Fresh snowdrifts are still prone to triggering
Fresh snow and freshly generated snowdrift accumulations are prone to triggering at high altitudes. Size and frequency of danager zones increase with ascending altitude. Exposed ridges and crests are often windblown and bare of snow. Esp. intermediate altitudes evidence surface hoar. One person can trigger small-to-medium avalanches in gullies and bowls and behind abrupt discontinuities in the terrain. In extremely steep and rocky terrain, small to medium sized loose-snow avalanches are possible.
The latest batch of fresh snow was able to settle and consolidate at low altitudes. It often blankets trigger-sensitive snowdrift accumulations. Bonding of fresh snow and drifts to the old snowpack and with itself is often poor. Small to medium naturally triggered releases and danger signals confirm how prone to triggering the snowpack is.
Nocturnal hours: final snow showers will come to an end, most of the night will be dry. Sunday: thoroughly sunny. Starting at midday, clouds will move in from the northwest, visibility deteriorate, it will become cold and windy. At 2000 m: -7 degrees. Brisk to strong northerly winds.
The forecast for Monday is still uncertain, probably scattered clouds in the morning and snow showers in the afternoon. Avalanche danger will recede.
