Pamplona sits in Spain’s dry continental interior, where hot summers and cold winters produce a semi-arid climate with modest annual rainfall concentrated in short, sometimes intense spring and autumn storms.
In Navarre near the Pyrenees, the city’s rivers can rise quickly when heavy rain falls over the nearby mountains. Because the region normally receives little rain, its rivers and drainage systems can be quickly overwhelmed when a storm does arrive, making radar tracking of individual storm cells especially useful for anticipating flash flooding.
