Nearly one million people remain affected by flooding across 20 provinces and Bangkok, although water levels are falling and authorities are accelerating recovery and relief efforts, the Department of Disaster Prevention and Mitigation (DDPM) reported.
The department’s update as of 6am on October 27, 2026, recorded 978,112 people from 327,004 households affected. Flooding covered 60 districts, 387 subdistricts and 2,738 villages in the provinces, alongside two districts in eastern Bangkok.
DDPM director-general Nirat Pongsitthithaworn attributed the flooding to prolonged heavy to very heavy rainfall and water flowing downstream from northern Thailand into the Central Plains, where water had already accumulated.
While conditions are improving, the department is maintaining round-the-clock monitoring and deploying equipment to help affected communities, clean up flooded areas and assess damage ahead of financial assistance.
Bangkok accounted for 168,203 affected households across 14 subdistricts in Lat Krabang and Nong Chok. Four deaths were reported in the capital, where water levels were continuing to decline.
Among the nine affected Central-region provinces, Ayutthaya had the largest number of affected households at 52,188. Flooding covered 149 subdistricts and 988 villages across 11 districts, with three deaths reported.
The affected districts were Sena, Bang Ban, Phak Hai, Phra Nakhon Si Ayutthaya, Bang Pa-in, Bang Pahan, Lat Bua Luang, Uthai and Ban Phraek, together with the two districts whose names are both transliterated as Bang Sai.
The DDPM reported declining water levels across the affected Central-region areas.
Four eastern provinces remained affected, with water levels declining in most flooded areas.
Prachin Buri recorded 26 reported deaths, the highest figure among the areas listed in the update. Flooding continued in Si Maha Phot, Ban Sang and Si Mahosot districts, affecting 14 subdistricts, 93 villages and 9,805 households.
Nakhon Nayok had 23,835 affected households across 12 subdistricts and 117 villages in Ongkharak and Ban Na districts. Six deaths were reported.

Floodwaters were steadily receding in the three affected northern provinces:
In the South, conditions were also gradually returning towards normal, although flooding remained in four provinces:
Nirat instructed provincial DDPM offices and regional disaster prevention and mitigation centres to coordinate closely with local administrative organisations and other agencies as recovery work gathers pace.
In areas where floodwaters have receded, officials have been directed to mobilise machinery and equipment for clean-up and restoration work.
Teams will also accelerate surveys of damage to homes, public infrastructure and agricultural land. The findings will be used to compile detailed records of affected residents and arrange financial assistance under the Finance Ministry’s regulations and eligibility criteria.
The department aims to expedite assistance to ease hardship and help communities resume normal life, while continuing to monitor weather conditions and water levels around the clock.
People affected by flooding can report emergencies or request assistance through the DDPM’s 1784 hotline, available 24 hours a day.
