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
Avalanche Problem
Wet snow
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.
