Persistent weak layers
- Above 1,800 m
Main danger: weak layers in old snowpack
Main danger: weak layers in old snowpack
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. Whumphf 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.
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.
On Thursday, weak high-pressure impact will bring very sunny weather. Visibility will be very good. A few clouds will move into the western massifs at the end of the day. Only light winds from southerly directions. At 2000m: -1 degree; at 3000m: -5 degrees. Source: GeoSphere Austria
