Brazil President Dilma Rousseff on Tuesday flew over the flood-hit southeastern state of Espirito Santo, where at least eight people have died in days of torrential rain.
Rousseff said two helicopters and army trucks would be sent to the area, where some 46,000 people have been forced to leave their homes, to deliver food and medicine to those affected.
Some 13 centimeters (five inches) of rain fell Sunday night alone in state capital Vitoria and civil defense forces Tuesday warned of further flooding as rivers burst their banks.
State governor Renato Casagrande on Saturday declared a state of alert in the region which borders Rio de Janeiro.
The rain and landslips have left many roads closed and several bridges have collapsed, with authorities saying two thirds of local districts have been affected.
The heavy rain has furthermore left 15 dead since October in the nearby state of Minas Gerais, where Monday a man was found drowned in his car.
Earlier this month, a violent storm left 16 dead in the northeastern state of Bahia.
