Fresh snowdrifts accumulating near ridgelines
Avalanche danger above the treeline is moderate. Where fresh snowfall transported, trigger-sensitive snowdrifts accumulating in some places which can be released by one sole skier. Danger zones occur particularly in ridgelines zones and behind protruberances in the landscape. Small-to-medium glide-snow avalanches still possible. Caution urged below glide cracks.
Up to 10-20cm of fresh snow is expected, deposited atop a widespread favorable old snowpack surface. Where winds reach transport velocity, soft layers will be generated inside the fresh snow and fresh drifts which can be weak layers. The entire snowpack can glide over steep rocky plates or grass-covered slopes.
Nocturnal skies will be mostly heavly cloud-covered, foehn winds will ease off significantly by midnight. In the latter part of the night, snowfall will set in from the south and west. Snowfall level: initially above 1500m, descending to valley level by morning. Initially, rainfall is possible in the southern regions up to 2000m. On Tuesday, snowfall from west and south, quickly spreading to all mountain regions. In the afternoon, drier from the west, possibly with brief bright intervals. All in all, in southern regions over 30cm. Visibility mostly heavily reduced. Winds mostly light to moderate, only at summit level in the Northern Alps will winds be brisk. At 2000m. -7 to -3 degrees; at 3000m: -11 degrees.
Avalanche danger levels expected to decrease slightly
