Still prone to triggering wind slabs in gullies and bowls! Beginning of wet snow problems at lower elevations.
Still prone to triggering wind slabs in gullies and bowls! Beginning of wet snow problems at lower elevations.
The avalanche danger is rated as "moderate" above the tree line. Stormy north-westerly winds create fresh drift snow packs, which in some places can be triggered by individual winter sports enthusiasts as medium slab avalanches. Spontaneous wet snow slides and smaller gliding avalanches can occur at lower elevations.
Stormy north-westerly winds form fresh wind slabs. The connection between the drift snow packs and the old snowpack is not yet sufficient in places. In shady high altitudes, the old snowpack is unfavourably structured in places with crusts and embedded angular crystals. As it warms up, the snowpack at lower altitudes loses stability and can start to glide snow on steep grassy slopes.
From Sunday evening to Monday morning, there will be repeated short rain and snow showers, and a few centimetres of new fallen snow may fall at higher altitudes. The snowfall level will be between 1300 and 1500 metres. The peaks will remain frequently shrouded in clouds and fog, although it will occasionally soften up a little. The wind from westerly directions will remain stormy at higher altitudes! The temperature at 2000 metres will be around -2 degrees, at 1500 metres around +1 degree.
The weather will deteriorate again in the night to Tuesday, with heavier rain and snowfall temporarily setting in after midnight at the latest. Above approx. 1000 m, 10 - 15 cm of new fallen snow is possible by midday on Tuesday. It will remain stormy! The risk of avalanches is increasing!
