Chadchart acknowledged that although rainfall in Bangkok has decreased, all areas still require close monitoring, especially along canals. He expects traffic to return to normal within two days, but fully drying out flooded communities will take two weeks. He noted that the Thonburi side is less worrisome due to faster drainage.
At 09:20 on 27 Sep 2026 GMT+7 at Don Mueang Airport, Chadchart Sittipunt, Governor of Bangkok, commented on the rain and flooding situation in Bangkok. He said the situation has improved because the low-pressure area over central Bangkok, which caused heavy rain, has shifted. In the past 2-3 days, rainfall reached as much as 320 millimeters, comparable to levels in Hat Yai District, Songkhla Province. There is 200-300 million cubic meters of water that needs urgent drainage, causing canals to fill and overflow onto various roads.
Today, the low-pressure area has moved toward Myanmar, causing rain over Kanchanaburi and Ratchaburi provinces instead. In Bangkok, rainfall will reduce to 10-20 millimeters per day. Areas near canals will gradually improve, but drainage cannot be swift because even though water is drawn from the canals, nearby water flows back in. However, side areas will slowly drain, which will take several more days. Positively, in flooded communities such as the Romklao Housing Community, which has over 30,000 residents and was severely flooded on 26 Sep, many wanted to evacuate. Evacuation centers were set up within the community but became overcrowded with thousands arriving, so evacuees were relocated to King Mongkut's University of Technology Ladkrabang.
The main issue now is caring for those still in large flooded communities, estimated to number in the tens of thousands. Authorities must provide food and care, including for bedridden patients; about 40-50 have been evacuated so far, but some remain and need urgent assistance. A full list of those affected has been compiled.
When asked if any areas require special monitoring, Chadchart said all locations with flooding problems do, especially areas near canals such as Khlong Saen Saep in Bang Kapi, Khlong Prem Prachakorn in Lak Si, and Khlong Prawet in Lat Krabang and Suan Luang districts. These must be closely observed.
Asked if inner city flooded areas can drain today, Chadchart said some areas like Ekkamai are beginning to dry. The concern is outer areas such as Bang Kapi, On Nut, and Ramkhamhaeng. For communities to be completely dry, it will likely take two weeks. Main roads should improve in 2-3 days. Therefore, government agencies are advised to allow work-from-home where possible. Although main roads are passable, some flooded spots may cause bottlenecks. Reducing travel will ease traffic congestion. Bangkok authorities have declared work-from-home for civil servants not serving the public, and all 400+ Bangkok schools will close on 28 September for one day.
When asked about concerns over heavy rain shifting to the Thonburi side today, Chadchart said it is not worrisome because drainage there is efficient and fast.
When asked about reports and the number of fatalities from this event, Chadchart said he has not received any such reports.
Chadchart said the Prime Minister has ordered all agencies to cooperate. On 26 September, several ministers visited the Bangkok operations center to work together. The Defense Minister brought a GMC vehicle to Lat Krabang as part of the efforts.
