Bangkok: The Department of Disaster Prevention and Mitigation (DDPM) has taken proactive measures by coordinating with 10 central provinces, including Bangkok, to monitor the rising water levels in the Chao Phraya River from August 27 to September 2, 2026. The DDPM has issued directives to officials to keep a vigilant watch on the water situation, particularly in low-lying areas outside the flood barriers. Residents living along the Chao Phraya River have been advised to remain vigilant and prepare for potential flooding, with public announcements and warnings being disseminated to ensure their safety.
According to Thai News Agency, the DDPM, in its capacity as the Central Disaster Prevention and Mitigation Command (CDPMC), received a notification from the Royal Irrigation Department regarding the Chao Phraya River Basin water situation. The notification, labeled Warning No. 1, provides a forecast for the next 1-9 days. On August 28, 2026, the water flow at station C.2 in Mueang Nakhon Sawan District, Nakhon Sawan Province, is expected to reach approximately 1,000-1,100 cubic meters per second. Additionally, water volume from tributaries is projected at approximately 60-100 cubic meters per second, resulting in a total water volume upstream of the Chao Phraya Dam of between 1,100-1,200 cubic meters per second. Consequently, water will be released downstream of the Chao Phraya Dam at a rate of between 700-1,000 cubic meters per second. This increase in water level is expected to raise water levels by approximately 0.60 - 1.5 meters in low-lying areas outside the flood barrier in specific districts of Phra Na khon Si Ayutthaya province, although it will not impact community areas.
The CDPMC has engaged with the central provinces of Uthai Thani, Chai Nat, Sing Buri, Ang Thong, Suphan Buri, Phra Nakhon Si Ayutthaya, Lop Buri, Pathum Thani, Nonthaburi, Samut Prakan, and Bangkok to ensure a coordinated response. Warnings have been issued to relevant agencies and private businesses along the rivers, including those involved in riverbank construction, floating restaurants, and public passenger piers. Residents along the riverbanks and in vulnerable low-lying areas have been advised to prepare for rising water levels by moving belongings to higher ground. Local administrative organizations and relevant agencies in affected areas have been instructed to inspect and strengthen flood barriers and defense systems. Disaster relief equipment and machinery are being prepared to provide round-the-clock assistance to the public.
Residents in the affected areas are urged to monitor official news, adhere strictly to instructions, and prepare for potential disasters. In case of hardship resulting from a disaster, assistance can be requested via the LINE account 'DDPM Emergency Reporting 1784' or the emergency hotline 1784, both available 24 hours a day.
