Three people have drowned and a fisherman is missing as heavy rain pounds the southern provinces, with floods affecting thousands of people.
In Surat Thani, the worst-hit province, high water made the main road around the popular tourist island of Koh Samui impassable. Heavy rain was also delaying some flights at Samui Airport.
In Kanchanadit district, Natthaphol Manajak, 6, from Nakhon Si Thammarat, drowned in floodwaters on Nai Lai Road in tambon Tha Uthae, said Jamnong Sawasdiwong, chief of the provincial disaster mitigation office.
