Under the impact of typhoon Kajiki, from Monday night to Tuesday morning, Hanoi has suffered from prolonged heavy rain, causing many roads to be severely flooded.

7h45 a.m

Typhoon Kajiki has weakened into a tropical depression, continuing to cause heavy rain in northern Vietnam and the north-central region.

The typhoon raged in central Vietnam, focusing on Thanh Hoa, Nghe An, and Ha Tinh provinces, for more than 10 hours. The strongest wind speed was level 12 when it reached the shore, but it decreased to level 8 when it was at the Vietnam-Laos border.

The National Center for Hydro-Meteorological Forecasting said that at 4 a.m., the tropical depression was strong at 61 km/h, level 7, gusting to level 9 in Central Laos. In the coming hours, the tropical depression will move west-northwest at a speed of 15-20 km/h and continue to weaken.

9:20 p.m. Monday

Seven hours of landing in the central provinces of Nghe An and Ha Tinh with wind force of level 10-12, typhoon Kajiki killed one person and made over 600 houses lose their roofs. Thousands of trees fell on power lines, causing widespread power outages.

It is forecasted that in the next three hours, the typhoon will move west-northwest, deep into the mainland of the southern Nghe An-northern Ha Tinh area at a speed of about 15 km/h.

5:30 p.m.

Typhoon Kajiki's center is hitting Nghe An and Ha Tinh provinces with wind force of level 12, tearing off corrugated iron roofs and doors of houses in the coastal areas.

Quang Tri and Thanh Hoa provinces have strong winds and heavy rain, causing some damages.

3:30 p.m.

Nguyen Van Huong, head of the weather forecast department under the National Center for Hydro-Meteorological Forecasting, told local media that the typhoon's center has not yet completely made landfall, and is still two thirds of it at sea. "In the next 1-2 hours, the typhoon's center will be completely inland."

It is heavily raining in Hanoi under the impact of the typhoon.

3 p.m.

At 3 p.m., the eye of typhoon Kajiki hit the coast of Nghe An and Ha Tinh provinces, with winds of 133 km/h, level 12, knocking down many trees and tearing off the roofs and doors of coastal restaurants.

2 p.m.

At 2 p.m., the center of typhoon Kajiki is in the coastal area of Nghe An-Ha Tinh, causing strong winds of level 12, knocking down a series of trees and tearing off the roofs of level 4 houses.

A level 4 house is a low-cost, one-floor house which has a simple load-bearing structure and is commonly seen in rural areas.

Typhoon Kajiki, the fifth typhoon set to strike Vietnam so far this year, was located around 140 km east-southeast of Nghe An province and 120 km east of Ha Tinh province at 9 a.m. on Monday, with sustained winds of 134-166 km/h (level 13-14) and gusts reaching level 16.

According to the National Center for Hydrometeorological Forecasting, the typhoon is expected to make landfall later Monday and has already forced the evacuation of thousands of people in high-risk areas from Ninh Binh province to Hue city.

Local authorities in the north-central province of Thanh Hoa alone have relocated 1,800 households from Nghi Son, Quang Xuong and Sam Son, with further evacuations underway in Hoang Hoa.

Ha Tinh province has moved more than 14,000 residents, mainly in low-lying coastal communes like Thien Cam and Ky Anh.

Deputy Prime Minister Tran Hong Ha, chairing an emergency meeting from the Government’s forward command office at Military Region 4 (based in Nghe An province), warned central provinces from Quang Tri to Thanh Hoa to complete evacuations before 11 a.m. on Monday and ordered residents not to leave their homes between 11 a.m. and 6 p.m.

He said that the storm could be as strong as super typhoon Yagi, which devastated northern provinces in 2024. Level-four houses (those with tile, tin or asbestos roofs) could collapse, and even high-rise buildings may suffer serious damage. Ha urged localities to reinforce homes and strengthen communication with residents.

Highlighting the critical role of communications in command and coordination, Ha instructed Viettel and VNPT to immediately check equipment for local leaders and disaster response officials.

He assigned the Ministry of Agriculture and Environment and the Ministry of Industry and Trade to take overall responsibility for regulating reservoirs and dams. Local authorities were asked to conduct early inspections, make prompt proposals, and strictly prevent incidents caused by negligence.

Flood risks

Heavy rain is forecast to follow Kajiki’s landfall, with accumulations of up to 600 mm in some areas. Authorities have raised concerns about severe flooding in low-lying urban centres, along with flash floods and landslides in mountainous districts.

In Ha Tinh province, six reservoirs, including Song Rac and Boc Nguyen, have begun emergency water discharges to ease pressure on dams. Meanwhile, Thanh Hoa has established a forward command post in Quan Hoa district to coordinate disaster response in the province's mountainous western area, where landslides and road blockages are expected.

The Ministry of Agriculture and Environment reported 43 weak points in coastal dikes from Ninh Binh to Hue. Most sea dikes are designed to withstand storms of only level 9-10, raising fears they could be overtopped by Kajiki’s winds and storm surges.

Particularly vulnerable sections include Hai Binh in Thanh Hoa, which was breached in 2017, and dikes at Hoi Thong, Loc Ha, and Cam Nhuong in Ha Tinh.

By Monday morning, winds of level 5-6 and heavy rain had already been reported in southern and western Thanh Hoa, while stronger gusts swept the Ha Tinh coast.

In Ky Anh, residents rushed to secure their homes with sandbags, ropes and makeshift reinforcements, while shops closed and streets emptied. Construction crews dismantled scaffolding and secured equipment ahead of the storm.

Meteorologists explained that Kajiki has maintained its intensity close to shore due to warm sea surface temperatures of up to 30 degrees Celsius, favourable atmospheric conditions and additional energy from the southwest monsoon.

Vietnam’s meteorological agency said that international forecasters hold a similar view of the storm’s expected intensity at landfall, estimating it at level 13-14 in Japan and mainland China, and level 14 in Hong Kong.

Authorities have suspended the opening of schools in Thanh Hoa today and tomorrow, while work crews and hundreds of heavy machines have been mobilized to secure dikes, reinforce transport links and stand ready for search and rescue.

The typhoon is forecast to strike between midday and late afternoon on Monday, with winds of level 12-14 and gusting to level 16, in southern Thanh Hoa, Nghe An and northern Ha Tinh provinces. Surrounding provinces may experience winds of level 8-11, with dangerous gusts extending far inland.
