The National Water Resources Office (สทนช.) warns the Mekong could rise 2.0–4.8 m between 31 Aug and 6 Sep 2026, with water above critical levels at Nong Khai (0.28 m over, 2–4 Sep peak) and Bueng Kan (1.22 m over, 2–5 Sep peak). Low-lying areas in Nong Khai, Bueng Kan, Nakhon Phanom and Mukdahan are at risk of flooding, and some Thai tributaries may drain poorly into the river. If your shop, warehouse, stock or transport runs in these districts, move goods above ground level, check access roads, and follow provincial alerts. Rain is also expected to rise across several regions from 3–6 Sep.
