The recent snowdrifts are still prone to triggering, one sole skier can trigger small-to-medium sized avalanches. Danger zones occur in steep shady ridgeline terrain and wind-loaded gullies and bowls, they increase with ascending altitude. Due to daytime warming and solar radiation, mostly small loose-snow avalanches are possible esp. on sun-basked and rocky steep slopes. The danger of small, in isolated cases medium-sized glide-snow avalances remains difficult to assess.
Recent fresh fallen snow and snowdrift accumulations often lie deposited atop a soft, at intermediate altitudes atop an encrusted old snowpack surface. Bonding deteriorates with increasing altitude, there are often weak layers. On steep shady slopes the uppermost layers of the snowpack are often soft, on sunny slopes already bonded and in the early morning hours capable of bearing loads. The snowpack is throughly wet up to high altitudes but all-in-all well consolidated. Due to daytime rise in temperatures and solar radiation, the snowpack weakens as the day unfolds.
Dry and star-studded nocturnal skies. On Friday, brilliantly sunny, top visibility, mild even on the summmits. At 2000m: 0 to +6 degrees. Light easterly winds.
Danger of dry-snow avalanches not expected to change in high alpine zones. Due to warmth and solar radiation, increasingly frequent slides and loose-snow avalanches expected.
