Low avalanche danger, but watch out for fresh wind slab!

The avalanche danger is low. However, fresh snowdrift accumulations in gullies and bowls that have been blown in as well as behind ridges and ridgelines above the tree line are prone to disruption and can be triggered by a single person as a small slab avalanche.

Fresh snowdrift accumulations often lie on faceted crystals or surface hoar, which can act as a weak layer. Apart from this, the old snow surface is only covered by a few centimetres of new fallen snow. In general, kinetic metamorphism weakens the thin snow base, fundament. Windward terrain is usually blown off and almost snow-free.

Light snowfall will begin in the Mürzsteg Alps in the night to Friday, which may intensify briefly in the morning. However, less than 10 cm of new fallen snow is expected in total. The highest peaks will be covered in clouds and visibility will be limited. The wind is blowing strongly from the west to north-west. The temperature at 2000 metres will be significantly milder than recently at around -2 degrees.

The weather will calm down briefly on Saturday morning before moderate snowfall sets in again with an influx of cold polar air. The risk of avalanches increases slightly.
