What it means on the border

Both Iguazu parks open in the rain: what closes for safety is a walkway section, and only in a strong river flood. The river reading is at how the Falls are today; strong wind and heavy rain slow the crossing, and the queue is at bridge queue. The forecast for all three sides is at border weather.

This story is generated from the official warning as soon as it is published and updated while the alert is active.
