Heed high-altitude snowdrifts

Avalanche danger above 2000 m is moderate. Freshly generated snowdrift accumulations occur mostly near ridges on very steep NW/N/NE facing slopes and in gullies and bowls and can be triggered by 1 person above 2300 m, releases often medium-sized. In steep grass-covered terrain, naturally triggered glide-snow avalanches are possible at any time, usually medium-sized, occasionally larger in starting zones above 2000 m.

Fresh and older snowdrift accumulations lie deposited atop a moistened surface below 2300 m, are well bonded. Above that altitude the drifts on shady slopes lie deposited atop loose surfaces which can be weak layers. On W/N/E facing slopes there are faceted layers near melt-freeze crusts which are trigger-prone in isolated cases. At low and intermediate altitudes the snowpack is already thoroughly wet down to the ground. Hardly any longwave outgoing radiation during the cloudy night. Warmth in the daytime will further weaken the snowpack.

During the night, heavy clouds will pass through but it will remain dry. Southerly foehn winds will be quite stormy in the early part of the night, later on will collapse. On Monday, heavy clouds will again pass through, higher peaks will be shrouded in fog, windows of sunshine most likely in the Northern Alps. Later in the afternoon, esp. in Pinzgau, isolated light showers, snowfall level at 1500 m. Winds will be light from N/NW. At 2000 m: 0 to +3 degrees; at 3000 m: -6 degrees.

Avalanche danger levels are not expected to change significantly.
