Attention: fresh snow and snowdrifts prone to triggering
One sole skier can trigger small-to-medium sized avalanches in the fresh snow and fresh drifts, releases mostly small-sized. Danger zones are often blanketed, difficult to recognize, they occur in steep ridgeline terrain and in wind-loaded gullies and bowls and tend to increase in frequency with ascending altitude. Whumpf noises and glide cracks when you tread upon the snowpack surface are indicators of possible danger. Also naturally triggered avalanches are possible. Small-to-medium glide-snow avalanches are still possible.
Fresh snow plus N/E winds have generated fresh snowdrift accumulations which often lie deposited atop a soft, at intermediate altitudes atop an encrusted old snowpack surface. Bonding deteriorates with increasing altitude. The snowpack is throughly wet up to high altitudes but all-in-all well consolidated. At low altitudes the fresh snow fell on bare ground.
Nighttime skies will be dry and clear. Wednesday will being dry and sunny weather all day long, the skies often cloudless. Winds will slacken off at all altitudes, temperatures rise. At 2000m: -3 to +2 degrees. Light E/SE winds.
Danger of dry-snow avalanches slowly receding. Due to warmth and solar radiation, increasingly frequent slides and loose-snow avalanches expected.
