Ettelbrück, in northern Luxembourg at the confluence of the Alzette and Sauer rivers, receives around 850 mm (about 33 inches) of rain a year, similar to the rest of the country. The town’s position at this river confluence means it has a documented history of localized flooding during periods of sustained heavy rain across the surrounding Ardennes foothills, a slower-building risk compared with faster local summer thunderstorms. Because these two hazards operate on different timescales, radar is most useful for tracking the faster-moving storms rather than the rivers’ broader seasonal flow. MeteoLux operates the national weather radar network.
