Floods and landslides caused by heavy rain in south-eastern Brazil have killed at least six people and forced thousands from their homes.
A total of 66 towns cities in Minas Gerais state have declared a state of emergency.
In the town of Ouro Preto two taxi drivers died when a bus station was destroyed by a landslide.
Floodwaters are also threatening hillside communities in Rio de Janeiro state that were devastated a year ago.
Flooding is common in southeastern Brazil during the rainy season. Nationwide, more than 2m people have been affected by this year's rains, Brazil's civil defence force says.
About 10,300 people have been evacuated, and 3,000 homes have been destroyed.
Many roads have been blocked, making it difficult to get help and supplies to affected areas.
Last year floods killed more than 800 people, in what officials said was the worst natural disaster ever to befall Brazil.
Most of the deaths were in towns in the mountains north of Rio de Janeiro such as Nova Friburgo, which are again suffering from intense rains.
Since then, the Brazil government has set up an early warning system to monitor weather rainfall and ensure people evacuate before floods strike.
There has also been heavy investment in flood protection.
Minas Gerais state governor Antonio Anastasia said disaster prevention measures had proved effective.
"Given the quantity of rain, we can observe that the system of alerts and evacuation are working well," he said

Heavy rains in Brazil's southeastern state of Minas Gerais have caused severe flooding and left at least seven dead, three missing and some 10,000 homeless.
Authorities put over 50 towns in the state on high alert for mudslides and the Civil Defence authority said that it is trying to evacuate residents living on unstable hillsides.
In the city of Ouro Preto, a landslide wiped out a bus station, killing two taxi drivers who were parked outside the building.
The death toll in the state, which currently stands at seven, is expected to rise as authorities said three people remain missing.
On the streets, some people waded in water up to their necks while others others used boats to help firefighters.
One local resident who abandoned her house described the effects of the floods on her.
"Today I woke up desperate. We are suffering, one can only going through this to understand. It is really tough," she said.
Outside Rio de Janeiro, floods are threatening the same hillside communities that a year ago were hit by floods and mudslides which killed more than 800 people.
