Basel sits where Switzerland, France, and Germany meet along the Rhine river, and receives around 840 mm (about 33 inches) of rain a year, fairly evenly distributed across the seasons with a summer peak from convective storms. As a major Rhine port city, it monitors both routine rainfall and the river’s broader flow, since sustained heavy rain across the wider upstream watershed in Switzerland, France, and Germany can raise river levels significantly over several days. Short, intense summer storms are a separate, faster-moving hazard capable of localized flash flooding. Because these two risks unfold on very different timescales, radar is most useful for the faster local storms. MeteoSwiss operates the national radar network.
