Footage shows locals wading through severe floods in southern Thailand.

Intense rainfall continues to overwhelm communities in Yala and Songkhla provinces, near the border with Malaysia, following widespread rain on November 27.

Authorities reported that more than 100 households were forced to evacuate as floodwaters reached 1.5 metres in the Hat Yai district's Ban Phru Moo 8 village.

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 temperatures 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).
