Andorra la Vella, the highest capital city in Europe, sits deep in the Pyrenees and receives around 900 mm (about 35 inches) of precipitation a year, much of it falling as snow in winter given the mountain elevation, with summer bringing intense convective thunderstorms typical of high Alpine and Pyrenean terrain. The steep valley setting means heavy rain can produce fast-moving flash floods and debris flows on the slopes surrounding the city, a well-recognized hazard during the wettest summer weeks. Because the mountains create such sharp, fast-changing local weather, radar tracking is especially valuable here compared with flatter regions. Andorra’s meteorological service operates weather monitoring for the principality, supplemented by neighboring Spanish and French radar coverage.
