Wrocław sits on the Oder river in southwestern Poland and receives around 600 mm (about 24 inches) of rain a year, with a summer peak from thunderstorms typical of the region. The city experienced catastrophic flooding in 1997 when extreme, sustained rainfall across the Oder’s upper watershed in the Sudeten mountains and Czech Republic sent floodwaters through the city that took weeks to fully recede, prompting a complete overhaul of the region’s flood defenses in the years since. That event remains a defining reference point for how seriously the city treats river flood risk today. Faster, more localized summer storms are a separate, more routine hazard. Because both risks matter but unfold so differently, radar is most useful for the faster-developing local storms. IMGW operates the national radar network.
