Heavy rain caused flooding and landslips Wednesday (August 27, 2025) in parts of Southeast Asia, where at least eight deaths were reported in the aftermath of a tropical storm.

Flooding occurred in several northern and central provinces of Vietnam, seven people died, one was missing and 34 were injured, state media reported.

Nearly 20 cm of rain fell overnight in parts of northeast Vietnam and flood warnings remained for some riverside areas.

In Thailand, one person died and another was missing from a landslip Wednesday (August 27, 2025) in part of the northern city of Chiang Mai.

Thailand’s Department of Disaster Prevention and Mitigation said many homes were affected and a few people were injured from flash flooding and landslips in northern provinces.

Thailand’s Meteorological Department warned of heavy rain in northern and northeastern regions Wednesday (August 27, 2025). Residents in foothills and low-lying areas near waterways were warned about possible flash floods and landslips.

The rain was part of the aftermath of Tropical Storm Kajiki, which made landfall Monday (August 25, 2025) afternoon in central Vietnam, where thousands of people were evacuated from high-risk areas.

Kajiki earlier brought winds and rain to China’s southern Hainan Island.

Scientists published a 2024 study warning seas warmed by climate change will result in Southeast Asia’s cyclones forming closer to land, strengthening faster and lasting longer, raising risks for cities.

Typhoon Kajiki killed at least three people and injured 10 others in Vietnam, authorities said on Tuesday (August 26, 2025) as they warned that heavy rains could cause flooding and landslips.

The storm damaged nearly 7,000 homes, inundated 28,800 hectares of rice plantings and felled 18,000 trees, the government said in a statement. It also brought down 331 electricity poles, causing widespread blackouts in Thanh Hoa, Nghe An, Ha Tinh, Thai Nguyen and Phu Tho provinces.

Streets in the capital Hanoi were severely flooded as heavy rains fell on Tuesday (August 26, 2025) morning, paralysing traffic. Cars were seen submerged up to their roofs in water.

Flood water also surrounded residential areas in the city, which is preparing to host the country’s largest National Day parade in decades next week as it celebrates the 80th anniversary of its founding.

Video clips on state media showed that water at the West Lake, the largest lake in Hanoi, has overflowed its bank, as rain continued to fall.

Several villages in Bac Ninh province have also been isolated due to flooding, state media reports said.

After making landfall on Vietnam’s north central coast on Monday (August 25, 2025) afternoon, Kajiki has since weakened into a tropical depression as it moved across to Laos on Tuesday (August 26, 2025) morning, the national weather agency said.

The agency warned that rain will continue in several parts of northern Vietnam, with some areas likely to get up to 150mm in six hours, potentially causing flash floods and landslides.

Before making landfall in Vietnam, Kajiki skirted the southern coast of China’s Hainan Island on Sunday (August 24, 2025), forcing Sanya City on the island to close businesses and public transport.

In Thailand, the Meteorological Department warned of heavy rain nationwide Tuesday (August 26, 2025). Residents in foothills and low-lying areas near waterways were warned about possible flash floods and landslips.

Strong winds and heavy rain whipped southern China’s Hainan island and nearby parts of Guangdong province on Sunday (August 24, 2025), as Typhoon Kajiki passed over open waters to the south and headed toward Vietnam’s central coast.

About 20,000 people were evacuated from potentially hazardous areas ahead of the storm, China’s official Xinhua News Agency said.

Fishing boats returned to port, and more than 21,000 crew members came onshore.

A short video posted online by Guangdong Radio and Television showed winds snapping off tree branches and heavily rocking a docked boat and sending waves sliding over the pier.

Kajiki gained strength as it moved west over the sea with maximum sustained winds of 162 kilometres per hour, China’s National Meteorological Centre said.

Rainfall of 25 to 35 centimetres was forecast for the southern parts of Hainan Island, including Sanya, a popular beach resort.

Sanya shut down businesses and scenic tourist areas and halted public transportation and shipping, Xinhua said. A social media post by the city urged residents not to go out unless necessary.

Kajiki, which can mean spearfish or swordfish in Japanese, was expected to make landfall on Vietnam’s coast on Monday afternoon.

Farmers in the city of Hue were rushing to harvest their rice crops before the arrival of the storm, the official Vietnam News Agency said.

Coastal provinces have banned ships from going out to sea starting Monday and were calling in those already out, the news agency said. Authorities have asked provinces and cities to reinforce dykes, reservoirs and irrigation systems.
