Thailand's National Water Resources Office (NWRO) has issued a high-alert warning for a combination of elevated tidal surge (Aug 25–29) and heavy rainfall driven by the southwest monsoon and tropical low-pressure system. The Chao Phraya River's low-lying areas across Bangkok, Nonthaburi, Pathum Thani, and Samut Prakan—especially communities outside flood barriers—face inundation risk. Water reservoir levels nationwide stand at 64% capacity, with the central region at only 37%, underscoring operational vulnerability. SMEs and manufacturers in flood-prone zones should activate contingency plans immediately.
