Points saillants

Be aware of the risk of falling on partly icy ridgelines and on shady slopes.

Avalanche Activity

Be aware of the risk of falling on partly icy ridgelines and on shady slopes.

The avalanche risk is low. In below-average snow conditions, there are only individual avalanche prone locations in extremely steep, on shady slopes above the tree line. Small slab avalanches can be triggered here, especially under high additional load. The risk of falling in steep gullies and in steep, partly icy areas adjacent to the ridgeline, crest or summit is higher than the risk of burial.

Snowpack Structure

The snowpack is well below average for the time of year. In sunny slopes, it is mostly bare beyond the tree line. On shady slopes, the thin snow surface is crusted can form and hard, sometimes icy. At higher altitudes it is mostly blown off, only in areas sheltered from the wind is there a little more snow. In extremely steep gullies on shady slopes, angular shapes can weaken the snow base, fundament. Above this, however, there is usually only a little snow.

Weather Forecast

Fog or high fog patches will continue to spread during the night. It will probably only remain clear in the mountains. Friday will generally be very friendly and sunny, even if there are a few high clouds during the day, visibility will be good. In the lowlands there will be some thick fog with an upper limit around 1000 metres above sea level. The temperature at an altitude of 1900 metres will be around -3 degrees. The temperature at an altitude of 1500 metres is between -4 and 0 degrees. In the Ybbstal Alps there will be moderate winds from the south-west, from the Schneeberg to the Hochwechsel the wind will be brisk to strong with gusts of up to 60 km/h from the south-west. No new fallen snow is expected.

Tendency

The avalanche danger remains the same. Clouds and sunshine will alternate on Saturday, and a few snowflakes could fall from the sky in the Semmering and Rax areas. On Sunday, the clouds will quickly clear, the peaks will be covered in fog and at least a few centimetres of new fallen snow will fall in the evening and during the night into Monday. The detailed forecast is still uncertain.
