can sweep along more deeply embedded layers of the snowpack and in isolated cases plummet all the way down to the green zones. Small-to-medium glide-snow avalanches can trigger naturally in very to extremely steep grass-covered terrain.
Snowpack
By Saturday evening 30cm of fresh snow is anticipated at high altitudes. Above 2200m on north-facing slopes weak layers of faceted crystals are found in the lowermost part of the snowpack. Above 2400m on W/S/E facing slopes there are faceted crystals between crusts. Inside the snowdrifts, in addition, trigger-sensitive layers can form rapidly. Below 2000m the snowpack will forfeit its firmness on Friday night due to rainfall and water seepage.

Fresh snowfall and strong-to-stormy northerly winds generated new snowdrift accumulations esp. in gullies and bowls, behind protruberances in the terrain which can be triggered in the old snow and reach medium size, particularly in wind-protected zones. Even one sole skier can trigger avalanches. Danger zones occur esp. on W/N/E-facing slopes above 2300m. Very isolated danger zones occur also on south-facing slopes above 2600m. In isolated cases, avalanches can sweep along more deeply embedded layers of the snowpack. Danger zones and likelihood of triggering will increase during the course of the day. In addition, avalanches can trigger in the near-surface layers even by one sole skier, esp. in the afternoon in the wind-impacted zones.

Along the Salzburg border, 20-30cm of fresh snow was registered, by morning another 10-15cm is anticipated. The often storm-strength winds will transport the snow, the freshly generated snowdrift accumulations above 2200m will be deposited atop an unfavorable old snowpack surface.

Wet loose-snow and glide-snow avalanches in very steep terrain are the main danger
Avalanche danger is low. Isolated small loose-snow naturally triggered avalanches are possible or can be triggered by one sole skier. Danger zones for small slab avalanches in the snowdrifts occur seldom on very steep north-facing slopes at high altitudes. On steep grass-covered slopes, isolated small glide-snow avalanches are possible. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall demand adequate consideration.small wet loose-snow avalanches are possible in very-to-extremely steep terrain in all aspects. The gliding snow activity will increase, small-to-medium glide-snow avalanches are possible on steep grass-covered slopes. Above 2300m, only few danger zones where still small dry slab avalanches can be triggered. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall demand adequate consideration.
Snowpack
The snowpack cools at night and forms a melt-freeze crust which is usually capable of bearing loads. During the daytime the snowpack then softens and forfeits its bonding. On shady slopes at high and high-alpine altitudes there are several weak layers of facted crystals inside the old fundament. At high altitudes the old snowpack fundament is poor on shady slopes but the requisite slab is lacking.
Tendency
Dense clouds at night, the snowpack can hardly cool. Snowfall will set in. Avalanche danger will increase during the course of the day.

Caution: trigger-sensitive fresh snow at high altitudes. Receding danger of wet avalanches due to reduced precipitation.
From zones which have not yet discharged, further wet loose-snow avalanches can be expected, also medium-sized releases. In addition, isolated small-to-medium wet slab avalanches are possible at the foot of rock walls. Runout zones of wet-snow avalanches should be avoided. Naturally triggered wet-snow avalanches will decrease as rainfall comes to an end. Above 1700m, fresh fallen snow and drifts are prone to triggering, one sole skier can trigger avalanches esp. in gullies and bowls in the zones which are much wind-impacted. Avalanches can in isolated cases fracture down to more deeply embedded layers of the snowpack and then lengtrhen the runout zones. Due to solar radiation, increasingly frequent loose-snow avalanches can be expected during the course of the day, mostly small-sized releases in case of extensive bright intervals.
Naturally triggered small-to-medium wet avalanches will increase as rainfall sets in. On extremely steep slopes, small-to-medium wet loose-snow avalanches can be expected. Particularly at the foot of rock walls, small-to-medium wet slab avalanches are possible. Runout zones of wet-snow avalanches should be avoided. Above 1900m: lots of fresh snow expected which will be prone to triggering, also the freshly generated snowdrift accumulations, esp. in gullies and bowls in zones with wind impact. Avalanches can in isolated cases sweep along the thoroughly wet snowpack, which then lengthens the runout zone of the plummeting snow masses.

Rainfall will make the snowpack thoroughly wet, esp. below 1700m. Above 1700m, 30-40cm of fresh snow has been registered. By morning, another 10-20cm is expected. The fresh fallen snow is prone to triggering. In the lowermost part of the snowpack on N/W/E-facing slopes, faceted expansively metamorphosed weak layers threaten.
The avalanche is above the treeline considerable and below that low. Snowdrift accumulations are forming danger spots which are increasing with height. They are found especially in the expositions west via east till south. They can be triggered by small additional loads as slab avalanches. In places avalanches can be triggered within the old snow in high shady areas. Spontaneous gliding- or wet loose-snow avalanches coming from steep smooth slopes are possible.
Snowpack
Fresh snowdrift accumulations are placed on top of an old snow cover with which it is often sufficiently bonded. Soft layers within the fresh cover or in shady slopes within the old snow near the surface can function as weak layers. On Sunday around 30 cm new snow is called which will form - due to strong wind influence - unevenly amounts of snowdrift accumulations. In places rain respectively wetness from the ground leads to a loss of moisture within the snowcover.
Tendency
On Monday the temperatures will fall and the snowline will be around 900 m. Precipitation, predominantly in Nordstau areas are dominating. Partially stormy northern winds. Snowdrift problem is increasing due to higher amounts of new snow! On Monday the temperatures will fall and the snowline will be around 900 m.

Daytime increase in avalanche danger. In high-alpine regions: beware hidden weak layers.
Daytime warming and solar radiation lead to increasing avalanche danger during the course of the day. In early morning, danger above 2300m is moderate, below that altitude danger is low. During the daytime it rises at all altitudes to moderate. Below 2400m, increasingly frequent small-to-medium wet-snow avalanches are possible in as aspects on steep slopes.
