Outbreaks of rain and isolated heavy downpours are likely to hit the North, Northeast, Central, East and South regions today, the Meteorological Department has warned.
The bad weather conditions are being brought about by the monsoon trough lying across the upper North and the upper Northeast, the active low pressure over the South China Sea and the strong southwest monsoon across the Andaman Sea, Thailand and the Gulf of Thailand.
Therefore, people in all regions are advised to brace for possible flash floods, overflows and landslides.
Provinces likely to be affected are:
The North: Chiang Rai, Phayao, Phrae, Nan, Tak, Uttaradit and Phetchabun;
The Northeast: Nong Khai, Bung Kan, Sakon Nakhon, Nakhon Phanom, Mukdahan, Amnat Charoen and Ubon Ratchathani;
The Central: Kanchanaburi, Uthai Thani, Chai Nat, Nakhon Sawan, Lop Buri and Saraburi;
The East: Nakhon Nayok, Chachoengsao, Prachin Buri, Sa Kaeo, Chon Buri, Rayong, Chanthaburi and Trat; and
The South: Chumphon, Surat Thani, Nakhon Si Thammarat, Ranong, Phangnga, Phuket, Krabi, Trang and Satun.
Waves will be 2-3 metres high in the Andaman Sea, 2 metres high in the upper Gulf of Thailand and 3 metres high in areas with thunderstorms. Fishing boats should proceed with caution while small boats should stay ashore.
People in the western and eastern coasts of the South should also beware of inshore surges.
