The government is preparing to evacuate people in Surat Thani, Nakhon Si Thammarat and Phatthalung who are at risk of landslides and flash flooding.
Apparently the plan was put in place as it is forecast that a north east monsoon moving across the Gulf of Thailand would hit southern coastal provinces over the next few days. The monsoon trough lies across the lowermost part of southern Thailand. That means heavy rain is likely in many areas of the South.
Temperatures have also dropped several degrees over the past few days.
In Surat Thani, the water level in the Tapee River is at 5.95 metres, 45 cm higher than the river's crisis level. Run-off from the river in the next three to four days could cause flooding in six districts of Surat Thani: Muang, Wiang Sa, Khian Sa, Ban Na Doem, Ban Na San and Phunphin districts.
Heavy rains have already been falling for several hours today in many southern areas.
