Luxembourg City, the capital of the small landlocked Grand Duchy, receives around 850 mm (about 33 inches) of rain a year, fairly evenly spread across the seasons under the same rotating Atlantic weather systems that affect much of western Europe. The city’s dramatic terrain, built across deep river gorges carved by the Alzette and Pétrusse rivers, means heavy rain can produce fast-running water in the lower valley districts even when the plateau above stays relatively dry. Summer convective storms add a further, more localized hazard. Because the city’s steep valley topography creates such distinct local rainfall effects, radar is a genuinely practical tool here. Luxembourg’s national meteorological service, MeteoLux, operates the country’s weather radar.
