The Secretary-General of the National Water Resources Office has called for continued vigilance after water levels rose more than 2 meters above the riverbanks, following the heaviest rainfall in 300 years. He pointed out that the water management system differs from those in the northern and central regions, causing severe flooding, and recommended dredging Khlong R.1 and Khlong U Taphao.
On 25 November 2025 GMT+7, at the Government House, Mr. Danucha Pichayanan, Secretary-General of the National Water Resources Office, discussed the flooding situation in Hat Yai District, Songkhla Province, highlighting differences from flood areas in central and northern Thailand. He explained that Songkhla's water management relies on canals for drainage, and the situation worsened compared to previous floods due to accumulated heavy rainfall in Sadao District.
Khlong R.1 has a capacity of 1,200 cubic meters, which is insufficient for the accumulated rainfall of 880 millimeters per hour. Continuous rain in the surrounding areas has overwhelmed the canal system's capacity to drain water. Mr. Danucha acknowledged that this is the heaviest rainfall in 300 years and recommended future water management measures, including deepening Khlong R.1 and expanding Khlong U Taphao to better handle such rare events.
He also revealed that the Prime Minister emphasized prioritizing life-saving efforts, mobilizing all resources to assist in the affected areas. Today, monitoring continues as the Meteorological Department forecasts more heavy rain in Hat Yai District. Recent observations between 11:00 and 13:00 showed that water levels rose an additional 2.2 meters following last night's rainfall, making ongoing vigilance essential for local residents.
