These 10-day synthesis images indicate the effects of heavy rains and subsequent floods during May 2014. Between 14 and 18 May, a stationary low-pressure system, generated and further activated through the collision of a polar airflow from the north and warm, humid subtropical air from the southwest, caused persistent rains in south-eastern and central Europe. Daily precipitation amounts on 15 May were as large as 110 mm in several parts of Serbia. The upper panel shows the pre-flood conditions for the Danube and Sava River region in parts of Croatia, Serbia, and Bosnia and Herzegovina, during the first dekad of April, while the lower panel shows the situation for the same region during the 3rd dekad of May, about one week after the most heavy rains.
