Bangkok floods: 40 dead as heavy rains paralyze Thai capital

• About 40 people have died in flood-related incidents in Bangkok.
• Thousands of residents are in over 230 flood shelters.
• Approximately 300mm of rain fell in parts of Bangkok over two days.
• Flooding disrupted operations at Bangkok's Suvarnabhumi airport.
• The government declared a flood disaster across all 50 of Bangkok's districts.

Bangkok has been inundated by severe flooding following relentless rainfall that has transformed streets into stagnant lakes, causing widespread disruption and loss of life. The deluge, which saw approximately 300mm of rain fall in about two days in some areas – equivalent to half a year's average rainfall in London – has overwhelmed the city's drainage systems.

Authorities reported about 40 deaths related to the floods, including drownings and accidental electrocutions. Thousands of residents have been forced into more than 230 shelters across the capital. The flooding has also impacted critical infrastructure, with disruptions at Bangkok's main Suvarnabhumi airport leading to flight cancellations and a significant backlog of luggage. Many schools have also closed.

Residents described the rain as constant, falling all day and night, with water levels rising rapidly. Suleemas Kurangkul, a 73-year-old resident of the Khlong Chan flat compound, noted the strong smell of debris and rubbish floating in the water once it began to recede. The city, built on a floodplain, relies on a network of canals and pumps for drainage, but extensive concrete construction has degraded this system, leaving it unable to cope with extreme weather events.

Thailand's Prime Minister Anutin Charnvirakul stated that the metropolitan area remains at risk from floodwaters flowing from the north and that a war room has been established to monitor the situation. The weather agency has forecast more heavy rain for the upcoming week. Scientists attribute the worsening extreme floods in Southeast Asia to climate change, driven by fossil fuel pollution.
