Nine people died and 17 others were missing after Typhoon Bualoi hit Vietnam on Monday, with houses damaged and power grids knocked out as the storm brought flooding rains and huge swells before losing some of its strength as it headed towards Laos.
Bualoi had moved along the country's northern central coastline before making landfall early on Monday, causing waves as high as eight metres, according to the national weather agency.
A local official in Thanh Hoa province, Nguyen Ngoc Hung, died when a tree fell on him as he returned home after a night of storm preparations, reports said.
One person was killed after being swept away by floodwaters in Hue city.
Another fatality was reported in Danang.
Six of the deaths occurred in the scenic province of Ninh Binh, where strong winds collapsed houses.
Seventeen fishermen were missing after huge waves hit two fishing boats off Quang Tri province, while another fishing boat lost contact during the storm, according to the agency.
"I've witnessed many storms, and this is one of the strongest," said 45-year-old Nguyen Tuan Vinh in Nghe An province as he was cleaning up debris.
Vinh's neighbours said they stayed up all night trying to protect their homes, even as the power to their apartment building went down.
"I stayed awake the whole night fearing the door would be pulled off by strong winds," said resident Ho Van Quynh.
By 11:00 am (0400 GMT), the typhoon was moving over Nghe An province into Laos, with maximum wind speeds weakening to 74 kph from 117 kph when it made landfall, the weather agency said.
Bualoi has so far damaged 245 houses, inundated nearly 1,400 hectares of rice and other crops, and cut off access to several areas, the disaster management agency said in a report.
No major damage to industrial properties was mentioned in the report, though there are some large factories in or near Bualoi's path, including those owned by Foxconn, Luxshare, Formosa Plastics and Vinfast.
Ahead of the typhoon hitting, the government had evacuated more than 30,000 people, while hundreds of flights were cancelled or delayed as four airports in central provinces were closed.
The development of Bualoi, also known as "storm No10,” shows that this is the fastest moving storm ever in the East Sea.
It took around two days from September 26 to September 28 for the storm to travel more than 1,000 kilometers (621 miles), directly impacting the mainland of the country's northern and central regions.
The cyclone has triggered heavy rains across most of Vietnam since Saturday, and authorities have warned of the risk of severe floods and landslides.
Rainfall in several parts of the country was forecast to hit 500 millimetres from Sunday night through Tuesday, according to the weather agency.
With a long coastline facing the South China Sea, Vietnam is prone to typhoons that are often formed east of the Philippines, where several people died after Bualoi hit there last week.
