Weather Forecast

In then northern Alps and in the northern Niedere Tauern it will snow on Wednesday. The visibility is bad. Vivid cold northwesterly winds. South of the Alpenhauptkamm, in the Mur-Mürz-Furche due to northern foehn winds, it will get sunny and eventually little snowfall. Alongside the Randgebirge more clouds and foggy weather. Vivid northern winds. Temperatures at 2000 m will be around -7 degrees.

Tendency

Improving weather conditions. On Thursday afternoon it will be predominantly sunny in northern Styria, but in the area of Wechsel it will stay cloudy. Temperatures will be milder. Fresh snowdrift stays prone to triggering.

Avalanche Activity

Fresh snowdrift prone to triggering in the extended expositions east!

The avalanche danger above the treeline is moderate. Due to new snow and vivid northwesterly winds fresh driftsnow is formed in the extended eastern sectors eventually in forest areas. Danger spots especially behind ridgelines as well as in the beginning of gullies and bowls slab avalanches can be triggered by small additional loads. In some places avalanches can slab through low weak layers within the old snow and reach medium size

Snowpack Structure

The snow base is in places unstable due to a succession of crusts and softer layers. On top of it loose snow possible for being drifted and poorly bonded with the old snow. In wind-sheltered areas surface hoar is possible. Additionally new snow will form Wednesday (5 to maximum 15 cm) and due to vivid winds fresh snowdrift accumulations will form, especially in the extended eastern sectors which will be poorly bonded with the existing layers.
