Severe storms and record rainfall triggered widespread flooding in Rio Grande do Sul, a state in southern Brazil in late April and early May 2024. As of May 10, at least 113 people have been confirmed deceased, with 146 more reported missing, according to ReliefWeb. More than 337,999 people have been displaced, with nearly 70,000 in shelters. It has been estimated that nearly 100,000 homes have been destroyed throughout Rio Grande do Sul. In Porto Alegre, where more than five months of rain fell in just one week, about 1 million people are without potable water.
Floods have also impacted Uruguay, which is located just south of Rio Grande do Sul, Brazil, and parts of northeastern Argentina. Hundreds of people have been displaced in Argentina along the rising Uruguay River, which forms the border between the two countries. The impact was even greater in Uruguay, where thousands were reported to be displaced.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired a pair of false-color images that illustrate the severe flooding in Rio Grande do Sul. This type of image helps separate water (blue) from vegetation, which appears vibrant green.
The top image was acquired on May 9, 2024, after twelve days of flooding. The large river in the west is the Uruguay River, and the large, flooded lake in the south is Ricon del Bonete Lake in Uruguay. Porto Alegre, Brazil, is located where the swollen Jacui River makes a hard southward turn to flow into the Guaiba River then into the brightly colored Lagos dos Patos.
Clicking on the date under the image reveals a second image acquired on April 28, the day after rain began pummeling the region and before any flooding had occurred. Although skies are clear in this image, heavy cloud cover obscured the region just to the north as the storm system continued dumping torrential rain.
