Thailand Raises Flood Alert for Central Region and Chao Phraya Basin
Thailand has escalated flood preparations for the central region and Chao Phraya basin ahead of expected heavy rainfall September 24–27, with a 24-hour war room coordinating response efforts across affected provinces.
The government has escalated monitoring of the central region and Chao Phraya basin to prepare for heavy rainfall and flooding. Deputy Prime Minister Songsak Thongsri has instructed relevant agencies to ensure readiness in forecasting, water management, equipment deployment, and public care. The Disaster Prevention and Mitigation Department has opened a 24-hour war room to coordinate response efforts from September 24–27, 2025, when severe rain is expected across the central plains, Bangkok, and surrounding areas. Citizens in low-lying and regularly flood-prone zones are urged to monitor weather forecasts and official warnings closely. The National Water Resources Office is coordinating with agencies to track rainfall and water levels in the Chao Phraya basin, particularly in low-lying areas downstream of the Chao Phraya Dam in Chainat, Singburi, Ang Thong, Ayutthaya, and Pathum Thani provinces. Inspection of embankments, drainage routes, and water obstruction removal is underway, with personnel and equipment being mobilized for rapid deployment if needed. The Royal Irrigation Department continues managing water flow in the basin, releasing 1,750 cubic meters per second through the dam as of 6 a.m. on September 25, 2025, while channeling water to eastern and western irrigation systems. Twelve water pumps have been deployed since mid-September across Nakhon Pathom, Chachoengsao, Suphan Buri, and Samut Sakhon provinces. The Disaster Prevention and Mitigation Department has coordinated with 70 provinces and Bangkok, with regional centers pre-positioning machinery and personnel across affected areas. Ayutthaya province has mobilized troops and volunteer territorial defense members to reinforce embankments and prepare shelters and medical units, while Pak Hai district units are monitoring water levels and assisting vulnerable populations. All agencies remain on heightened alert with water management systems, early warning systems, and rescue teams ready to support communities should flooding occur.
