The death toll from a week of record rains and flooding in central Vietnam has risen to 40, with six people still missing, authorities said Tuesday. The deluge has inundated streets, burst riverbanks, and damaged historic sites in provinces including Hue, Da Nang, Lam Dong, and Quang Tri.

Some areas recorded up to 1.7 metres (5 feet 6 inches) of rainfall in a single day, breaking national records. Nearly 80,000 homes remain flooded, over 10,000 hectares of crops destroyed, and more than 68,000 livestock killed. Remote regions remain isolated by landslides.

The extreme weather continues as Typhoon Kalmaegi, already affecting the Philippines and claiming at least two lives there, is forecast to hit Vietnam early Friday with winds up to 166 km/h (100 mph). Scientists say human-driven climate change is contributing to the increasing frequency and severity of such storms.
