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, snow and drifts lie deposited. Overnight, surface hoar can form. In wind-protected terrain the fresh snow is still very loosely-packed, winds have generated a bonded slab. The border to the old snowpack and loosely-packed snow inside the snowdrifts can serve as a weak layer, more deeply embedded weak layers are triggerable only in isolated cases.
Nighttime skies on Monday night will be partly cloudy, low temperatures at the valley floor, warmer at high altitudes. In early morning hours at 2000m: between -3 and -5 degrees, later in the day up to -2 degrees; at 3000m: -6 degrees. Tuesday will be sunny, with outstanding visibility. In the afternoon, some high-altitude cloudbanks will move in, visibility can become diffuse. Winds will slacken off during the night, be blowing only at light to moderate strength from the northeast, brisker at high altitudes (60 km/hr).
On Wednesday, mostly cloudy skies, minor snowfall. Older drifts are settling only slowly.
