Isolated avalanches are triggerable by persons in the weak old snow, esp. on W/N/E facng slopes above 1800m and at the foot of rock walls, releases sometimes medium-sized. Due to daytime warming and solar radiation, isolated small wet loose-snow avalanches are possible, esp. on very steep sunny slopes.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
W/N/E facing slopes: in the lowermost part of the snowpack are expansively metamorphosed (faceted) weak layers, esp. above 1800m. Due to low temperatures and low air moisture, the surface forms a crust during nighttime hours. Sunshine and warmth during daytime hours soften up the snowpack.
Tendency
Widespread precipitation is anticipated, snowfall level at high altitudes.

Avoid snowdrift accumulations on north-facing slopes
Avalanche danger above 2000m is moderate, below that altitude danger is low. Small to medium slab avalanches can be triggered by one sole skier. Danger zones occur esp. on NW/N/E facing slopes, esp. near ridgelines on occasion distant from ridgelines. Caution urged esp. at entry points into very steep gullies and bowls. During the course of the day, naturally triggered loose-snow avalanches can be expected in extremely steep south-facing terrain below 2800m. On steep grass-covered slopes, isolated small glide-snow avalanches are possible in isolated cases. On steep grass-covered slopes isolated small glide-snow avalanches are possible.
Snowpack
In foehn-exposed areas, trigger-sensitive snowdrifts lie deposited at high altitudes on steep shady slopes atop expansively metamorphosed old snowpack layers. On sunny slopes there forms a thin melt-freeze crust at night - sometimes capable of bearing loads - which softens during the daytime, becomes moist, and can forfeit bonding.
Tendency
On Sunday night, clouds will move in, only limited gain in snowpack firmness on south-facing slopes. Above 2000m a bit of fresh snow is expected, further down light rainfall, which will heighten the wet/gliding snow problem.

Beware falls on hardened snowpack surfaces.
Avalanche danger is low. Wet snow can be problematic. On extremely steep sunny slopes, isolated small wet loose-snow avalanches can trigger naturally. At intermediate altitudes esp. on E/W facing slopes, at high altitudes on south-facing slopes, where the moisture reaches ground level, small glide-snow avalanches cannot be ruled out on steep grass-covered slopes.
Snowpack
On sunny slopes the ground is bare of snow up to high altitudes. The remains of the snowpack are melt-freeze encrusted in early morning. Due to solar radiation, bonding disperses in near-surface snow, it turns to firn snow and the snowpack becomes more and more moist/wet. On shady slopes, isolated snowdrift patches can be prone to triggering. Elsewhere there is dry powder atop a compact snowpack. On shady slopes where snow is shallow, isolated layers of faceted crystals have persisted inside the snowpack. Tests confirm that the snowpack is stable.
Tendency
Avalanche danger not expected to change significantly. As clouds move in, snow will moisten thoroughly also on shady slopes at intermediate altitudes (due to some rainfall).

In high altitudes danger spots are found in some places
Avalanche danger is in general low. In high altitudes danger spots in form of snowdrift deposits which are prone to triggering are found. There - in shady areas or adjacent to ridgelines small slab avalanches can be triggered. In extremely steep slopes on sunny areas spontaneous loose-snow avalanches can’t be ruled out. Ridgelines and summits are icy and hard. Be aware of risk of falling.
Snowpack
During the night the snow cover cools down and solidifies. Due to radiation the snow will get firn-like already in the morning and gets increasingly moist and instable. On shady slopes above 2.000 m loose snow is found in some places, and in rare cases thin snowdrift deposits which are prone to triggering have formed. The snow base is predominantly stable. Especially on sunny slopes only little amounts of snow is found even in high altitudes.
Tendency
Monday morning dense clouds and rain up to 2.000 m is forecasted. In the afternoon it will clear up and sunny for the east is called. In the west low altitude clouds can persist. The avalanche danger will stay low.

In the morning hours favorable conditions. Caution: daytime warming.
On Sunday in foehn lanes, strong-to-stormy high altitude winds will arise, esp. on north-facing slopes small snowdrift accumulations will be generated. Isolated triggerings of small avalanches can be released by persons in extremely steep terrain. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate consideration. Due to warmth and solar radiation, moist slids and small wet-snow avalanches are possible esp. on steep sunny slopes during the course of the day. On steep grass-covered slopes with ample snow or on smooth ground, increasingly frequent small glide-snow avalanches are possible.
Snowpack
Storm strength southerly foehn winds will generate trigger sensitive snowdrift accumulations at high altitudes. Due to mild temperatures, near-surface layers will lose their firmness and the snowpack will moisten/become wet down to intermediate altitudes, weakening further. At high altitudes on shady slopes the upper layers are often still powdery. Overnight on sunny slopes and at lower altitudes, a melt-freeze crust forms, often breakable crusts. With daytime warming, the snowpack forfeits its firmness and becomes weaker as it becomes wetter. The below-average snowpack is all-in-all well consolidated.
Tendency
As clouds move in on Sunday night, the snowpack surface may consolidate somewhat. Below 1800m light rainfall will weaken the snowpack.

