Authorities expect a new round of heavy rain on 23-27 September 2026 and plan to release up to 1,800 cubic metres per second from the Chao Phraya Dam. Water levels below the dam could rise 0.7-1.7 m, putting low-lying areas outside the river embankments at risk. Watch flood alerts for Phra Nakhon Si Ayutthaya, Ang Thong, Sing Buri and Chai Nat (9 districts), and for Bangkok and Samut Prakan, where canals are being drained. If your premises, stock or delivery routes are in these areas, move stock up and check your flood plan this week.
