BANGKOK: The Thai Meteorological Department (TMD) said in its 24-hour forecast that rain across Thailand would decrease, although isolated heavy rain would continue on the South’s west coast.
The conditions are being influenced by a moderate southwesterly monsoon covering the upper Andaman Sea and Thailand.
People are advised to beware of heavy rain and accumulated rainfall, which could cause flash floods and runoff, particularly on foothills near waterways and in low-lying areas.
They are also advised to take care of their health during changing weather conditions.
Marine conditions in the Andaman Sea and the Gulf of Thailand are moderate.
Waves in the upper Andaman Sea are about two metres high, while waves in the lower Andaman Sea and the upper Gulf of Thailand are one to two metres high.
In thunderstorm areas, waves are expected to rise above two metres.
Boat operators in these areas are advised to navigate with caution and avoid sailing in thunderstorm zones.
