Bangkok declared all 50 districts disaster zones after days of nonstop rain.
Why it matters: The flooding is disrupting transport, commerce and daily life in Thailand's capital. As a major Southeast Asian hub, Bangkok's drainage crisis can ripple through residents, businesses and regional operations.
- Bangkok authorities declared all 50 districts a disaster zone on Saturday, Sept. 26, 2026.
- Governor Chadchart Sittipunt said nearly 300mm of rain had fallen since Thursday afternoon.
- City officials said floodwaters should start receding when rain stops, but may take two to three days to drain.
- Bangkok's public transport authority is offering free MRT 'park and ride' access through Oct. 2.
Bangkok authorities declared all 50 districts of the Thai capital a disaster zone after three straight days of rain triggered widespread flooding, according to reporting from the city.
Governor Chadchart Sittipunt said nearly 300mm of rain had fallen since Thursday afternoon, with the eastern areas of Bangkok among the hardest hit. He said the rain was still falling and warned that people living near canals faced the biggest risk because the waterways were already full.
Floodwaters swamped roads and canals and pushed water into homes and shops across the capital. Photos and video from the city showed abandoned vehicles on submerged streets.
Officials said the water should begin to recede once the rain stops, but later warned drainage could still take two to three days if no more rain falls. Bangkok's public transport authority said it would offer free access to MRT park and ride facilities through Oct. 2 so residents can move vehicles to higher ground.
Thailand's government had already warned on Sept. 23 that heavy to very heavy rain was expected across much of the country, including Bangkok, through Sept. 27, according to an official statement. Reuters reported that Chadchart said the flooding "poses a risk to people's lives ... as well as damage to public and private property."
Bangkok is a low-lying, flood-prone metropolis, and drainage remains a recurring policy issue for City Hall.
By the numbers
- 50 - Bangkok districts declared disaster zones
- Nearly 300mm - Rainfall cited by Governor Chadchart since Thursday afternoon
- 2-3 days - Estimated time for floodwaters to drain if rain stops
Yes, but: Officials said flooding should ease once rain stops, but they warned drainage could still take days if showers continue.
What's next: City officials are watching for rainfall to stop and for floodwaters to begin receding over the next two to three days. MRT park-and-ride access remains free through Oct. 2.
