A new round of floods and landslides triggered by torrential rain in central Vietnam since the weekend has killed at least eight people, a government report said on Wednesday, with traders also warning that it could hamper the ongoing coffee harvest.

From Saturday night, rainfall has exceeded 1,100 millimetres in several parts of central Vietnam. The region is home to a key coffee production belt as well as the country’s most popular beaches, but it is highly prone to storms and floods.

The fatalities include six bus passengers killed in a landslide on Sunday evening en route from Da Lat to Nha Trang, the government said in the report. Seven people remain missing, including three buried under a landslide in Danang.

“Some coffee farms in low-lying areas of Dak Lak are deep in floodwater,” a coffee trader based in the province said.

Heavy rain is continuing there, slowing down the harvest, another Dak Lak-based trader said.

“Farmers in the province have picked 10%-15% of the beans and they need sunlight to dry them,” the trader added.

Photos published by state media on Wednesday showed homes in several villages in central Vietnam flooded to the roof as stranded residents call for help.

Hundreds of families were evacuated overnight from their flooded homes, Vietnam News Agency reported. In nearby Gia Lai province, schools were also forced to close on Wednesday, affecting 26,000 students.

In the UNESCO-listed ancient town of Hoi An, which was still cleaning up the damage done by a previous round of floods two weeks ago, waters are rising again.

Media photos show tourists and residents moving through the streets of Hoi An on boats, passing inundated cafes and centuries-old wooden houses.

The national weather forecast agency warned of more flooding and landslides on Wednesday, with heavy rain set to continue in the region.
