A citrus-growing town in the fertile valley south of Monterrey, Montemorelos experiences a climate typical of Nuevo Leon, where tropical storms and hurricane remnants funneled by the Sierra Madre Oriental into river basins governs most rainfall.
The stakes are concrete — flash flooding of rivers funneled by the mountain range is a known issue here, and for Montemorelos specifically, knowing a storm is building matters more than knowing it's merely 'possible'.
