Low avalanche danger, only little snow. Observe risk of falling.
Low Avalanche danger. A few danger spots due snow drift deposits in high altitude gullies and bowls and steep areas. There small slab avalanches within the old snow can be triggered by high additional loads. Some areas with thin snowdrift deposits can form. Danger of being swept away and buried as well as risk of falling is to be considered.
In the southern and eastern Styrian mountains only in shady high altitude slopes a snow cover is existing. Only in some areas thin snowdrift deposits can form which are prone to triggering. Snow cover exists only in shady high altitudes. Exposed areas are blown-off and bare or icy. In gullies and bowlsthe old snow cover ist weakend due to faceted snow crystals underneath.
