In neighbouring north Malaysia, the rains have forced the evacuation of at least 80,000 people to temporary shelters this week, with disaster officials there saying at least four people have been killed.
The Thai Meteorological Department has warned that “very heavy rain” could continue to affect some areas of the country’s south through next week.
The government has deployed rescue teams to assist affected residents and designated 50 million baht (US$1.7 million) in flood relief for each province.

While Thailand experiences annual monsoon rains, scientists say man-made climate change is causing more intense weather patterns that can make destructive floods more likely.
Widespread flooding across the country in 2011 killed more than 500 people and damaged millions of homes.
