The Thai Meteorological Department said the storm, which has been named “Rai” and affected Mukdahan, Amnat Charoen and Ubon Ratchathani Tuesday, would weaken to become a tropical depression moving over the middle Northeast, the lower North and the upper Central area.
The department urged people in affected areas to expect severe conditions and follow its weather updates.
The Andaman Sea and upper Gulf of Thailand were roiled by three-metre waves so ships should proceed with caution and small boats keep ashore until next Monday, the department said.
