Thailand faces widespread thunderstorms and heavy rain as the monsoon affects multiple regions, prompting warnings of flash floods and strong coastal waves.
The Meteorological Department (TMD) warns residents to prepare for flash floods and water accumulation, particularly in low-lying areas and near foothills. Mariners are advised to navigate with caution, especially in areas prone to thundershowers, as waves in the upper Andaman Sea are expected to reach 2 metres, rising higher during storms.
