What happened

Weeks of heavy rainfall sent major rivers surging beyond their banks across north-eastern Argentina, inundating neighbourhoods, damaging homes and forcing thousands of residents to seek safer ground. The disaster has particularly affected the provinces of Chaco, Corrientes and Misiones, where communities along the Paraná, Uruguay and Iguazú rivers are coping with rapidly changing water levels.

According to reports published on 23–24 October, at least two people have died and more than 2,000 residents have been evacuated or forced to abandon their homes.

The two deaths in Corrientes

The two fatalities occurred in Corrientes Province, where rural workers drowned while attempting to move cattle between islands threatened by rising floodwaters. The men were reportedly swept away by powerful currents while working to protect livestock. Police and Argentine Naval Prefecture personnel conducted a search operation before their bodies were recovered.

Hardest-hit areas

In Chaco Province, approximately 1,200 to 1,300 people have evacuated or left their homes voluntarily, particularly around Puerto Vilelas and Barranqueras. Neighbouring Corrientes has reported more than 1,000 displaced residents.

In Paso de la Patria, a tourist destination along the Paraná River, floodwaters overwhelmed a protective embankment, allowing water to rush into residential neighbourhoods. Some homes have been submerged almost to their rooftops, while residents who remain face difficult living conditions.

In Misiones Province, storms on 22 and 23 October damaged more than 100 homes and forced road and bridge closures.

Iguazú Falls hit by extraordinary river flow

The flooding has also affected Iguazú Falls, one of South America's most famous natural attractions. During mid-October, the Iguazú River's flow reportedly reached approximately ten times its seasonal average. The enormous volume of water has affected tourism operations, although several visitor circuits have reopened. Access to the famous Devil's Throat section remains closed, according to the latest reports.

Why the flooding happened

The flooding is occurring during an intensifying El Niño climate pattern. Across parts of south-eastern South America, El Niño can increase the likelihood of unusually heavy rainfall and river flooding. Recent heavy rainfall across the upper Paraná, Uruguay and Iguazú watersheds has contributed to the current emergency. Individual flood events are also influenced by local rainfall intensity, soil saturation, river basin conditions and flood defences.

What happens next

Officials are concerned that the flooding may not be a short-lived event. Chaco's provincial Civil Protection deputy secretary, Gustavo Santos, warned that river levels could continue fluctuating for several months. Additional rainfall forecast across the upper Paraná and Uruguay river basins could send another surge of water downstream during the coming week, meaning some communities could face repeated flooding even after initial waters begin to recede.

The immediate concerns are continued river rises, additional evacuations and damage to homes, roads and agricultural land. Residents in affected areas should follow local Civil Defense instructions, avoid flooded roads and never attempt to cross fast-moving water.
