An electricity post was pulled down in front of worried residents as a flash flood in northern Thailand.

Footage shows the utility post toppling near the raging deluge in Pua Village, Nan, on Wednesday, July 23, narrowly missing two parked motorcycles.

A local was seen rushing towards the vehicles, apparently attempting to move them before the video ends.

Reports said several roads have been cut off due to heavy flooding, with authorities urging motorists to avoid unnecessary travel.

Residents have also been advised to remain vigilant for flash floods and landslides, particularly those living near canals and mountainous areas.

Typhoon Wipha has been battering Thailand with strong winds and torrential downpours.

The Thai Meteorological Department on Monday predicted more heavy rain and high seas until July 24. It added 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 since been downgraded to a tropical storm after reaching mainland China.
