This is the dramatic moment wind blows away a motorcycle and its sidecar as a typhoon lashes Thailand.

Footage shows the three-wheeler parked in a garage when fierce gusts suddenly struck, pushing the vehicle in Krabi on July 20.

The homeowner was seen running into the house before returning to secure the motorbike, which had come to a stop a few metres away.

Thailand has been among the countries lashed by heavy rain and stormy seas brought by Typhoon Wipha.

In neighbouring Vietnam, a tourist boat was capsized by the storm, leaving dozens of passengers dead. The vessel reportedly overturned after being hit by choppy waves and heavy rain off the coast of Ha Long Bay shortly after 2 pm local time.

The Thai Meteorological Department today predicted more heavy rain and high seas until July 24. It added that around half of Thailand will be battered with increased rainfall due to the typhoon, which made landfall in China's southern Guangdong province on July 20.

Wipha has been downgraded to a tropical storm after hitting mainland China.
