Thousands of houses were blown down by Storm Kai Tak during the night of August 17 as it changed direction and headed for the northern mountainous provinces of Phu Tho and Yen Bai after hitting the coast in Quang Ninh province.

At least three people have died by early Aug 18, while torrential rains damaged hundreds of hectares of crops and floods isolated many villages, according to the Central Committee for Flood and Storm Prevention.

The storm, with winds of up to 73kph, also brought heavy rains to the northeastern region, including Hanoi, Hai Phong and Quang Ninh.

In Hanoi, a taxi driver was killed when a huge tree fell on his cab in Lo Duc Street in Hai Ba Trung district, and at least five others injured as fringe winds hit at about 4pm on Aug. 17.

Initial reports from the State-owned Hanoi Tree and Park Company showed that more than 80 trees, including many more than a century old, were blown down throughout the city.

In less than half an hour, heavy rains created flash floods about 30cm deep in many parts of the capital city and Hai Phong, causing severe traffic jams.

After landing, the storm had weakened into a low tropical depression, and local people have been warned to watch out for flash floods.-VNA
