Moderate avalanche danger due to persistent weak layer problem!
Moderate avalanche danger due to persistent weak layer problem!
The avalanche danger is classified as moderate from the tree line upwards. In areas adjacent to the ridgeline, at crossings, behind terrain edges and in steep bowls and gullies, slab avalanches of up to medium size can still be triggered in places, especially in the northern and eastern sectors, even with little additional load. Despite strong southerly winds at times, there are hardly any fresh loads, but if there are, be aware of them.
Older windslab snow and bonded snow lies on an unstable old snowpack that has been transformed by building up. Easily recognisable weak layers are present in the form of faceted crystals without bindings and/or floating snow. Higher up, there may be fresh, small-scale but easily disturbed drifts. In general, there is little snow and the snow cover, snowpack is very unevenly distributed. In addition to completely blown away areas, there are also well-filled areas.
Tuesday will continue on the mountains with plenty of sunshine and very good visibility. In the foehn wind corridors of the northern Alps, a brisk southerly wind with peaks of around 40 km/h will blow. Temperatures at 1500 metres will be around 4 degrees, at 2000 metres around 2 degrees. On Wednesday, a cloudless sky will stretch across the mountains. The sun will shine brightly and visibility will be excellent in the dry air. At first, moderately strong winds from the east to south, but in the afternoon the wind will mostly be light. Temperatures at 1500 m around 2 degrees, at 2000 m around -2 degrees.
Still no significant change in the snow and avalanche situation.
