Over 100mm of rainfall was recorded over Bosnia and Serbia during Wednesday and Thursday last week (14th & 15th May 2014), with media reports of much higher rainfall accumulations in places.
The heavy rainfall was caused by a slow moving area of low pressure through the whole depth of the atmosphere
The subsequent flooding was reported to be the worst in 120 years in Bosnia since records began in 1894. A state of emergency has been declared in 18 towns and cities, including Belgrade. The Serbian Prime Minister declared this the greatest flooding disaster ever, with more than four months worth of rain falling on one day. Rivers across the region are now believed to be at record levels.
The system that caused the heavy rainfall has now moved away eastwards with predominately dry weather expected for the rest of this week. Temperatures are expected to be close to normal for the time of year with relatively light winds. However the longer range forecast shows the potential for further heavy rainfall next week.
There have been reports in the media that the flooding has sparked a mass evacuation with fears that flooding and mudslides could expose landmines left by the Bosnian war.
River gauges show many of the rivers have peaked, but despite the dry forecast for the next few days there are concerns (from local hydromet departments) that river levels may rise again on Tuesday evening (20th May) and Wednesday morning (21st May) on the River Sava and River Danube. Further flooding could threaten a major power station on the River Sava.
