Heavy to very heavy rain is forecast to hit 12 southern provinces from Sunday as a low-pressure cell covers the Malacca Strait and strong easterly and northeasterly winds prevail across the South and the Gulf of Thailand, the Thai Meteorological Department announced in its 5am forecast on Sunday.
The 12 provinces are Surat Thani, Nakhon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala, Narathiwat, Phangnga, Phuket, Krabi, Trang and Satun.
People should beware of severe weather conditions along with overflows and flash floods.
Because of the strong winds, waves are expected to be 2 metres high in the upper Gulf of Thailand, 2-3m high in the lower Gulf of Thailand - more than 3m high in thundershowers - and 1-2m high in the Andaman Sea.
People in coastal areas on both sides of the South are advised to beware of storm surges.
All boats should proceed with caution and avoid thundershowers while small boats in the Gulf of Thailand should stay ashore, the department announced.
