Bangkok’s governor has declared the Thai capital a disaster-affected zone after nearly 300 millimetres of rain fell within 48 hours and caused widespread flooding.

Major roads were submerged, vehicles were left partly underwater and residents in several districts had to move through waist-high floodwater.

Governor Chadchart Sittipunt said the emergency threatened lives and property, with communities close to canals facing the most severe conditions.

The Thai army began establishing shelters and field kitchens, while city authorities opened schools as temporary accommodation for displaced residents.

Officials advised people near canals to move possessions to higher ground and asked the wider public to avoid unnecessary travel during continuing thunderstorms.

Suvarnabhumi Airport remained operational, but travellers were advised to allow an additional two to three hours because of difficult road conditions.

The crisis follows deadly flooding in southern Thailand last year and highlights the growing vulnerability of dense Asian cities to extreme rainfall.
