The Salto Grande Dam (upper right) on the Uruguay River and its surroundings are featured in this image. The dam is located between the cities of Concordia, in Argentina, and Salto, in Uruguay. During Christmas days, the area was affected by heavy flooding, forcing thousands people to evacuate their homes in Paraguay, Argentina and Uruguay. The dark areas in the left part of the image, acquired on January 7, still shows inundated areas near the dam. According to local authorities, flooding was predicted due to El Niño. The current 2015–16 El Niño is one of the three strongest ever recorded, the other two occurred in 1982–83 and 1997–98. El Niño is an irregular oscillation in tropical Pacific currents, with wide-ranging consequences. These might include vastly increased rainfall in South America, drought in Australia and fires across southeast Asia, dying coral reefs in India, severe winter storms in California, a heat wave in Canada and intense hurricanes raging along the Pacific Ocean.
