There will be heavy to very heavy rain in Thailand from Thursday to Monday next week, according to the Meteorological Department.
Sugunyanee Yavinchan, director-general of the department, said on Wednesday that the North, the Central Plains, the East and the South would see heavy to very heavy rain. Flash floods and run-off can occur, especially on slopes, in waterways and in low-lying areas during the period.
She attributed the forecast to an active low-pressure system moving to the upper Bay of Bengal, while the southwest monsoon strengthens over the Andaman Sea, Thailand and the Gulf of Thailand.
From Thursday to Monday, waves in the Andaman Sea will reach two to three metres and exceed three metres in thundershowers. Ms Sugunyanee advised small boats be kept ashore during the period.
