Officials say more than 500 people are known to have died in the floods - the country's worst in decades.
Mountainous areas north of Rio de Janeiro have been hit by the heaviest downpours in 44 years.
The rain caused rivers of mud to rush down the mountains and tear through towns, levelling houses and throwing cars over buildings.
More than 5,000 people have been left homeless, and officials said at least 511 people had died.
