Severe flooding in southern Brazil has forced 13,000 people from their homes, according to Weathernetwork.com. The flooding has occurred in the World Cup host state of Parana, with the first game there scheduled for Monday.
At least 10 people have been killed as torrential rainfall has not stopped for a week, the site said.
State officials have declared an emergency in 130 cities, which includes World Cup host Curitiba and tourist attraction Iguazu Falls.
Weathernetwork.com said that water flow at the popular falls has grown to 12 million gallons per second, which is the highest in its history.
Access to the waterfall from the Argentinean border has been restricted this week with water having surged onto walkways.
