- Traffic expected to normalize in 2 days, while communities need 2 weeks to dry
Bangkok Governor Chadchart Sittipunt provided an update on the heavy rain and flooding situation in the capital on September 27 at 09:20 AM at Don Mueang International Airport. He stated that the overall situation is showing signs of improvement as the low-pressure system that previously hovered over central Bangkok has now shifted away, resulting in a noticeable decrease in local rainfall.
Over the past few days, Bangkok has experienced intense downpours that overwhelmed drainage systems and caused canals to overflow onto the streets. The massive volume of water required urgent drainage operations, which included key operational figures such as:
- A cumulative rainfall of up to 320 millimeters across Bangkok
- An estimated 200 to 300 million cubic meters of water requiring drainage
- The Thonburi side remaining secure with efficient water drainage capacity

Regarding current weather patterns, the Governor noted that the low-pressure cell has moved towards Myanmar, shifting the heavy rain bands to Kanchanaburi and Ratchaburi provinces instead. Meanwhile, rainfall in Bangkok is expected to drop to just 10 to 20 millimeters per day. However, city authorities remain vigilant and are closely monitoring all critical areas, particularly locations situated along canals where water levels require continuous observation.
Water management in Bangkok remains a critical operational challenge during the monsoon season due to the city's low-lying geography and heavy reliance on canals and drainage tunnels. A rainfall accumulation of 320 millimeters within a short timeframe pushes municipal infrastructure to its limits, as main canals quickly reach full capacity. The departure of the low-pressure system is therefore a vital turning point in easing the capital's flood mitigation workload.
Concerning the recovery timeline, Governor Chadchart estimated that main road traffic will return to normal within two days. However, residential communities and neighborhoods experiencing inundation will require up to two weeks for complete drainage and dry conditions. The Thonburi side remains a lower-risk zone due to its faster and more efficient drainage response capabilities.
