WEDNESDAY, SEPTEMBER 17, 2025

The Department of Disaster Prevention and Mitigation (DDPM) on Wednesday sent a Cell Broadcast alert warning of increased discharge from the Chao Phraya Dam, urging residents in eight districts to move belongings to higher ground.

The department said the Chao Phraya Dam would increase its discharge to no more than 2,500 cubic metres per second, up from 2,100 cu m/s at 11am on September 17.

The higher discharge is expected to lift water levels by about 10–30 centimetres in low-lying areas outside flood barriers in parts of Chainat, Sing Buri and Ang Thong.

Affected areas include Sapphaya district in Chainat; In Buri, Mueang Sing Buri and Phrom Buri in Sing Buri; and Mueang Ang Thong, Wiset Chai Chan, Pa Mok and Chaiyo in Ang Thong, along with adjacent communities.

Residents in low-lying zones outside floodwalls are advised to move belongings to higher ground, look after vulnerable groups such as the elderly and bed-bound patients, and follow local official updates closely.

DDPM added that, together with mobile operators Advanced Info Service (AIS), True and National Telecom (NT), it has sent Cell Broadcast alerts to residents in the affected areas.

Incidents and assistance requests can be filed via the Line account @1784DDPM or by calling the DDPM 1784 hotline, 24 hours.
