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. Water levels were currently stable.
Relief operations involve the Bangkok Metropolitan Administration, DDPM, the Drainage and Sewerage Department, district offices, military units, police, local authorities, civil defence volunteers, other volunteers and foundations.
Teams are assisting residents, managing traffic and accelerating drainage from flooded areas. Authorities have also opened 233 temporary shelters.
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.
Businesses including riverbank construction sites and floating restaurants have been told to monitor conditions closely.
Chao Phraya Dam is expected to release 1,500–2,000 cubic metres per second over the next one to nine days, which could raise downstream water levels by approximately 0.70–1.70 metres.
The Thai Meteorological Department reported that in the 24 hours to 1am on September 29, the highest rainfall in Bangkok and surrounding areas was 42.4mm at Suvarnabhumi Airport in Bang Phli district, Samut Prakan, classified as heavy rain.
Rainfall is expected to ease overall, although very heavy rain remains possible in some areas, particularly in the western North.
Parts of the Central region and East may also continue to experience heavy rain.
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.
