Charleroi, in southern Belgium’s Wallonia region, receives around 830 mm (about 33 inches) of rain a year, slightly more than the northern coastal cities, reflecting its position closer to the higher terrain of the Ardennes. Rain is fairly evenly distributed across the seasons, with summer convective storms occasionally bringing intense short-term downpours to the former industrial city’s hillier terrain. Localized flooding can occur in lower-lying parts of the city during the heaviest storms, given aging drainage infrastructure in some districts. Because summer storms here can develop with limited warning, radar tracking gives useful lead time during the warmer months. Belgium’s Royal Meteorological Institute operates the national radar network.
