El Niño may trigger up to 15 ravines in Lima; Chosica, Chaclacayo, Cieneguilla at risk

Peru's Cenepred warns that intense rains linked to El Niño could activate up to 15 ravines in the Rímac, Chillón, and Lurín river basins, threatening districts including Chosica, Chaclacayo, and Cieneguilla. The forecast is based on seasonal climate models, but the exact timing and intensity of rainfall remain uncertain. This poses a significant landslide and flash-flood risk to vulnerable hillside communities in Lima's outskirts.
