New fallen snow and stormy winds lead to an increase in avalanche danger!

New fallen snow and stormy winds lead to an increase in avalanche danger!

The avalanche risk is moderate above the tree line. Fresh snowdrift accumulations can be triggered as small to medium-sized avalanches by individual winter sports enthusiasts in all aspects. The avalanche prone locations are mainly in gullies, bowls and behind terrain edges. Small loose snow slides cannot be ruled out below the tree line.

10 to 20 cm of new fallen snow will be transported by strong to stormy north-westerly winds during the day. Fresh snowdrift accumulations are often deposited on a sufficiently stable old snowpack above the tree line. Weak layers are in the bound layer or transition to the persistent weak layer. Below the tree line, new and wind slab snow is deposited on mostly apery ground.

A striking cold front will move across Styria in the early hours of the night. There will be snow showers and brisk to stormy gusts of wind from the north-west. Thursday will be wintry. It will snow all day, especially in the northern Alps and the Niedere Tauern. To the south, the precipitation may be less heavy, with 5 - 15 cm of new fallen snow. Visibility is very limited. In addition, stormy northerly winds will blow from the main Alpine ridge southwards, becoming gale-force in exposed high altitudes. On the southern side of the Alps, the snowfall will weaken in the afternoon and take breaks. The temperature at 2000 metres will be between -1 and -7 degrees, at 1000 metres between -3 and +2 degrees.

The avalanche risk will increase on Friday. An area of low pressure will bring another 20 to 50 cm of new fallen snow, especially in the eastern mountains. Stormy winds will continue to blow.
