TL;DR
- Tourist access to Iguazu Falls was temporarily closed by Argentinian authorities.
- The closure was a precautionary measure due to heavy rain and the Iguazu River flowing at six times its normal rate.
- The river's flow exceeded 12,000 cubic metres per second before a gradual decline allowed for reopening.
- The event is linked to a supersized El Niño, predicted to be the largest ever recorded and potentially intensified by global heating.
