Regular floods
Roads have been closed due to floods and some national train services cancelled.
The central region, incorporating the Central Highlands coffee belt, often suffers from floods and storms between July and October.
Rain since Friday disrupted the coffee harvest and bean drying in central highland provinces, thus delaying the bean flow to sea ports. Vietnam is the world's top robusta coffee bean producer, accounting for around 17 percent of the world's output.
More rain was forecast in the coffee-growing region on Sunday, state forecasters said.
