Caution: fresh snowdrift!
The avalanche danger above the tree line is moderate. Danger spots are especially fresh driftwood accumulations in the sectors north, east and south. Behind ridgelines as well as in the beginning of gullies and bowls slab avalanches can be triggered by small additional loads. In some places avalanches can slab through low weak layers within the old snow and reach medium sizes.
Fresh wind-drifted snow has formed in the eastern and southern sectors, which is not well bonded to the ground in places. Below this, a succession of crusts and softer layers will form an increasingly unstable snow layering in higher altitudes.
In northern Styria the clouds are piling up beginning of Sunday morning. Snow is possible during the course of the day. It will stay predominantly sunny in the south. Strong northwesterly winds all day is expected. Temperatures at 2000 m will be around -11 to -13 degrees at noon.
The weather will remain cold and windy on Monday. The avalanche danger doesn’t change significantly.
