Bangkok Declared Disaster Zone as Severe Flooding Disrupts Thailand’s Capital

September 26, 2026

Bangkok has been declared a disaster-affected zone after torrential rain caused widespread flooding across Thailand’s capital. Authorities said nearly 300 millimetres of rain fell within 48 hours, leaving major roads underwater and forcing residents to move through deep floodwater.

All 50 Districts Affected

Bangkok authorities declared the disaster situation across all 50 districts of the capital. The eastern parts of the city were among the areas hit hardest, while neighborhoods close to canals faced particularly serious flooding.

Bangkok Governor Chadchart Sittipunt warned that the situation could threaten lives and damage both public and private property.

Heavy Rain Causes Major Disruption

Continuous rainfall since Thursday has flooded roads, canals, homes and businesses. Several vehicles became partly submerged, while some residents were forced to wade through knee- or waist-high water.

Thailand’s meteorological authorities have warned that more thunderstorms and heavy rain could affect the country over the weekend, raising concerns that flooding could continue.

Emergency Shelters Opened

The Thai army has been assisting with relief operations, including setting up shelters and field kitchens. The Bangkok Metropolitan Administration has also designated schools as temporary accommodation for people affected by the flooding.

Residents living near canals have been advised to move important belongings and vehicles to higher ground and avoid unnecessary travel.

Airport Continues Normal Operations

Despite the flooding, Bangkok’s main Suvarnabhumi Airport continued to operate normally. However, tourism authorities advised travellers to allow an additional two to three hours for journeys because of difficult road conditions and possible delays.

Flooding Situation Being Closely Monitored

Authorities are working to remove floodwater while monitoring canals and drainage systems. Officials have said the situation could improve if significant additional rainfall does not occur.

Thailand’s disaster authorities have also warned of potential flash floods, mudslides, forest runoff and river overflow in parts of the country.

Conclusion

Bangkok is facing a major flooding emergency after exceptionally heavy rainfall affected all parts of the capital. Emergency teams, the military and city authorities are working to provide shelter and assistance while weather officials continue to monitor further rainfall.

The coming days will be important as authorities assess whether water levels fall or additional rain causes further disruption.
