Bangkok has been declared a disaster zone after more than 24 hours of heavy rain caused widespread flooding.
More than 90 roads were affected and several canals reached critical levels. Authorities are working to drain hundreds of millions of cubic metres of water and estimate clearance could take two to three days if no further significant rain falls. Temporary shelters have opened and travellers are advised to check conditions carefully.

A flood emergency disaster was declared across all 50 districts of Bangkok, Thailand. Torrential monsoon downpours dumped nearly 300 mm (12 inches) of rain in less than 48 hours, completely overwhelming the capital’s municipal drainage systems and canals. Bangkok Governor Chadchart Sittipunt enacted the emergency designation on Saturday, 26 September 2026, warning that the crisis posed an active risk to life and property.
Key thoroughfares including Phetchaburi Road, Sukhumvit feeder streets, and low-lying eastern districts like Nong Chok and Suan Luang were submerged under waist-deep water, leaving roads impassable and vehicles stranded. According to the Bangkok Metropolitan Administration (BMA), roughly 52,000 households were affected and nearly 4,900 people were evacuated to emergency shelters set up in municipal schools. All Bangkok municipal schools remained closed on Monday. Government employees were urged to work from home to minimise traffic, while residents flooded local stores to stock up on food, ready-to-eat meals, and fresh water.
The disaster designation allowed district chiefs and civil protection units to immediately bypass typical red tape to deploy emergency funding, requisition heavy industrial pumps, and coordinate with the army to distribute relief. The BMA issued safety guidelines advising residents living near the city’s khlongs to move electrical appliances, valuables, and vehicles to upper floors or higher ground immediately, as the waterways burst their banks. The public was strongly advised to avoid all unnecessary travel. Drivers looking to preserve their vehicles were permitted to park on high-clearance bridges. Although rains temporarily subsided on Sunday, the Thai Meteorological Department extended heavy to very heavy rainfall warnings through 27 September 2026 due to a strengthening southwest monsoon.
