ONWR Monitors New Rainfall Forecast for Late August
The Office of the National Water Resources (ONWR) is preparing for increased rainfall in the Nan and Mekong river basins from August 29 to September 1, 2026.
According to a report by Prachachat Business, the Office of the National Water Resources (ONWR) has issued a notice regarding a new wave of rainfall expected between August 29 and September 1, 2026. The agency anticipates a significant increase in precipitation, particularly affecting the Nan river basin and the Mekong river basin in the northeastern region of Thailand.
For residents and travelers, this development is significant as it may lead to increased water levels in these specific river basins. The ONWR is currently focusing on enhancing its forecasting and early warning systems to manage potential water flow from upper regions. Additionally, the agency is monitoring the central Isan and central regions to assess potential impacts.
These measures are part of a broader effort to manage water resources effectively, including planning for the upcoming 2026/2027 dry season. While the ONWR is actively preparing for these weather conditions, the exact intensity of the rainfall and the specific areas that may experience flooding remain to be confirmed. Those living near or traveling to the Nan and Mekong river basins are advised to stay updated on local weather reports and official announcements from the ONWR as the dates approach.
