Bangkok Implements Real-Time Data Analysis to Manage Heavy Rainfall

According to Khaosod Online, the Bangkok Metropolitan Administration (BMA) is deploying real-time data analysis technology to monitor and manage the impact of heavy rainfall forecasted for the capital between September 23 and 27, 2026. Jetsada Chantaraprapha, Director of the Department of Drainage and Sewerage, stated that the city is preparing for increased water discharge from the Chao Phraya Dam, which has been raised to 1,500 cubic meters per second.

To minimize flood risks, the BMA is actively lowering water levels in canals, cleaning drainage pipes, and removing debris from water grates and pumping stations. Temporary pumps are being installed in high-risk areas, including major roads and vulnerable community zones. These measures are part of an ongoing flood prevention strategy designed to improve drainage efficiency.

For residents and travelers, this means that while the city is taking significant steps to prevent flooding, there remains a possibility of localized water accumulation during heavy downpours. It is advisable to monitor local weather updates and traffic reports, as heavy rain can lead to temporary road congestion or disruptions in low-lying areas. While the BMA has established these protocols based on previous flood experiences, the actual severity of the rainfall and the effectiveness of the drainage response in specific neighborhoods remain to be confirmed as the weather system progresses.
