Alert: High Tidal Surge Expected May 17-21, Seven Provinces Face Flooding Risk on Major Roads
High tidal surge expected May 17-21 will raise water levels along major rivers, threatening flooding on key roads and low-lying areas across seven central provinces including Bangkok and Samut Prakan.
The Department of Natural Resources Water Administration issued a warning on May 14 about high tidal conditions expected between May 17-21. Southern winds and southwest monsoon winds over the Andaman Sea and Gulf of Thailand will intensify waves, raising water levels at river mouths and potentially causing flooding in low-lying areas along the Chao Phraya, Mae Klong, and Tha Chin rivers. Communities outside flood barriers and major roads including Sukhumvit, Suksawat, and Rama II roads are at particular risk. Saltwater intrusion poses additional concerns for drinking water quality and agricultural areas. Relevant agencies are urged to monitor conditions in Samut Prakan, Bangkok, Nonthaburi, Pathum Thani, Samut Sakhon, Nakhon Pathom, and Samut Songkhram provinces.
