Isolated glide-snow avalcnhes, small persistent weak layer

Avalanche danger above 2500 m is LOW. Weak layers inside the old snowpack can on shady slopes above approximately 2500 m still can be easily triggered in very isolated cases, particularly on wind-protected slopes at the foot of rock walls or behind abrupt discontinuties in the terrain. Avalanches can attain medium size. From smooth slopes which have not yet discharged (grass-covered, rock plates) small glide-snow avalanches can release in isolated cases. Due to the shallow snowpack the danger of taking a fall on rocks and stones outweighs that of being buried in snow masses.

On north-facing slopes above 2500 m the snowpack layering is unfavourable due to a sequence of melt-freeze crusts and faceted crystals in the fundament, or else depth hoar. This applies particularly to wind-protected slopes. Overall the snowpack has settled well and is quite compact. Melt-freeze crusts dominate. Snow depths are highly varied. Below 1800 m there is little snow on the ground.

On Monday, sunshine above the fogbanks, only thin cirrus clouds above summit level, visibility will be good. Southerly winds will be strong in the foehn-lanes. At 2000 m: 4-8 degrees; at 3000 m, 1 degrees On Tuesday the peaks will often be shrouded in fog. In the afternoon the clouds will disperse somewhat, visibility improve. Light to moderate westerly winds will be blowing. At 2000M -1 degree; at 3000 m, -7 degrees.

Little change expected. We are waiting for snowfall.
