Parts of Serbia and Bosnia are experiencing worst rains and floods since measurements began. Heavy rain and floods were also reported in eastern Croatia.
Serbian Prime Minister Aleksandar Vucic said this is the greatest flooding disaster ever..."not only in the past 100 years; this has never happened in Serbia's history. More rain fell in one day than in four months."
Evacuations of most critical areas are underway. Around 100 000 hoseholds, mostly in central Serbia, are without power.
The worst hit regions in Bosnia are around capital Sarajevo and Zenica.
The center of cyclone was swirling over Serbia for a couple of days.
It is 00:20 in Serbia now (22:22 UTC). More information will be available in the morning.
