Caution urged towards wet snow and weak layers in old snow.

Small wet loose-snow avalanches are possible, esp. on steep slopes. In addition, isolateed small-to-medium wet slab avalanches are possible at the foot of rock walls, esp. during the afternoon hours, in starting zones which have not yet discharged. Weak layers in the old snowpack can in isolated cases be triggered by one sole skier. Such danger zones occur on very steep shady slopes and in transitions into gullies and bowls above 1900m, and can reach medium size. Due to fresh fallen snow and moderate-velocity southerly winds, mostly small snowdrift accumulations were generated in ridgeline terrain, often triggerable by minimum additional loading.

Snowpack

dp.10: springtime scenario
dp.1: deep persistent weak layer

Nocturnal outgoing longwave radiation is reduced. The snowpack will soften increasingly during the course of the day. In the middle part of the snowpack on N/W/E facing slopes there are faceted, expansively metamorphosed weak layers evident. Snowdrift accumulations lie deposited atop unfavorable layers, esp. above 2300m on shady slopes.

Caution: wet snow and 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 isolated glide-snow avalanches can be expected, mostly small releases.

Snowpack

Due to reduced nocturnal outgoing longwave radiation the snowpack surface can hardly cool and rapidly softens in the early morning hours. The snowpack is moist in all aspects up to high altitudes. 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.

Little change expected

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

On extremely steep slopes, mostly small wet loose-snow avalanches can be expected. In addition, during the afternoon hours, mostly small wet slab avalanches are possible, esp. at the foot of rock walls on sunny slopes below 2600m and on shady slopes below 2200m. Weak layers in the old snowpack can in isolated cases be triggered by one sole skier. Such danger zones occur on N/W/E facing slopes above 2200m. Very isolated danger zones occur on sunny slopes above 2600m, and can reach medium size. Due to fresh snow and moderate-velocity northerly winds, mostly small snowdrift accumulations will be generated, often triggerable by minimum additional loading.

Moderate avalanche danger due to rain. Spontaneous wet loose-snow avalanches coming from steep areas are increasing

The avalanche danger increases from low to medium moderate during the course of the day. Due to soaking (rain, sunradiation) small moist and wet avalanches are more possible. Danger spots are found especially in full steep gullies, bowls and slopes. Weak layers within the old snow can be triggered with high additional loads in very few places and lead to small sized slab avalanches. Danger spots are located in very steep shady slopes above 2.000 m. The amount of danger spots increases with altitude.

Snowpack

Clouds and limited radiation during the night lead to increasing soaking of the snow cover and the setteling process of the snowcover is limited. Additional soaking due to rainshowers and sun radiation and snow melting lead to destabilization of the snow cover below 2.000 m. In steep shady slopes above 2.000 m weak layers of faceted snow are found within the snow base.

Tendency

On Thursday the winds will get stronger and the weather will be dry during the course of the day and partially sunny. No significant change of the avalanche danger.

Small-area snowdrifts at high altitudes: caution

On shady steep high-altitudes slopes and in ridgeline terrain, small-area snowdrift accumulations require caution. 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. Near-surface weak layers, esp in little-tracked terrain on shady steep slopes, are often still prone to triggering. On steep grass-covered slopes with sufficient snow, isolated medium-sized glide-snow avalanches still possible.

Snowpack

Fresh snowfall is expected (5-10cm) which will be deposited up to high altitudes atop a moist old snowpack surface, it will bond well. In ridgeilne terrain, small drifts will be generated. Below 1500m there is little snow on the ground. On shady slopes at high and high-alpine altitudes the older drifts lie atop an unfavorable old snowpack, which has increasingly stabilized.

Tendency

Glide-snow avalanches still possible, despite lower temperatures

Not much snow, low avalanche danger

Avalanche danger is low. In isolated cases, small loose-snow avalanches can trigger naturally 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 caution. Small glide-snow avalanches are possible on steep slopes on smooth ground where there is sufficient snow.

Snowpack

The shallow snowpack is moist up to summit level, often wet. Gliding movements over wet, smooth ground are possible. A cohesive, area-wide snowpack is generally only evident on shady slopes above 1400m. It is well consolidated by and large. South-facing slopes are largely bare of snow on the ground.

Tendency

Avalanche danger levels expected to remain unchanged

Wet loose-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.

Snowpack

Due to reduced nocturnal outgoing longwave radiation the snowpack surface can hardly cool and rapidly softens in the early morning hours. The snowpack is moist in all aspects up to high altitudes. At high altitudes the old snowpack fundament on shady slopes is often poor, but the requisite slab is lacking.

Tendency

Little change expected

Beware wet snow

On extremely steep slopes, generally small-sized wet loose-snow avalanches can be expected. In addition, during the afternoon hours, mostly small wet slab avalanches are possible. Weak layers in the old snowpack can in isolated cases be triggered by one sole skier. Isolated danger zones occur on very steep shady slopes, esp. above 2000m. In addition, small snowdrift accumulations require caution, they can be triggered by one sole skier in isolated cases.

Snowpack

dp.10: springtime scenario

Nocturnal outgoing longwave radiation is reduced. The snowpack will soften increasingly during the course of the day. In the lower part of the snowpack on shady slopes there are faceted, expansively metamorphosed weak layers evident. Beneath the timberline there is only little snow on the ground.

Danger level


Avalanche Problem
Wet snow


Avalanche danger is low. Wet snow can be problematic. Isolated small loose snow avalanches can trigger naturally in extremely steep terrain. Isolated small glide-snow avalanches cannot be ruled out on steep, smooth slopes.

Snowpack

Up to summit levels the snowpack is moist, sometimes wet, which is intensified by rainshowers. 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. In some places a few centimeters of loose snow are expected to fall above 1600m.

Tendency

No significant change of avalanche danger anticipated.
