People in eight southern provinces are warned to prepare for torrential rain from Thursday to Sunday with possible flooding, forest runoff and landslides.
The high pressure system over China is forecast to expand and cover upper Thailand on Thursday, Kamol Phromsaka Na Sakolnakorn, director of the Southern-east Coast Meteorological Centre, said on Tuesday.
The system will strengthen the monsoon trough that prevails over the South and the Gulf of Thailand, until Sunday.
During this period, eight provinces in the region are expected to experience heavy rain – Chumphon, Surat Thani, Nakhon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala and Narathiwat.
Residents are warned to prepare for possible flash floods, forest runoff and landslides in risk areas. Winds in the Gulf of Thailand will intensify, with waves up to two-metres high.
“People should closely follow the updates from the Meteorological Centre,’ Mr Kamol said.
On Monday, many roads on the southern island of Phuket were left flooded after heavy rain in the morning.
