Nine Bangkok roads remain flooded as rain eases and pumping continues
Rainfall is easing in Bangkok, but nine roads remain flooded while the city accelerates drainage in four main canals and reopens parts of five roads.
- Nine major roads in Bangkok remain heavily flooded following recent rainfall, despite the weather showing signs of easing.
- The city administration is continuing extensive pumping operations to clear the water from the affected areas.
- Efforts are also focused on lowering water levels in four key canals to improve the drainage network's capacity.
Rainfall in Bangkok showed signs of easing on Monday (September 28), but nine major roads remained heavily flooded as the Bangkok Metropolitan Administration (BMA) continued pumping water and lowering levels in four key canals.
The Bangkok Flood Control Centre reported at 6am that light rain was falling over Nong Chok district and moving northeast. The highest accumulated rainfall was recorded in Lat Krabang at 46.5 millimetres.
Skies began to clear after late-night rain moved through the capital, with no large rain bands in nearby provinces detected moving towards Bangkok at the time of the report. However, water remained on several roads while canal levels remained elevated, requiring drainage operations to continue.
Data from the BMA’s Department of Drainage and Sewerage showed that nine roads still had significant flooding, while sections of five other roads had become passable again.
The BMA urged motorists to check conditions before travelling and avoid inundated sections where possible, as pumping operations continued across affected areas.
Nine roads still heavily flooded
The roads and sections requiring particular caution are:
- Ramkhamhaeng Road
- Sena Nikhom Road
- Srinagarindra Road, from Lam Sali intersection to Phatthanakan Road and around Krung Thep Kritha intersection
- Lat Phrao Road, from Pradit Manutham intersection to Happy Land intersection
- Ngam Wong Wan Road, in front of Soi Chin Khet
- Nakkila Laem Thong Road
- Sihaburanukit Road
- Nuan Chan Road
- Phetchaburi Road, from the Phet Uthai Road junction to Khlong Tan intersection
Motorists are advised to check individual road sections before setting out, particularly on Ramkhamhaeng Road, where conditions continue to require close monitoring.
Parts of five roads reopen to traffic
Traffic has resumed along some sections of the following roads:
- Lat Phrao Road, around the Pradit Manutham Road intersection
- Chaeng Watthana Road, from Soi 14 to Khlong Prapa
- Ram Inthra Road, from Lat Pla Khao to Watcharaphon intersection
- Phetchaburi Road, from Uruphong intersection to Nikhom Makkasan intersection
- Nawamin Road, from Soi Nawamin 88 to the Ratchada–Ram Inthra Road junction
The BMA stressed that Lat Phrao and Phetchaburi roads each have sections that are now passable as well as stretches where flooding remains severe. Travellers should therefore check conditions for the specific section they intend to use rather than assume the entire road has reopened.
Bangkok Deputy Governor Wisanu Subsompon reported at 6.30pm on Sunday (September 27) that rainfall was beginning to ease and water levels in some canals had started falling.
Levels had declined along parts of Khlong Saen Saep, helping some previously flooded road sections become passable again.
The BMA is operating pumps at full capacity while managing water levels across both major and secondary canals. The Bueng Makkasan drainage tunnel is also being used to accelerate the discharge of water into the Chao Phraya River.
Eastern Bangkok remains under close watch, particularly areas along Khlong Saen Saep and Khlong Prawet Buri Rom.
The immediate priority is to lower water levels in four major canals — Khlong Saen Saep, Khlong Lat Phrao, Khlong Prawet Buri Rom and Khlong Prem Prachakorn — to create more capacity for water from surrounding areas to drain into the canal network.
With rainfall expected to ease on September 28, the BMA expects drainage operations to continue making progress and water levels to gradually recede.
