The death toll from Typhoon Bualoi in south-east Asia has risen to more than 30, as heavy rains continued to lash the region.
In Vietnam, authorities said 19 people had been killed, with 21 still missing, making it the most devastating storm to hit the country this year. Heavy rains on Tuesday raised the risk of more flooding and landslides in northern regions.
Bualoi made landfall on Monday in northern central Vietnam, bringing huge sea swells, strong winds and downpours. Last week, the typhoon killed at least 11 people in the Philippines.
In Thailand, the country’s disaster prevention agency reported flooding in 17 provinces, with Ayutthaya, where four people died, the worst affected, according to the International Federation of Red Cross & Red Crescent.
Rainfall in parts of Vietnam had exceeded 300mm over the past 24 hours, the national weather agency said, with heavy rains expected to continue, including in the capital, Hanoi. “Landslides and flash floods are likely to happen in several areas over the next six hours,” the national weather agency said.
Many streets in Hanoi were flooded on Tuesday and authorities warned that people close to the Red River, which passes through the city, should take precautions.
On Tuesday, Bualoi was heading toward Laos but has been downgraded to a tropical depression, according to the National Center for Hydro-Meteorological Forecasting.
Bualoi’s rains added to last week’s deluge from Typhoon Ragasa and water flowing downstream from the Chao Phraya and Pa Sak rivers. The Thai government erected steel plates and added barriers along the rivers to protect Ayutthaya’s Unesco-listed temples and ruins, including Wat Chaiwatthanaram, one of the country’s most important temples.
Bualoi was a tropical storm when it made landfall in the Philippines last week, although two other tropical storms have since hit the country.
The small island province of Biliran was the worst hit by Bualoi, with 10 people killed by heavy rains and strong winds that triggered flooding and mudflows. Several school buildings, bridges, and hundreds of houses were destroyed. Road clearing operation and water rationing continue as of Tuesday.
Global warming is making storms such as these stronger and wetter, according to experts, since warmer oceans provide tropical storms with more fuel, driving more intense winds, heavier rainfall and shifting precipitation patterns across the region.
