ONWR Issues Heavy Rain and Flash Flood Warning for Southern Thailand
The Office of the National Water Resources (ONWR) has issued a warning for 10 southern provinces to prepare for heavy rainfall and potential flash floods between October 23 and 26, 2026.
According to a report by Matichon Online, the Office of the National Water Resources (ONWR) has alerted residents and visitors in Southern Thailand to prepare for severe weather conditions. From October 23 to October 26, 2026, ten provinces in the southern region are expected to experience heavy rainfall, which may lead to flash floods and water runoff.
For residents and travelers, this weather alert is significant as it may impact local travel plans, outdoor activities, and road safety in the affected areas. Heavy rain can lead to sudden changes in water levels, making low-lying areas or mountainous regions particularly vulnerable to flooding. It is advised that those currently in or planning to visit the southern provinces monitor local weather updates closely and follow instructions from provincial authorities.
While the ONWR has identified the timeframe and the general region at risk, specific districts or municipalities that may be most severely impacted have not been detailed in this initial warning. Travelers should maintain contact with their accommodation providers or tour operators for the latest information regarding local conditions. As this is a developing weather situation, further updates from the Thai Meteorological Department and local disaster prevention offices remain necessary to confirm the exact scope of the impact.
