Zaragoza 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.
On the Ebro River, Spain’s largest river by volume, the city closely monitors the Ebro’s level, which has produced serious floods in past decades. 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.
