Typhoon Kajiki made landfall over eastern Vietnam, battering the coastal areas with strong gusts, according to forecasters who warned that heavy rains and flooding will persist across a much wider area.
Vietnam was preparing for the most powerful storm of 2025 as authorities shut down airports and schools and began mass evacuations.
Earlier, Typhoon Kajiki, with gusts of up to 166kmph (103mph) at sea, was about 110km off the northern part of Vietnam’s central coast and was expected to make landfall on Monday afternoon.
The government had earlier warned: “The situation is extremely dangerous and not safe for any vehicles or structures, such as tourism or fishing vessels and aquaculture raising facilities”, adding that Kajiki would bring heavy rains, flooding, and landslides.
On Monday afternoon, state television showed large waves crashing into breakwaters and streets in coastal towns already inundated by the storm surge.
Vietnam had also evacuated over 586,000 people from central provinces, including Thanh Hoa, Quang Tri, Hue, and Danang, where Typhoon Kajiki was expected to make landfall on Monday, according to state media.
The National Center for Hydro-Meteorological Forecasting (NCHMF) had also warned of widespread heavy rainfall along the east coast.
According to the BBC, the real threat from Typhoon Kajiki comes from heavy, prolonged rainfall. Northern Vietnam could see 300-400mm of rain, causing widespread flooding and landslides that may affect a large area, even after the winds weaken.
The storm was earlier forecast to strike provinces that are less industrialised than the area affected last year by Typhoon Yagi, which killed around 300 people and caused property damage of about $3.3bn.
Vietnam, with its long coastline along the South China Sea, is highly prone to deadly storms that trigger flooding and mudslides.
Kajiki is projected to continue inland across Laos and northern Thailand, extending its impact beyond Vietnam.
By Monday, the government reported more than 16,500 soldiers and 107,000 paramilitary personnel were mobilised for evacuation and search-and-rescue operations.
Authorities also said that over half a million people would be evacuated from vulnerable areas and that boats should remain in port.
Two airports in Thanh Hoa and Quang Binh provinces were closed, and Vietnam Airlines and Vietjet cancelled dozens of flights.
Kajiki had previously skirted the southern coast of China’s Hainan Island, prompting business and transport closures, though conditions were expected to improve by Monday night.
According to Vietnam Plus, deputy prime minister Tran Hong Ha called on local authorities to stay alert and directed police to keep residents indoors from 11am to 6pm on 25 August, while chairing an emergency meeting to coordinate response measures for Typhoon Kajiki.
On Sunday, Typhoon Kajiki passed near the southern coast of China’s Hainan Island as it advanced toward Vietnam, prompting Sanya City to shut businesses and suspend public transportation.
By Monday morning, authorities in China’s southernmost province downgraded typhoon and emergency alerts but cautioned that heavy rainfall and isolated storms could still affect southern Hainan. The provincial meteorological authority predicted that weather conditions would improve by Monday night.
Local reports indicated that many residents in the popular resort city of Sanya sought shelter in underground garages on Sunday evening.
Overnight, several large trees were toppled, leaving streets littered with broken branches by Monday morning.
