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.

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.
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.
