Hat Yai:Bangkok The Royal Irrigation Department is taking measures to monitor and prepare for heavy rainfall expected in southern Thailand from October 24 to 26. This comes after Krabi province recorded 100 millimeters of rainfall over a 24-hour period.
According to Thai News Agency, the department has installed water pumps and propulsion systems in high-risk areas. Additionally, the R.1 drainage canal in Hat Yai district, Songkhla province, has been confirmed to have a capacity of 1,200 cubic meters per second.
Director-General Witthaya Kaewmee stated that following the National Water Resources Office's announcement of a flood watch for flash floods, landslides, and river overflows from October 23-26, 2026, the department is closely monitoring the situation in 10 high-risk southern provinces including Ranong, Phang Nga, and Phuket.
Special attention is being given to urban and economic hubs like Bang Saphan District, Chumphon city, and Hat Yai District, where flooding could have significant impacts. The department is working with local organizations to improve drainage and remove obstructions from waterways.
In Hat Yai, the department has enhanced the R.1 drainage canal using central government funds. Despite incomplete asphalt surface improvements, structural repairs have been made, allowing the canal to handle increased water flow. Furthermore, water hyacinths obstructing waterways are being removed to ensure improved drainage.
The latest reports indicate continued rainfall in the South, with Krabi province recording the highest recent rainfall. Reservoirs in the region are at 69% capacity, and the National Water Resources Management Committee advises monitoring reservoirs in six provinces and riverbanks along several rivers for potential overflows.
