Low avalanche danger with mostly little snow.
The avalanche risk is low. In a few places, especially in locations above the tree line, snowdrift accumulations can be triggered as small slab avalanches in steep gullies and bowls. Avalanche prone locations and icy areas can be covered with a thin layer of fresh snow. Small, wet slides cannot be ruled out at altitudes below 1500 metres.
There is still significantly less snow than average. A thin, partly bound snowpack covers a very variable and mostly hard old snowpack. In shady gullies and bowls, the connection between the bound snowpack and the old snowpack is sometimes poor. In addition, angular shapes can weaken the snow base, fundament.
It will rain and snow at times, especially in the first half of the night, with a few centimetres of new fallen snow still possible in the Koralm area. Tomorrow, Thursday, will be mostly cloudy, with clouds and fog dominating at first and visibility severely limited until midday. A few snowflakes or raindrops will still fall in places, but there won't be any significant amounts of new snow. The snowfall level will be around 1000 metres. The temperature at an altitude of 1500 metres will be around -1 degree. The temperature at an altitude of 1000 metres is around 1 degree. A brisk wind with gusts around 50 km/h from the south. The wind will weaken in the afternoon.
On Friday, there will be a brief intermittent high with some sunny spells. In the afternoon, it will start to get cloudy again from the west. No change in the avalanche danger is expected.
