Rough seas lashed promenades and coastal areas as Storm Fengshen approached Vietnam.

Footage shows waves crashing onto the damaged paved public walk in Da Nang on October 22.

Waves up to six metres high have battered the Han River embankment, flooding Nhu Nguyet Street and ripping up sections of the sidewalks as the freak weather nears the country's coast.

At 1 am on Thursday, the tropical depression's centre was located around 80 km east-northeast of Da Nang.

The central region, from Ha Tinh to Quang Ngai, is forecast to experience heavy to very heavy rain until Friday, ranging from 100–200 mm, with some areas receiving over 300 mm.

Tropical Storm Fengshen moved westwards through the Philippines, killing at least seven people, leaving two missing and one injured as it swept across the northern and central regions of the country on October 19.

It then emerged into the South China Sea, weakening slightly as it tracked towards southern China and Vietnam. The storm continues to bring heavy rainfall, flooding, and coastal impacts in the coming days, including in parts of Taiwan.
