Osijek, in eastern Croatia’s Slavonia region on the Drava river, receives around 700 mm (about 28 inches) of rain a year, with a fairly even seasonal spread and a modest summer peak from convective storms typical of the flat Pannonian plain. The Drava has occasionally seen elevated levels during sustained heavy rain across its upstream watershed, though this is a slower, more gradual risk compared with the faster local thunderstorms that affect the city and its extensive surrounding farmland more routinely. Hail is a recognized risk for the region’s agriculture during the most intense summer cells. Because these storms can develop quickly, radar tracking is a practical tool for the region’s farming community. Croatia’s DHMZ operates the national radar network.
