Danger level

Wet snow
Persistent weak layer		1900m

Rising danger of moist/wet avalanches due to rainfall. Attention: weak layers in old snow.

Due to rainfall, increasingly frequent moist/wet-snow avalanches are possible, esp. on steep slopes in all aspects below 2000m. Releases are relatively small and can be triggered in the old snow even by one sole skier. Such danger zones lie on very steep shady slopes and in transitions into gullies and bowls above 1900m on steep N/W/E facing slopes and in gullies and bowls and can reach medium size.

Snowpack

More rainfall was registered than expected, but more is still expected, along with some snowfall esp. at high altitudes. Nocturnal outgoing longwave radiation is nearly absent. The snowpack is moist. In the lowermost part of the snowpack there are faceted, expansively metamorphosed weak layers evident, esp. above 2000.

Moist/wet-snow avalanches still possible. Caution urged towards weak layers in old snow.

Due to rainfall and the snowpack which is becoming thoroughly wet, increasingly frequent moist/wet-snow avalanches are possible, esp. on steep slopes in all aspects below 2000m. Releases are relatively small and can be triggered in the old snow even by one sole skier. Such danger zones lie on very steep shady slopes and in transitions into gullies and bowls above 2000m on steep N/W/E facing slopes and in gullies and bowls and can reach medium size. In addition, small snowdrifts accumulations require attentiveness, esp. at high altitudes.

Snowpack

Heavy snowfall (up to 20cm) over 2000m, some rainfall, more is expected esp. at high altitudes. Nocturnal outgoing longwave radiation is nearly absent. The snowpack is moist. In the lowermost part of the snowpack there are faceted, expansively metamorphosed weak layers evident, esp. at high altitudes. In the middle part of the snowpack on N/W/E facing slopes there are facted weak layers, esp. above 2000m. Due to fresh snowfall and moderate-to-strong velocity southerly winds, small snowdrift accumulations will be generated esp. in ridgeline terrain.

Beware wet snow and weak old snow

Danger level

2300m

Persistent weak layer		2300m
Wet snow		2300m

Wet-snow problem up to high altitudes. Above 2300m: hidden persistent weak layer.

Avalanche danger is moderate. Dry-snow slab avalanches can be triggered by one sole skier above 2300m, the fresh snowdrifts have been deposited also distant from ridgelines in gullies and bowls, avalanches can reach medium size and fracture down to more deeply embedded layers in the snowpack esp. on little-tracked steep north-facing slopes. Small-to-medium moist and dry-snow naturally triggered slab avalanches are possible below 2300m. Wet-snow avalanches in extremely steep terrain and isolaated glide-snow avalanches can be expected, mostly small release (loose-snow, slabs gliding over the ground atop a melt-freeze crust).

Snowpack

On shady slopes at high and high-alpine altitudes the freshly generated foehn-induced drifts lie deposited atop an unfavorable snowpack surface. Inside the old snowpack are several weak layers of faceted crystals which can serve as a slab atop the fresh snowdrifts. Also on sunny slopes, moist slabs can slide away over the uppermost crusts of the old snowpack. Due to reduced nocturnal outgoing longwave radiation and solar radiation during daytime hours, the snowpack is at least moist up to 2300m and is rapidly forfeiting its firmness.

Tendency

Likelihood of the snowdrifts triggering will gradually decrease, wet-snow problem and persistent weak layer will continue.

Danger level

1500m

Gliding snow		1500m
Wet snow

Circumvent glide cracks!

Avalanche danger is moderate above 1500m, below that altitude it is low. Gliding snow is the main problem. On very steep slopes in all aspects, wet glide-snow avalanches can release naturally over smooth ground, releases are mostly small sized. In addition, small wet loose-snow avalanches can trigger naturally in extremely steep terrain. l

Snowpack

Moistening of the snowpack progresses. At the ground the snowpack is wet wide-spread, therefore, it starts gliding over smooth ground. Otherwise it is mostly stable. Patches with dry snow at the surface are becoming rare, these are now only found on shady highest altitude slopes. In isolated cases there is a weak layer near the ground. Small snowdrifts have accumulated close to ridges. In south aspects, the snowpack has become patchy even at high altitude.

Tendency

Danger of dry avalanches can increase somewhat.

