Avalanches can in isolated cases be triggered from persistent weak layers on very steep shady slopes. These releases are mostly small-sized. The risks of falling and sustaining injuries outweigh those of being buried in snow masses. From place to place, freshly generated snowdrifts are trigger sensitive and require attentiveness. Isolated, generally small-sized glide-snow avalanches are still possible on steep, smooth slopes which have not yet discharged.
The shallow snowpack is generally well consolidated, low in tensions. On shady slopes in high alpine regions, isolated weak layers are still evident inside the snowpck. Due to intermittently strong-velocity foehn winds, the loosely-packed old snow was transported from place to place and small drifts were freshly generated. Little information from outlying terrain is currently available to the Avalanche Warning Service.
Unhindered sunshine will reign all day long in the mountains amid relatively mild temperatures, with winds slackening off. Temperature at 2000m: -3 degrees, at 3000m -3 degrees. Light to moderate westerly to southwesterly winds at high altitudes.
