Sixty-five people are now confirmed dead in Brazil after heavy flooding and landslides devastated southern Santa Catarina state.
Civil defense officials Tuesday said the disaster has affected an estimated 1.5 million people, leaving 150,000 without electricity.
The officials said eight towns remain completely cut off from power and clean water supplies.
At least 52,000 people were forced to flee their homes after days of heavy rains spawned mudslides that buried buildings and destroyed roads.
Officials said there is still a risk of more landslides.
Flooding also cut natural gas supplies after rupturing a pipeline that runs from Bolivia to Brazil.
The town of Ilhota was the hardest hit by the floods, with 15 people killed after waters rose more than nine meters above normal.
Another 13 people died when they were buried by mudslides in the city of Blumenau - a tourist attraction founded by German immigrants and known for its annual Oktoberfest celebration.
Some information for this report was provided by AFP, AP and Reuters.
