Disaster Declaration and Immediate Impact
On September 26, Governor Chadchart Sittipunt declared all 50 districts of Thailand’s capital a disaster-affected zone after three consecutive days of torrential rain. The Meteorological Department reported that nearly 300 mm (11.8 inches) of rain fell since Thursday afternoon, flooding streets to waist height and submerging major roads. The surge filled every canal, prompting an emergency advisory for residents living near canals to move possessions to higher ground. Authorities estimate that more than 84,000 people across 21 provinces are affected, with over 4,200 taking shelter in more than 200 temporary shelters set up throughout Bangkok.
Government and Military Response
- He urged residents to relocate cars to higher ground and advised bedridden patients dependent on life-saving equipment to consider temporary hospital stays.
- The Thai army deployed shelters and field kitchens, while the Bangkok Metropolitan Administration designated schools as temporary accommodation and asked residents to avoid non-essential travel.
- Bangkok’s public-transport authority offered free access to MRT “park-and-ride” carparks for vehicle storage until October 2.
Meteorological Outlook
Thailand’s Meteorological Department cautioned that the heavy rain would persist through Sunday, attributing the event to a strong low-pressure system strengthening monsoon conditions over the central region.

What’s Next
The weather agency expects rain to continue through Sunday, after which water levels should recede provided no further downpours occur. City officials plan to operate pumps and drainage systems aggressively, aiming for a return to normal conditions within two to three days. The free MRT park-and-ride service remains available until October 2, giving residents additional time to protect their vehicles while floodwaters withdraw.