Fresh snowdrifts at high altitudes, wet avalanches during daytime

Due to daytime warming and often diffuse radiation, mostly small-sized wet-snow avalanches are possible in steep terrain. On steep grass-covered slopes where there is sufficient snow, in addition, danger of small, in isolated cases medium-sized glide-snow avalanches threatens. On shady high-altitude slopes, mostly small snowdrift accumulations are prone to triggering in isolated cases. One sole skier can trigger a small slab avalanche in these zones. 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.

Snowpack

Nighttime hours initially will have good outgoing longwave radiation, later on it will be reduced due to heavy cloud. Especially on sunny slopes the uppermost layers will moisten during the daytime hours due to diffuse radiation and low-lying clouds. In addition, rainfall at intermediate altitudes will weaken the snowpack. were foehn-impacted and warm, often reducing outgoing longwave radiation so that only a breakable crust could form. In addition, light rainfall up to intermediate altitudes. Below 1500m there is little snow on the ground. Shady slopes at high and high-alpine altitudes were impacted by strong-velocity foehn winds over the weekend, the newly generated snowdrifts were deposited atop an unfavorable old snowpack surface.

Caution: weak layers in the old snow, fresh snowdrifts at high and high-alpine altitudes

Weak layers can be triggered in the old snow even by one sole skier. Such danger zones lie on N/W/E facing very steep shady slopes and in transitions into gullies and bowls above 2200m. Very isolated danger zones also occur on very steep sunny slopes above 2600m. Avalanches can in isolated cases reach medium size. In addition, fresh snowdrift accumulations require attentiveness, esp at high and high-alpine altitudes. Due to snowpack moistening, isolated moist loose-snow avalanches are possible, esp. on very steep slopes, small releases.

Snowpack

dp.1: deep persistent weak layer
dp.6: cold, loose snow and wind

5-10cm fresh snow was registered, and some rainfall. More snowfall is anticipated, esp. at high altitudes. In the middle part of the snowpack on N/W/E facing slopes there are faceted weak layers, esp above 2200m. Due to fresh snowfall and moderate-to-strong velocity southerly winds, small snowdrift accumulations were generated esp. in ridgeline terrain. Nocturnal outgoing longwave radiation hardly exists, which leads to increasing moistening of the snowpack esp. below 2200m.

Fresh snowdrifts at high altitudes, wet avalanches during daytime

Fresh snowdrift accumulations have been generated this weekend which are often prone to triggering. One sole winter sports enthusiast can trigger mostly small slab avalanches in these zones. 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. Less danger on steep grass-covered slopes with sufficient snow, isolated medium-sized glide-snow avalanches still possible. With daytime warming and solar radiation, small-to-medium wet-snow avalanches are possible in steep terrain.

Wet snow

Danger spots due to persistent weak layers (on shady slopes). Wet loose-snow avalanches in all expositions.

The avalanche danger is in general low. Nevertheless some danger spots exist. There medium-sized slab avalanches can be triggered by high additional loads. Especially in entries to steep shady gullies and bowls and slopes above 2.000 m. The amount of danger spots increases with altitude. Spontaneous wet-snow avalanches in all expositions are possible.

Snowpack

der snowdrift deposits are placed on a weak snowbase in shady high areas. Apart of that the snowcover could mostly stabilize due to warming. The snow base itself is formed of faceted snow and realtively soft. The upper layer does not freeze during the nights and rain showers lead to destabilization. This can cause spontaneous avalanches.

Tendency

Ther stays changeable and mild with unproductive rainshowers. The avalanche danger stays low.

Danger of falling outweighs that of being buried in snow masses

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 N/E facing slopes at high altitudes. On steep grass-covered slopes, isolated small glide-snow avalanches are possible.

Snowpack

The shallow, generally stable snowpack has consolidated well. On shady slopes, thin fresh snowdrift accumulations are being generated. Due to reduced nocturnal outgoing longwave radiation and often diffuse radiation the snowpack is superficially moist and forfeiting its firmness.

Avalanche danger is low. Wet snow can be problematic. Isolated small loose snow avalanches can trigger naturally in extremely steep terrain.

Snowpack

Up to the summits the snowpack is now moist, partly even wet. Possibility of gliding movements over wet smooth ground. Otherwise the snowpack is mostly stable. Only on shady side slopes above approx. 1300m you will now still find a cohesive snow cover. Regionally, south-facing terrain is almost completely bare.
