In Slovenia, one of the worst icestorms in living memory has brought chaos. Icestorms occur when snowflakes melt into raindrops as they descend through relatively warm air but then encounter air temperatures below freezing at ground level. The raindrops are chilled to below freezing, despite remaining liquid.
On contact with ground-based objects, the raindrops freeze instantaneously. The result in Slovenia, after at least two days of freezing rain, has been up to 10cm of solid ice coating all surfaces, breaking electricity pylons, levelling entire forests and snapping car suspension springs.
Almost half the country's forests were said to have been damaged by ice.
