Avalanches can be treiggered even by one sole skier and grow to large size. Remote triggerings are possible, esp. on shady wind-protected slopes where there has been heavy snowfall. Particularly treacherous are the foot of rock walls. Whumpf noises can indicate imminent danger. Due to solar radiation, increasingly frequent small loose-snow avalanches can be expected. In addition, isolated mostly small glide-snow avalanches are possible in the major areas of precipitation.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Since Tuesday above 1800m, there has been 40-60cm of fresh snow, locally more. The strong-velocity winds have transported the fresh snow, wind-protected zones above 2400m: in the lower part of the snowpack are faceted expansively metamorphosed weak layer. Shady slopes where the snow is shallos above 1800m: fresh snow and drifts blanket a weak old snowpack. Shady slopes below 1800m: the fresh snow lies deposited atop a thoroughly wet old snowpack.
Tendency
Gradual decrease of avalanche danger

Caution: weak layers in old snowpack
Avalanches can be triggered by one sole skier in some pladces and, in isolated cases, grow to large size, particularly on shady wind-protected slopes in zones where snowfall has been heavy. In isolated cases avalanches can fracture down to the wet old snow and sweep it along, releases thereby possibly reaching medium size. In addition, in places avalanches can be triggered in the surface layers, releases usually small but easily triggerable. Due to solar radiation, small-sized loose avalanches are possible.
Snowpack

Since Tuesday above 1800m, there has been 30-40cm of fresh snow, locally more. The strong-velocity winds have transported the fresh snow, wind-protected zones above 2400m: in the lower part of the snowpack are faceted expansively metamorphosed weak layer.

Tendency
No significant change in avalanche danger levels anticipated
Danger level
Isolated danger zones occur on NW/N/NE facing slopes above 1800m
Due to fresh snow and SW winds, small snowdrift accumulations have been generated in gullies and bowls. Isolated danger zones occuron NW/N/NE facing slopes above 1800m.
Snowpack
Fresh snow and snowdrifts lie atop a thoroughly wet old snowpack. Below 1600m, hardly any snow on the ground.
Tendency
No significant change in avalanche danger levels anticipated
Danger level
Very little snow on the ground
Avalanches hardly possible
Snowpack
Rainfall led to the snowpack becoming massively wet in all aspected over widespread areas. There is little snow on the ground.
Tendency
No significant change in avalanche danger levels expected
