Low avalanche danger, but watch out for spontaneous wet snow slides!
The avalanche risk is low. Nevertheless, small, wet loose snow slides and occasional small gliding avalanches are to be expected during the day (wet snow problem). In extremely steep, shady areas above 2000 m, small to medium-sized slab avalanches can still be triggered very occasionally (persistent weak layer problem).
With outgoing longwave radiation, the snow surface can consolidate somewhat, but softens again with sunlight. The thin snowpack becomes damp or wet in all areas and loses firmness or can start to glide on a slippery surface. Only in very shady areas above 2000 metres does the snowpack still have small cold reserves and occasional weak layers in the persistent weak layer. In general, there is very little snow and lower altitudes are increasingly thinning out.
High-pressure boundary. Most of the clouds will clear during the night on Tuesday and it will remain dry. On Tuesday, the sun will shine frequently south of the main Alpine ridge and visibility will often be good with cloudless skies. Only a few cumulus clouds will form during the day. Often brisk winds from the northwest in exposed areas. The temperature at 2000 m will be between +2 and +5 degrees, at 1000 m between +6 and +12 degrees.
On Wednesday, the mountain weather will be sunny again and a touch cooler. The avalanche risk will not change significantly.
