The National Water Resources Office (สทนช.) says a new rain wave is expected 4-7 October. Chao Phraya lower-basin fields hold 553 million m³ (69% of plan) and the Chao Phraya dam is releasing 2,500 m³/s to lower levels before easing back to about 700 m³/s. Mae Klong releases are falling to about 1,600 m³/s. Samut Songkhram flooding threatens pomelo orchards in Bang Khanthi and Amphawa. If your premises, stock, deliveries or farms sit in Ayutthaya, Ang Thong, Nakhon Sawan, Samut Songkhram or low-lying Bangkok fringe areas, check access routes and move valuables and inventory up now. Watch official alerts for Prachinburi and Chachoengsao flows too.
