At a Glance
The Hozgarganta River in Andalusia, Spain, is currently experiencing severe flooding, with a Red Alert status and a Level 1 Municipal Emergency Plan active in Jimena de la Frontera.
Status & Severity
Water levels have reached a dangerous 4.24 meters, surpassing historical safety maximums in several stretches. With Storm Joseph merging with a second Atlantic front, crest predictions remain high as the river basin struggles to process over 180mm of rainfall recorded in recent hours.

Regional Context
The Hozgarganta is the primary tributary of the Guadiaro River and sits within the Los Alcornocales Natural Park. This region is characterized by “canutos”—deep, humid sandstone gorges that funnel rainwater rapidly from the high Sierra del Aljibe. Unlike most Spanish rivers, the Hozgarganta has no reservoirs to control its flow, making it prone to sudden, violent “flash” rises during intense Atlantic storms.
