After the drought of 2005, drought struck the Amazon region again in 2010. Drier-than-normal conditions were observed in northwestern, central, and eastern Amazonia during austral summer and the rest of Amazonia until the end of the year. Below-normal rainfall and warm temperatures affected the water level of the Rio Negro River, which reached its lowest level since record keeping began 107 years ago. The drier conditions also favored the forest fires in southern Amazonia; the number of fires reported by September was about 200% higher compared to 2009.
