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.

Avoid snowdrift accumulations on north-facing slopes
Avalanche danger above 2000m is moderate, below that altitude danger is low. Slab avalanches can be triggered by one sole skier and in unfavorable circumstances reach medium size where snow is sufficient or if fractures down to more deeply embedded layers occur. 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 steel gullies and bowls. During the course of the day, naturally triggered loose-snow avalanches (mostly Danger Level 1) 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.
Snowpack
Settled fresh snow and older snowdrifts have been deposited on steep shady slopes atop an expansively metamorphosed snowpack which is prone to triggering in places, since it evidences a weak layer. Weak layers in the lowermost part of the snowpack are no longer likely to trigger. 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.
Tendency
No significant change expected. On sunny slopes, springtime conditions. On shady slopes, avoid snowdrifts.
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.

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.

Danger of falls on frozen snowpack surface
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
At high altitudes, shallow snowdrifts have accumulated, lie deposited atop facetec, expansively metamorphosed surface 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 turns to firn snow and the snowpack becomes softer.
Tendency
Avalanche danger not expected to change significantly
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.

During the course of the day on sunny slopes increasing moist loss. On shady slopes danger spots due to snowdrift.
Avalanche danger is in general low. During the course of the day loose wet-snow avalanches which could be triggered in extremly steep, rocky slopes can be sponaneously triggered. These avalanches are mostly small sized. Occasionaly fresh snowdrift deposits in high altitudes on shady slopes and adjaecent to ridgelines could be triggered as small slab avalanches.
Snowpack
During the nicht 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 in hight altitudes loose snow is found in some places, and in rare cases fresh snowdrift deposits which are prone to triggering have formed due to southern winds. The snow surface is often icy or hoar-like. The snow base is predominantly stable. Especially on sunny slopes only little amounts of snow is found even in high altitudes.
Tendency
On Sunday sunny weather is called with high veil clouds. The southern winds are increasing in some places but it will stay mild. The avalanche danger will stay low.

In the morning hours favorable conditions. Caution: daytime warming.
Predominantly favorable conditions prevail in the morning hours, with low avalanche danger. Due to daytime warming and solar radiation, moist slides and small wet-snow avalanches are possible esp. on steep sunny slopes, including more frequent medium-sized releases. Isolated danger zones occur at high altitudes esp. on shady ridgeline steep slopes, they can trigger small slab avalanches in steep shady 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.
Snowpack
At high altitudes on shady slopes, isolated near-surface weak layers are evident, prone to triggering. On higher-altitude shady slopes the uppermost layers of often still powdery. At night on sunny slopes and at lower altitudes, a melt-freeze crust forms, which then softens up during the daytime, often breakable crusts. The below-average old snowpack is well consolidated all in all. With rising temperatures and solar radiation, the snowpack is moistening down to intermediate altitudes, and as it becomes wetter, it becomes weaker.

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 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.

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 2400m. 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
No significant change anticipated. On sunny slopes, springtime conditions. On shady slopes, avoid snowdrifts.
