Torrents of raging muddy water crashed into homes and washed away cars and motorcycles as floods from the tailend of Typhoon Yagi caused chaos in Thailand.

Footage shows the deluge collecting branches and other forest debris while surging through streets in Chiang Rai on Wednesday afternoon.

Officials said floods and landslides across the region killed at least six people and left thousands more displaced.

Acting Prime Minister Paetongtarn Shinawatra is to visit the area while the health ministry has sent medical staff, volunteers, and rescue workers to relocate elderly residents to safer areas.

The Thai Meteorological Department warned of more heavy rain until next Tuesday, heightening the risk of additional flash floods.

Kritsayam Kongsatri, director of the Protected Areas Regional Office 16, said the search for missing locals was temporarily stopped amid landslide fears.

Communication was also hindered by poor mobile signal and electrical outages.

He said: 'Officers will resume the search for the missing persons once the situation improves. They will coordinate with all relevant agencies to expedite assistance to the affected families as much as possible.'

Northern Thailand has been battered by continuous heavy rain since September 8 due to Typhoon Yagi's influence.

Yagi, said to be Asia's most powerful storm this year, was downgraded to a tropical storm on Sunday morning, September 8. It killed at least 15 people in the Philippines before slamming into southern China and Vietnam, where it left at least 150 dead and 22 missing.

The Thai Meteorological Department (TMD) had forecasted isolated heavy rains with gusty winds across the northern and northeastern regions as remnants of the cyclone strengthened the monsoon.
