Attention: fresh snow and snowdrifts prone to triggering at high altitudes
The fresh fallen snow and drifts are prone to triggering, one sole skier can trigger small-to-medium sized avalanches. Danger zones occur in steep ridgeline terrain and wind-loaded gullies and bowls, they increase with ascending altitude and are often blanketed, difficult to recognize. 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, the danger is difficult to estimate.
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.
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.
