BANGKOK, 28 September 2026: The Bangkok Metropolitan Administration (BMA) has extended its flood disaster declaration to all 50 districts following heavy rain that has inundated residential areas and disrupted transport across the capital.
The declaration took effect on 25 September and enabled district offices to assess damage and arrange assistance for affected residents.
Rain has continued since Wednesday, with about 300 mm reported in less than two days. Floodwater has reached around 60 cm in some locations. Roads and vehicles have been submerged, while severe congestion has delayed journeys across Bangkok and surrounding areas. Rain continued through the weekend but eased by late Sunday. Passengers heading to the city’s two airports faced long commutes.
Governor Chadchart Sittipunt convened Bangkok’s 50 district offices and relevant agencies on Saturday to coordinate the response. The measures include identifying vulnerable residents and patients who may need assistance, preparing temporary shelters in BMA schools, arranging transport, deploying sandbags and accelerating drainage. District offices have also been instructed to coordinate with traffic police and monitor roads affected by rising water.
The citywide declaration provides a framework for assistance; it does not mean that every district or household has experienced flooding to the same extent. Residents seeking support will need to report damage to their district office for assessment. The BMA has advised affected households to retain photographs and other evidence of damage to homes and possessions.
The flooding had immediate consequences for businesses. Staff were unable to reach workplaces, deliveries were delayed, and employers were told to check conditions before asking staff to travel and make practical arrangements where routes are affected.
Hotels, restaurants and other tourism businesses face similar operational difficulties. Guests need accurate advice about journeys to and from properties, particularly when travelling with luggage or working to a flight schedule. Operators should confirm transfer routes shortly before departure and keep guests informed if access changes. Airports continue to operate while roads leading to them are partially blocked, causing disruptions. Staff shortages are also delaying baggage services at airports.
Bangkok’s drainage system is under sustained pressure from the rain’s volume and duration. Officials are working to remove water and clear obstructions from drainage routes. Their immediate task is to maintain access, support households in flooded areas and provide clear updates as conditions change.
Once the water recedes, the BMA will need to assess damage and the performance of drainage, canals and public warnings. For residents and businesses, the priority is a timely account of which routes have reopened, what assistance is available and how long disruption is likely to continue.