Generally favorable avalanche situation, only few danger zones
Avalanche danger is low. Isolated danger zones occur near ridgelines, esp. in steep shady terrain at summit level. 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. During the course of the day, small loose-snow slides continue to be possible. On steep grass-covered slopes, isolated small glide-snow avalanches are possible.
Snowpack
On shady slopes at high altitudes, isolated weak layers in transitions from old to fresh snow. On sunny slopes and at lower altitudes the bonding of fresh snow to old snow is generally good, the snowpack is often moistened and forms a thin melt-freeze crust during the night. During the course of the day, this crust softens, the surface becomes moist and can forfeit its bonding.
Tendency
On Sunday night, clouds will move in, only limited gain in snowpack firmness on south-facing slopes. Above 2000m a bit of fresh snow is expected, further down light rainfall, which will heighten the wet/gliding snow problem in Lungau and Tauern.
Danger level
Favorable avalanche situation
Isolated avalanche prone locations occur on very steep shady slopes and in transitions into gullies and bowls at high altitudes. Avalanches can hardly trigger and releases are small-sized. Due to daytime warming and solar radiation only isolated small wet loose-snow avalanches are possible, esp. on very steep sunny slopes.

Generally favorable avalanche situation, isolated danger zones on shady slopes
Avalanche danger is low. Freshly generated snowdrift accumulations can be trigger a small slab avalanche in steep terrain by one sole skier and reach medium size where snow is sufficient. Danger zones occur esp. on NW/N/E facing slopes above 2000m. Danger zones often blanketed, making them difficult to recognize. Caution especially at entry points into very steep gullies and bowls. During the course of the day, naturally triggered loose-snow avalanches are possible in all aspects, esp. in extremely steep south-facing terrain below 2800m, releases will be generally small-sized. On steep grass-covered slopes, very isolated small glide-snow avalanches are possible.
Snowpack
The settled fresh snow has been deposited on steep shady slopes above 2400m atop an expansively metamorphosed snowpack which is prone to triggering in places. On sunny slopes and at lower altitudes, the bonding of fresh fallen snow to the old snowpack is generally good, the surface moistens during the daytime, forms a thin melt-freeze crust at night - not capable of bearing loads - and can forfeit bonding. The crust softens up during the daytime, the snowpack becomes superficially moist, forfeits its bonding.
Tendency
On Sunday night, clouds will move in, only limited gain in snowpack firmness on south-facing slopes. Above 2000m a bit of fresh snow is expected, further down light rainfall, which will heighten the wet/gliding snow problem, esp. in the Tauern.

Caution: small snowdrift accumulations at high altitudes
Avalanche danger is low. At high altitudes, small-area snowdrift accumlations can be prone to triggering as slab avalanches even by one sole person, esp. on very steep ridgeline terrain on NW/N/E facing slopes. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. On extremely steep sunny slopes, in addition, isolated small wet loose-snow avalanches can release during the course of the day. On steep grass-covered slopes, small glide-snow avalanches cannot be ruled out.
Snowpack
At high altitudes, shallow snowdrifts have accumulated, lie deposited atop faceted, expansively metamorphosed surfaces and are poorly bonded with them. On shady slopes where snow is shallow, isolated layers of faceted crystals persist more deeply embedded inside the snowpack, but they are unlikely to trigger. On sunny slopes the ground is bare of snow up to high altitudes. The remains of the snowpack are melt-freeze encrusted in early morning. Due to solar radiation, bonding disperses in near-surface snow, it becomes soft.
Tendency
Avalanche danger not expected to change significantly. As clouds move in, snow will moisten thoroughly also on shady slopes at intermediate altitudes (due to some rainfall).
Danger level
Caution: weak layers in old snow and freshly generated snowdrifts.
Due to light-to-moderate southerly winds, fresh snowdrift accumulations have been generated esp. in ridgeline terrain. The fresh drifts are small but often prone to triggering, esp. a high altitudes, releases can reach medium size, particularly on W/N/E facing slopes and at the foot of rock walls at high altitudes. Due to daytime warming and solar radiation, increasingly frequent generally wet loose-snow avalanches are possible, esp. on extremely steep sunny slopes.
