Moderate avalanche danger at higher altitudes
Older drifts from last week and unfavorably structured intermediate layers inside the snowpack are still prone to triggering in places at high altitudes. Winter sports enthusiasts can trigger small, in isolated cases medium-sized avalanches in wind-loaded zones, particularly on steep W-N-E facing slopes and in transitions from shallow to deep snow, for example at the entry into gullies and bowls.
Bonding of the most recent fresh snow and drifts to the often faceted, expansively metamorphosed old snowpack surface and to unfavorably structured layers inside the snowpack is often only moderate. Due to higher temperatures the snow at low and intermediate altitudes is moist and the snowpack surface melt-freeze encrusted in early morning. At low altitudes there is little snow on the ground.
It is expected to remain dry, predominantly sunny, with only light winds. Temperature at 2000m: dropping slightly from 0 to -2 degrees; at 3000m: -7 degrees. Light, variable winds at high altitudes.
Avalanche danger will recede only gradually.
