Cloudbursts drench southern Brazil for four days in late August and produce some of the worst flooding in 30 years. At least 15 people lose their lives in the inundations across southern San Paulo and Parana states, and more than 10,000 people are forced from their homes by rising waters. At least 20,000 people are left homeless, and 8,000 people are rescued by emergency services, in southern Brazil in early October. The Uruguay River crests 13 meters (40 feet) above normal. Torrential rainfall begins about October 9 and is blamed on El Niño. Record heat waves drive thousands of people to the beach during August—the middle of the Southern Hemisphere winter. Temperatures as high as 108 degrees Fahrenheit (42.7 degrees Celsius) are recorded, breaking all records.
