Rain continued to fall on Sunday morning in the coastal provinces of Quang Ngai and Binh Dinh - where at least 20 people were killed," Trung said, adding damage is initially estimated at around $65 million.
The National Flood and Storm Control Agency said in a statement on Sunday that the loss of life ocurred in five central provinces, where the 11 people were also missing. The death toll was cumulative since the floods began on Friday.
It said the floods had affected 98,000 houses in central Vietnam. But disaster officials said that the flood waters have started to recede in some areas, allowing residents to return and begin digging out their homes.
The worst-hit province was Binh Dinh, where the floods killed 12 people, officials said.
In Quang Ngai province, where nine were killed and four people are missing, flood waters rose above a previous peak measured in 1999, submerging many houses, the official Thanh Nien newspaper reported on Sunday.
Flood waters rose quickly after 15 hydropower plants in the central region opened their sluice gates to release water in reservoir protection, the newspaper reported.
