Severe floods sparked road closures as heavy rain continued to lash southern Thailand today.

Intense rains spawned flooding that submerged farmlands and triggered landslides in the Betong district of Yala province on November 27.

Authorities patrolled affected areas and stationed personnel to warn motorists of dangerous road conditions.

The Ban Wang Mai–Skywalk Iyerweng road was temporarily closed after part of it collapsed into a 70ft (20m) cliff.

Betong district chief Amorn Chumchuay warned residents to remain vigilant against flash floods, overflows, landslides, and heavy winds from November 27 to December 4. He urged locals, especially those in high-risk areas, to constantly monitor weather and water level updates.

He said: 'Personnel, equipment, and machinery are ready to assist locals promptly during any crisis, including issuing advance warnings. People should stay updated through official government announcements.'

The Thai Meteorological Department (TMD) issued a weather advisory warning of heavy rainfall in the south, strong winds and waves over the lower Gulf of Thailand, and cool to cold weather in the upper part of the country.

The department reported that a moderate to rather strong high-pressure system from China would extend over upper Thailand and the South China Sea.

The northeast monsoon prevailing over the Gulf of Thailand and the South was expected to strengthen, while an active low-pressure cell over the lower South China Sea would move through the lower South and Malaysia into the lower Andaman Sea.

Heavy to very heavy rains were predicted in several southern provinces, including Songkhla.

The TMD urged residents in affected areas to be cautious of flash floods and overflows, especially near waterways, foothills, and low-lying areas.

The strengthening winds were expected to cause waves in the upper Gulf and the Andaman Sea to reach about 6.6 feet (2 metres) and exceed 6.6 feet (2 metres) in thundershowers.

In the lower Gulf, waves were forecast to rise between 6.6ft and 9.8ft, exceeding 9.8ft (3m).
