The Department of Disaster Prevention and Mitigation (DDPM) has issued a warning to Bangkok and 10 central provinces to brace for a significant rise in water levels along the Chao Phraya River, expected from 31 July onwards.

 

The affected provinces Uthai Thani, Chai Nat, Sing Buri, Ang Thong, Suphan Buri, Phra Nakhon Si Ayutthaya, Lop Buri, Pathum Thani, Nonthaburi and Samut Prakan. The DDPM has instructed provincial authorities to closely monitor water levels, particularly in low-lying areas outside flood barriers and to coordinate with local agencies to inspect flood defences and prepare emergency equipment.

 

According to DDPM Director-General Mr. Phasakorn Boonyalak, data from the Royal Irrigation Department forecasts that water flow at the C.2 Station in Nakhon Sawan Province will reach between 1,500 and 1,900 cubic metres per second on 31 July. With an additional 150–200 cubic metres per second from tributaries, upstream water volume entering the Chao Phraya Dam is expected to rise to 1,650–1,850 cubic metres per second.

 

To manage this surge, water will be discharged downstream at a rate of 1,200–1,500 cubic metres per second. This is likely to cause water levels in vulnerable zones, including Phong Pheng Canal in Ang Thong, Bang Ban Canal and areas such as Hua Wiang, Lat Chid and Tha Din Daeng in Ayutthaya Province, to increase by 20 centimetres to 1 metre.

 

In response, the DDPM has urged local governments and disaster relief agencies to remain on high alert, strengthen embankments, and ensure that flood-response machinery is operational 24/7. The public, particularly those living along riverbanks, is advised to move belongings to higher ground and stay informed.

 

Residents, businesses, riverside restaurants, construction projects and floating facilities are all advised to take precautions. The DDPM emphasised the importance of ongoing updates via the Thai Disaster Alert (TDA) app, available on both iOS and Android, and through its official social media accounts: Facebook (กรมป้องกันและบรรเทาสาธารณภัยDDPM) and X/Twitter (@DDPMNews).

 

Those experiencing emergencies can request assistance via the DDPM’s Line account (@1784DDPM) or by dialling the 24-hour hotline 1784.
