Fresh snowdrift accumulations will be generated due to snowfall and wind
Fresh snowdrift accumulations will be generated due to snowfall and wind
With ascending altitude the fresh snowdrift accumulations become more prone to triggering in ridgeline zones, gullies and bowls, behind abrupt discontinuities in the terrain. At low altitudes the snow often fell on bare ground. There is still very little snow on the ground. Due to low temperatures, it will be preserved.
As a result of intermittently moderate-strength winds, the loose fresh fallen snow will be transported, particularly in ridgeline and summit zones, generating fresh snowdrift accumulations. These are prone to triggering. At low altitudes the snow frequently fell on bare ground. All in all, there is still little snow on the ground. Due to the low temperatures, it is being preserved.
Nocturnal hours: gray skies, light snowfall, up to 10 cm of fresh snow is possible, amid low temperatures. Sunday: Snow showers will taper off, winds will ease, but visibility will remain reduced. Only the highest peaks of Silvretta and Rätikon will peek out of the cloud cover. Temperature at 2000 m: -12 degrees. Moderate to strong NE winds at high altitude.
Monday morning will have scattered clouds in most regions. As of midday, more clouds will move in from the east. As evening approaches light snowfall will set in. Brisk, cold NE winds will be blowing. Avalanche danger is not expected to change significantly.
