Agriculture ministry has ordered close monitoring of flood risk in 12 provinces, including Chiang Rai, Chiang Mai, Nan, Phitsanulok, Udon Thani and Ubon-adjacent Amnat Charoen. Flash floods and overbank flows are expected in hilly and low-lying areas through mid-August 2026. The R.1 canal in Songkhla, the main drainage route for Hat Yai's economic area, is targeted to be fully operational again by November 2026 ahead of southern rains. If your business sits in these provinces or in Hat Yai, plan stock, transport and equipment protection now, and expect possible disruption to deliveries and access.
