Caution: wet snow problem persists. In high-alpine regions, caution urged towards hidden weak layers and fresh drifts.
Avalanche danger is moderate. Wet-snow avalanches can be triggered by one sole skier on steep slopes in all aspects in steep sunny terrain which has not yet discharged. Small-to-medium glide-snow avalanches can trigger naturally on extremely steep grass-covered slopes. Above 2300m, dry slab avalanches can still be triggered by one sole skier. Danger zones occur on very steep, little-tracked slopes on NW/NE facing slopes. Avalanches can fracture down to more deeply embedded layers in the snowpack and reach medium size. Small freshly generated snowdrift patches are often prone to triggering, esp. on very steep shady slopes in high-alpine ridgeline terrain. 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. 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.
Tendency
Little change expected. Strong solar radiation and slight rise in daytime temperatures will increase the wet-snow problem at high and high-alpine altitudes.

Caution in little-tracked shady steep terrain. Beware small snowdrifts.
Near-surface weak layers are often still prone to triggering, esp. on little-tracked steep shady slopes. On shady steep high-altitude 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. On steep grass-covered slopes with sufficient snow, isolated medium-sized glide-snow avalanches still possible.
Snowpack
Fresh snowfall is expected (5cm) which will be deposited up to high altitudes atop a weak old snowpack surface, it will bond well. In high-altitude 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 are often still prone to triggering.

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
Showers will bring only minor new snowfall which will bond well with the moist old snowpack. On shady steep high-altitude slopes and in ridgeline terrain, small-area snowdrift accumulations require caution. A cohesive area-wide snowpack is generally evident only on shady slopes above 1400m. Up to high altitudes the snowpack is most and weakened by rainfall. Gliding movement over smooth ground are possible. South-facing slopes are generally bare of snow.

Friday will be very sunny. Avalanche danger levels expected to remain unchanged.

Avoid zones below glide cracks.
Avalanche danger above 1500 m is moderate, below that altitude danger 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. Avalanches tend to be small-sized, but can grow to medium size in isolated cases. In addition, small wet loose-snow avalanches can trigger naturally in extremely steep terrain. Small dry slab avalanches can only be triggered in isolated cases on steep high altitude slopes adjacent to ridgelines in N/E aspects.
Snowpack
At intermediate altitudes the small quantities of snow are completely soaked. In many places the snowpack is wet up to high altitudes where it borders the ground. Possibility of gliding movements over smooth ground. At high altitudes, a well consolidated old snowpack is blanketed by a few centimeters of loose snow. Isolated fresh small snowdrift are generated. A weak layer can persist near the ground on shady side slopes at highest altitude. In south aspects, the snowpack has become patchy even at high altitude.

Increasing number of small loose slides expected on the sunny side due to better weather on Friday.

Wet loose-snow and glide-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.

Little change expected. Strong solar radiation and slight rise in daytime temperatures will increase the wet-snow problem at high and high-alpine altitudes.

Wer snow problem. Danger spots in some places within the old snow in high altitudes
The avalanche danger is low. Spontaneous moist loose-snow avalanches can trigger during the course of the day. 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
Despite the cooler temperatures the settling of the snow surface is insufficient. 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. Partially the snow surface is hard due to strong winds.
Tendency
Thursday night will be clear due to a intermediate high pressure system. During the day dry, mild and sunny weather is called. In the afternoon clouds are coming. Increasing avalanche danger due to wet snow problem.
