RIO DE JANEIRO, Brazil (CNN) -- A dam burst in the northeastern village of Cocal left a 12-year-old girl dead and three people missing, fire department officials said Thursday, according to Brazil's state news agency.
Steady rain has flooded communities across 10 states in Brazil since early April.
The break occurred late Wednesday afternoon and was blamed on heavy rains in the state of Ceara, the state-run Agencia Brasil reported. Concern over the dam's integrity led officials to order residents to evacuate Cocal for 15 days. But they were allowed to return this week after the dam was deemed safe, it said.
Fire officials said 800 to 2,000 homes located near the dam were inundated, but civil defense officials estimated 500 families -- some 2,500 people -- were affected.
Steady rain has flooded communities across 10 states since early April, killing dozens of people and forcing nearly 800,000 from their homes, according to the Brazilian civil defense agency.
Meteorologists and other weather specialists are divided over the cause of the downpours, particularly in the normally dry northeastern section of the nation. Some say ocean temperatures are to blame, while others say deforestation has led to the climate change.
Brazil has been devastated by rain-swollen rivers for months. Flooding in the southern part of the nation in November and December killed more than 120 people and left about another 30 missing.
