Floods swamp homes in Brazil's Amazon region

Across the state of Amazonas, more than 400,000 people have been affected by flooding, said the state's Civil Defense service, many of whom were evacuated as water levels climbed.The Rio Negro river was rising by about 3 centimeters (1 inch) a day and on Monday streets in the center of Manaus were already under water, according to city hall.

Access to the Manaus market on the edge of the Rio Negro is underwater and the city has built raised wooden walkways for pedestrians.

Up the Amazon River, small riverside towns such as Anamã, population 12,700, have been totally flooded, forcing residents to raise the floor levels of their wooden houses or evacuate.

In Manaus, the homes of 4,700 families are in danger. Mayor David Almeida has offered them stipends to rent other dwellings if they are forced to evacuate.
