Sarajevo sits in a narrow valley surrounded by mountains and receives around 950 mm (about 37 inches) of rain a year, with a fairly even seasonal spread and the surrounding peaks helping to intensify rainfall throughout the year. The city experienced severe flooding in May 2014 when extreme, sustained regional rainfall across Bosnia and neighboring countries caused the worst flooding in over a century, with the Miljacka river and surrounding streams overwhelming the valley. Because the mountain-valley setting can trap and intensify storm systems, radar tracking of approaching heavy rain is treated as a genuinely important tool by both residents and regional authorities. Bosnia and Herzegovina’s Hydrometeorological Institute operates the national radar network.
