Overview
- The park restricted the Circuito Superior and other river‑adjacent routes to protect visitors and staff after authorities recorded extreme rises in the Río Iguazú.
- The river’s flow reached reports of about 17,700 cubic metres per second in the early hours of Monday, Oct. 26, a spike that triggered the most recent round of preventive closures.
- Provincial agencies and the Policía de Misiones reported evacuations and property damage across Misiones, with more than 150 people moved from flood‑threatened homes and scores of houses affected.
- At least 14 fluvial international crossings were suspended and multiple bridges and local roads faced restrictions, disrupting transport and border services in the region.
- Hydrological and meteorological services link the event to an active El Niño, warn the crest will keep moving downstream, and say authorities will use hourly gauge data to phase reopenings and relief operations.
