The authorities are on high alert as Tropical Storm Pabuk is on course for southern Thailand.
Chayaphon Thitisak, Disaster Prevention and Mitigation Department director general, said his southern offices were prepared for the storm later this week.
The authorities are stockpiling equipment and supplies, he added.
Chayaphon urged citizens to stay alert and comply with the official instructions.
In case of an emergency, people can call the 1784 hotline.
The Meteorological Department says Pabuk will affect Thailand until Saturday, as it is now moving westward at the speed of 10 kilometres per hour and it is already entering the Gulf of Thailand.
A warning for heavy downpours and strong gale has been issued for Phetchaburi, Prachuap Khiri Khan, Chumphon, Surat Thani, Nakhon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala, Narathiwat, Ranong, Phangnga, Phuket, Krabi, Trang and Satun.
The Meteorological Department also urged Gulf coast southerners to stay away from the shore as waves of 3-5 metres were expected with a chance of inshore surges.
