Monterrey sits in northeastern Mexico, where a semi-arid climate is punctuated by the region’s most serious flood risk: hurricanes and tropical storms moving in from the Gulf of Mexico, particularly from June through November.
Nestled among the Sierra Madre Oriental mountains, the city suffered catastrophic flooding when Hurricane Alex struck in 2010, and remains highly attentive to storms approaching from the Gulf. The devastating floods caused by Hurricane Alex in 2010, which struck the Monterrey metropolitan area, remain the reference event for how quickly mountain-fed rivers here can rise when a tropical system stalls nearby, and radar is essential for tracking these systems in real time.
