NationThailand-Sept 29
Flooding remains active across 29 provinces and Bangkok, affecting more than 2.6 million people, while the cumulative death toll since September 16 has risen to 23, according to the Department of Disaster Prevention and Mitigation (DDPM).
In its situation report issued at 6am on Tuesday (September 29, 2026), the department said flooding continued across 167 districts, 890 subdistricts and 5,077 villages, affecting 940,300 households and 2,602,309 people. Since September 16, a total of 42 provinces and Bangkok have experienced flooding. DDPM reported 23 deaths and no injuries. Water levels were rising in 14 provinces, stable in six provinces and Bangkok, and falling in nine provinces. Bangkok has experienced severe flooding since September 25 following prolonged heavy rain. DDPM said approximately 329,000 households, or around 700,000 people, had been affected. Four deaths were reported, with no injuries or missing persons. The Central Disaster Prevention and Mitigation Command has issued its fifth warning on the Chao Phraya basin, instructing provinces and Bangkok to alert government agencies, businesses operating along rivers and canals, and riverside communities. Chao Phraya Dam is expected to release 1,500–2,000 cubic meters per second over the next one to nine days, which could raise downstream water levels by approximately 0.70–1.70 meters. The department said a low-pressure system over the Gulf of Martaban had moved over the coast of Myanmar, while the south-westerly monsoon over the Andaman Sea, South and Gulf of Thailand was weakening. Residents were nevertheless advised to remain alert for flash floods, forest run-off and landslides, particularly around foothills near waterways and in low-lying areas.
