Uruguay – Flooding Uruguay River Displaces 1,700

Increasing levels of the Uruguay River and its tributaries have forced around thousands to evacuate their homes in Uruguay, Argentina and Brazil.

Uruguay

Uruguay’s National Emergency System (SINAE) reports that flooding of the Uruguay River has displaced 1,754 in the departments of Salto, Paysandú and Artigas. Some of the evacuees have been in temporary accommodation for over 1 week.

Some areas have been affected by flooding since 24 May after a storm brought heavy rain to river catchments. On May 26 evacuations were carried out in Artigas, Cerro Largo and Salto and in Paysandú two days later. By 30 May around 500 people had evacuated their homes. The number of those displaced has risen over the last 3 days after further rainfall in the Uruguay River basin.

From the total number displaced, 573 were evacuated by the authorities to temporary shelters and 1,098 were self-evacuated and are staying in private homes or self-managed camps. SINAE says that those displaced are receiving comprehensive care, including shelter, food and medical supplies.

The worst hit department is Salto, where almost 1,300 have been displaced. In Paysandú, 408 people have been displaced and 47 in Artigas.

The department of Cerro Largo has also been affected by floods. However, 45 people who were evacuated earlier in Rio Branco in Cerro Largo have since been able to return to their homes.

More heavy rain is expected early next week. With river levels already high and soil saturated, SINAE says that further evacuations are likely.

Brazil and Argentina

Parts of the neighbouring state of Rio Grande do Sul in Brazil have also been affected by flooding. As of 31 May over 2,500 people had been displaced.

On 27 May evacuations were carried out in parts of Argentina as a result of flooding from the Uruguay River. According to the Telam news agency, 32 families were evacuated in Concordia and a further 17 families in Concepción del Uruguay.
