Circumvent snowdrift accumulations
Avalanche danger above 2000m is MODERATE. Slabs, mostly small-sized, can be triggered even by minimum additiional loading both near to and distant from ridgelines and behind protruberances in the landscape on north, east and south facing slopes. If they fracture down to more deeply embedded layers in the snowpack the releases can grow to medium size. Isolated small-sized glide-snow and loose-snow avalanches can trigger naturally.
On top of a shallow and relatively compact snow cover, less than40cm of snow and drifts (with embedded graupel) lie deposited. In wind-protected terrain the fresh snow is still very loosely-packed, winds have generated a bonded slab. The border to the old snowpack can serve as a weak layer, more deeply embedded weak layers are triggerable only in isolated cases.
A few snowflakes during the evening and early part of the night in Northern Alps and Niedere Tauern. Then, nocturnal skies will be free of precipitation, residual clouds will increasingly disperse. On Monday, mostly brilliant sunshine. At 2000m warming up to about -6 degrees; at 3000m: -9 degrees. Winds will shift to northeasterly and be blowing often at strong velocity, windspeeds reaching 50 km/hr.
Avalanche danger levels gradually decreasing due to higher temperatures, snowdrift accumulations are stabilizing
