Caution: fresh and blanketed drifts, glide-snow avalanches

Avalanche danger is moderate at higher altitudes. Main problem: fresh or covered snowdrift accumulations. Danger zones occur in steep wind-loaded terrain and ridgelines and increase in size and frequency with ascending altitude. A medium slab avalanche can be triggered by 1 person. More deeply embedded layers inside the snowpack can usually be triggered only be large additional loading, primarily in transitions from shallow to deeper snow, e.g. at entries into gullies and bowls. At all altitudes in steep terrain and on smooth grass-covered slopes in all aspects, glide-snow avalanches are possible which can reach medium size. Caution in zones below glide cracks.

The fresh fallen snow from the end of last week has been able to settle further and bond with the old snowpack. In places there are soft layers or older snowdrift accumulations which have been blanketed over, and recognizing the danger zones is difficult. Particularly on steep shady slopes above 2200 m, the old snowpack from late autumn still has unfavourable intermediate layers which are triggerable as slab avalanches. There is currently little data available to the Avalanche Warning Service about the snowpack in various regions.

Nocturnal hours: Snowfall and snow showers will slowly come to an end, clouds will disperse. Thursday: Residual clouds will disperse, sunshine will prevail. In afternoon, a few cloudbanks above summit level. Measurably higher temperatures. At 2000 m: -8 to -1 degree. Light to moderate northwesterly winds.

The avalanche situation is not expected to change significantly.
