Relentless rains and floods have killed at least 41 people in central Vietnam since the weekend, while a search continues for nine still missing, state media reports.
The deluge has submerged more than 52,000 homes and left half a million households and businesses without power, according to reports. Tens of thousands of residents have been evacuated from the flood-affected regions.
Rainfall has exceeded 1.5m (5ft) in several areas over the past three days, even rising beyond the 1993 flood peak of 5.2m in some parts.
