Bangkok Declares All 50 Districts Flood Disaster Areas
Nearly 300 mm of rain in about two days has flooded roads, overwhelmed canals and forced evacuations across Thailand's capital, while more than 84,000 people have been affected by flooding nationwide.
Authorities in Bangkok have declared all 50 districts of Thailand's capital as flood-disaster areas after days of intense rainfall inundated roads, pushed canals towards critical levels and forced some residents to evacuate.
The Bangkok Metropolitan Administration expanded the declaration across the entire city on September 26 after initially designating three districts as disaster areas.
Nearly 300 millimetres of rain had fallen across Bangkok since Thursday afternoon, according to Bangkok Governor Chadchart Sittipunt, with eastern parts of the city among the areas facing the most severe conditions.
BANGKOK FLOOD SNAPSHOT
50 districts — All Bangkok districts declared disaster areas
Nearly 300 mm — Rain recorded since Thursday afternoon
84,000+ people — Affected across Thailand
21 provinces — Reporting flood impacts
Major roads across Bangkok were submerged as persistent rainfall overwhelmed drainage systems and filled canals. Images from the city showed vehicles stranded in deep water while residents moved through flooded streets.
Authorities deployed pumping equipment across affected areas, with the Bangkok Metropolitan Administration reporting a combined pumping capacity of around 1,200 cubic metres of water per second.
Officials said water levels had begun stabilising in some areas and could improve relatively quickly if additional heavy rainfall did not occur.
However, canal-side and low-lying communities remained particularly vulnerable because already elevated water levels reduced the city's capacity to absorb further rainfall.
The governor urged residents living near canals to closely monitor conditions and move important belongings to higher ground.
EMERGENCY RESPONSE
1 million sandbags — Prepared for distribution
Temporary shelters — Opened in schools
Pumping stations — Operating at high capacity
Cell-broadcast alerts — Sent to residents in vulnerable areas
Authorities also advised bedridden residents who rely on life-supporting medical equipment to consider temporarily moving to hospitals while flood risks remained elevated.
Temporary shelters were established in schools, while some government facilities were opened to provide safer parking locations for vehicles.
The flooding has extended well beyond Bangkok.
As of Saturday, more than 84,000 people across 21 Thai provinces had been affected, with central Thailand among the regions facing significant flooding.
Thailand's Meteorological Department warned that heavy to very heavy rainfall could continue through September 27, raising the possibility of further flash flooding, waterlogging and overflowing waterways.
The weather conditions have been linked to a low-pressure system over central Thailand combined with strengthening southwest monsoon conditions.
Transport has also been disrupted.
Passengers travelling to Suvarnabhumi and Don Mueang airports were advised to allow additional travel time because flooded roads and poor weather could complicate access and potentially affect flight schedules.
Conditions at sea have also deteriorated. Weather authorities warned of rough conditions in parts of the Gulf of Thailand and Andaman Sea, with waves potentially reaching two to three metres and becoming higher during thunderstorms.
Small boats in affected areas were advised to remain ashore.
Bangkok authorities continue to operate pumping stations and monitor canal and rainfall levels as emergency teams assist communities in flooded areas.
The declaration of all 50 districts as disaster areas allows the Bangkok Metropolitan Administration and other government agencies to accelerate and coordinate emergency assistance across the capital as authorities respond to one of the city's most significant recent rainfall events.
