Heavy rains triggered flooding and landslides across parts of Southeast Asia on Wednesday, claiming at least eight lives in the wake of a tropical storm.

In Vietnam, flooding hit several northern and central provinces, leaving seven dead, one missing, and 34 injured, according to state media. Nearly 20 centimeters (8 inches) of rain fell overnight in northeastern regions, prompting ongoing flood warnings for riverside areas.

In neighboring Thailand, heavy rainfall from Tuesday evening into Wednesday caused floods in multiple northern provinces. In Nan province, rising rivers forced evacuations as homes were inundated. Officials reported that over 600 people were affected. One person died, several were injured, and seven—including an eight-year-old—went missing following a landslide in a small village in Chiang Mai province.

Thailand’s Department of Disaster Prevention and Mitigation said flash floods and landslides damaged numerous homes and caused injuries across the northern provinces. The Meteorological Department warned of continued heavy rain in northern and northeastern regions, cautioning residents in low-lying areas and foothills near rivers about potential flooding and landslides.

The downpours followed Tropical Storm Kajiki, which made landfall Monday afternoon in central Vietnam, prompting the evacuation of thousands from high-risk areas. The storm also brought winds and rain to southern China’s Hainan Island.

A 2024 scientific study highlighted that warming seas due to climate change are causing Southeast Asian cyclones to form closer to land, intensify faster, and last longer, increasing risks to urban areas.
