There is little left of people's homes in parts of Santa Catarina
Thirty-three people are now reported to have died, with many thousands forced from their homes, following floods in Brazil's southern Santa Catarina state.
Heavy rainfall over the last two months has led to landslides which have destroyed homes and blocked roads.
Emergency workers have been using helicopters and boats to try and reach those those left stranded.
A state of emergency has been declared and President Luiz Inacio Lula da Silva has offered federal help.
By Monday, more than 20,000 people had been forced out of their homes. Some have been able to stay with relatives and friends, while others have gone to public shelters.
In total more than a million people are said to have been affected by the flooding.
High risk building
Newspaper photographs showed streets submerged by waist-high water levels, and four towns were reported to have been cut off by the floods.
Joao Paulo Kleinubing, the mayor of Blumenau, where at least 10 people have died, said the major challenge would be supplying shelters with medicines and food.
Many of the deaths had been caused by the landslides, the BBC's Gary Duffy in Sao Paulo says.
Heavy rain and flooding in Brazil have been known to lead to high death tolls in the past partly because homes are often constructed in dangerous locations that are vulnerable to landslides, he adds.
State governments have been criticised for not doing enough to stop people building in areas of high risk.
