Low avalanche danger - only isolated danger spots due to fresh wind drifted snow.
The avalanche danger is low. Dangerous spots occur sporadically in the form of fresh snowdrift deposits. These are located in high entrances to gullies and bowls, especially in eastern exposures. Small slab avalanches can be triggered here in wind drifted snow by even a low additional load. In addition to the danger of burying, the risk of being swept away and falling should also be taken into account.
Older wind drifted snow in the northern and eastern sectors of the high altitudes is largely stable. By Friday, additional small snowdrift deposites will form in the extended eastern sector. At higher altitudes, a succession of crusts and softer layers will form under these snowdirft deposites, creating a somewhat unstable snow layering. At medium and lower altitudes as well as on sunny slopes, the fresh snow lies directly on the previously porous base.
During the night to Friday, a cold front will bring a significant drop in temperatures and stormy north-westerly winds in the Styrian mountains. The snow line will drop down into the valleys, but the snowfall will remain low overall. The snowfall will decrease from the morning hours onwards, while the winds will shift to the north. It will only remain stormy in the east of Styria. From midday, mainly sunny conditions are expected. The wind will remain strong and temperatures at an altitude of 2000 m will be a winterly -10 degrees.
Sunny and cold mountain weather is expected on Saturday. The avalanche danger remains unchanged.
