Due to brisk W/NW winds, snowdrift accumulations will be generated esp. in high-altitude ridgeline and pass areas which are prone to triggering (but small). Danger zones tend to increase in frequency with ascending altitude. Older snowdrift accumulations are often still prone to triggering, can be released by one sole skier and reach medium size. Snowdrift accumulations in steep terrain should be evaluated with great caution. The danger of small, in isolated cases medium-sized glide-snow avalanches is still difficult to assess. Caution urged below glide cracks.
Snowpack
The W/NW winds will transport the loose snow over the course of the day. Fresh and older snowdrift accumulations are often prone to triggering. Esp. on shady slopes, in wind-protected zones at high altitudes and on east-facing slopes, the snowdrifts have been deposited atop a loosely-packed snowpack surface. On sunny slopes the fresh snow is already bonded.
Tendency
Avalanche danger levels will slowly recede.

Assess with caution the fresh snowdrift accumulations
Avalanche danger above 2000m is moderate, below that altitude danger is low. Freshly generated snowdrift accumulations can in some places be triggered by one sole skier as a slab avalanche. Releases tend to be small-sized. Danger zones occur esp. near ridgelines, behind protruberances in the landscape and in gullies and bowls, usually they are easy to recognize. On very steep shady slopes, weak layers can fracture and be swept along. Caution urged esp. at entry points into very steep gullies and little skied-on north-facing slopes. On extremely steep slopes, small loose-snow avalanches can be expected. Isolated small naturally triggered glide-snow avalanches are possible.
Snowpack
Atop a hardened crust (or else, bare ground) 10-30 cm of loosely-packed snow lie deposited, often wind impacted. On shady slopes at high altitudes the fresh snow from Friday has also been deposited atop loose snow or surface hoar.

Caution: freshly generated snowdrift accumulations. Avalanche danger at upper part of Level 2 (Moderate) in regions with lots of wind
Due to fresh snow and moderate northerly winds, often trigger-sensitive snowdrift accumulations have been generated in ridgeline terrain, gullies and bowls. These drifts can be triggered in many cases by one sole skier in all aspects above 1800m. Danger zones are easily recognized to the practiced eye. In morning, likelihood of triggering increases somewhat. Due to solar radiation, increasingly frequent small loose-snow avalanches can be expected, esp. on steep rocky slopes. The runout zones require adequate consideration. In addition, isolated avalanches can trigger in the weak old snow, esp. on W/N/E facing slopes above 2200m. Caution urged in transitions from shallow to deep snow, e.g. at entry points into gullies and bowls. Caution in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls. Avalanches can reach medium size.
Snowpack
dp.6: cold, loose snow and wind dp.4: cold following warm / warm following cold
Fresh snow (10-20cm) was registered widespread. Strong velocity winds transported the fresh snow, fresh drifts accumulated at high and high-alpine altitudes and were deposited on top of an unfavorable old snowpack surface. In the lower part of the snow cover, particularly on W/N/E facing slopes, there are faceted, expansively metamorphosed weak layers evident. As of midday, solar radiation will lead to a moistening of the snowpack on very steep sunny slopes below 2800m.
Tendency
Fresh snowdrifts need to be cautiously assessed. Pay attention to weak layers in old snowpack.

Hidden persistent weak layer problem
Avalanche danger above 2200m is moderate, below that altitude danger is low. In few places, an avalanche can be triggered by one sole skier as a slab avalanche. Danger zones are nearly impossible to recognize, most critical behind protruberances in the landscape and in gullies and bowls. Fresh drifts on some ridgeline slopes can be easily triggered as a small slab. The wind-loaded zones are easily recognized, watch out for the risks of falling. On very steep sunny slopes, small loose-snow avalanches are possible. Isolated small naturally triggered glide-snow avalanches are possible.

Favorable situation
Avalanche danger is low. Triggering a small slab is possible in only few places, most endangered are shady slopes in very steep terrain above 2000m. In isolated cases a small glide-snow avalanche is possible. Isolated small naturally triggered glide-snow avalanches possible.
Snowpack
Atop a hardened crust (or else, bare ground) 10-15 cm of loosely-packed snow lie deposited. The fundament on shady steep slopes is often weak, but the weak layer is varied and the slab shallow.

Danger level
No significant change of the avalanche danger. Caution: snowdrift accumulations in shady areas!
Still low avalanche danger. Dander spots can be located in high altitudes in the expositions north to east and behind ridgelines. There slab avalanches could be triggered in extremly steep slopes by high additional loads.
Snowpack
The new snow could settle due to sun radiation. In high altitudes small amounts of snowdrift accumulations have formed which partially are on top of faceted snow. The new snow is covering an old snow cover which weakened due to kinetic metamorphosis in high altitudes it is on top of a hard old snow cover.
Tendency
The avalanche danger is not significantly changing. Monday morning starts with dense clouds and some snowfall. During the course of the day it clears up and it can be sunny in some regions. In the western part of upper Styria it will clear up sooner.
