Low avalanche danger with mostly little snow.
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.
The last rain and snowfall will subside on Thursday evening and the cloud cover will soften, especially in the northern Alps. Low residual clouds will often remain south of the main Alpine ridge. After residual clouds and fog disperse, Friday will temporarily bring quite sunny mountain weather, but clouds will return from the south-west in high and medium-high layers during the afternoon. However, it will remain dry until the evening. The wind will blow moderately to strongly from a south-westerly to north-westerly direction. Temperatures at 2000 metres will be between -2 and +2 degrees, at 1500 metres between -1 and +4 degrees.
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.
