The government has mobilized the Department of Disaster Prevention and Mitigation (DDPM) to manage flooding in 12 provinces by setting up a War Room, sending machinery and Emergency Response Teams (ERT) to speed up water drainage, and maintaining 24-hour surveillance of high-risk areas.
On 25 September 2026, Ms. Lalida Pertwiwatana, Deputy Spokesperson of the Prime Minister's Office, disclosed that due to heavy to very heavy rainfall in multiple areas combined with water volume from the northern region flowing into the central region, Mr. Jeset Thaiset, Deputy Minister of Interior (MoI 3), has instructed the Department of Disaster Prevention and Mitigation (DDPM) to mobilize personnel and disaster machinery to affected areas to accelerate water drainage and provide comprehensive aid to the public while closely monitoring vulnerable areas.
Ms. Lalida stated that data from the Disaster Prevention and Mitigation Operations Center (DDPM Operations Center) as of 25 September 2026 at 06:00 shows flooding in 12 provinces: Phetchabun, Nakhon Sawan, Uthai Thani, Sing Buri, Suphanburi, Saraburi, Phra Nakhon Si Ayutthaya, Prachin Buri, Chachoengsao, Sa Kaeo, Trat, and Surin. This affects 38 districts, 143 subdistricts, and 596 villages, impacting 11,796 households totaling 37,036 people. The DDPM has deployed personnel and machinery to assist and alleviate residents' hardships in these areas.
Regarding the situation trends, water levels are decreasing in Phetchabun, Uthai Thani, Saraburi, Trat, and Surin provinces. Meanwhile, water levels remain stable in Nakhon Sawan, Sing Buri, Phra Nakhon Si Ayutthaya, and Prachin Buri. However, water levels are rising in Suphanburi, Chachoengsao, and Sa Kaeo. The DDPM and local agencies are closely monitoring the situation and preparing to respond promptly as needed.
Mr. Jeset has instructed the DDPM to establish a systematic flood response protocol. Disaster Prevention and Mitigation Centers in the Chao Phraya basin and lowland areas are directed to set up command and monitoring centers, or War Rooms, to oversee water situation assessments and manage personnel and machinery deployment appropriate to each area's conditions.
In the central region, including the Chao Phraya and Tha Chin river basins, responsibility zones have been divided among DDPM regional centers to enable rapid provincial support: DDPM Region 1 in Pathum Thani covers Pathum Thani, Nonthaburi, Samut Prakan, and Saraburi; DDPM Region 2 in Suphanburi covers Suphanburi, Kanchanaburi, Nakhon Pathom, and Ratchaburi; and DDPM Region 16 in Chai Nat covers Chai Nat, Lopburi, Sing Buri, and Ang Thong. Emergency Response Teams (ERT) and disaster machinery are strategically positioned in risk areas and at key floodgates to aid water drainage and preemptive water release.
DDPM Region 2 in Suphanburi has dispatched disaster machinery to support Kanchanaburi, Phra Nakhon Si Ayutthaya, Suphanburi, and Ang Thong provinces, including flat-bottom boats with engines, water pumps, rescue transport vehicles, and mobile kitchens. Other DDPM regions have prepared rescue boats—including flat-bottom, aluminum, and polyethylene types—and various water pumps, ready to support provinces as necessary.
Ms. Lalida added that the DDPM's mission encompasses accelerating water drainage, ensuring safety, evacuating residents and vulnerable groups, transporting goods, and supporting livelihoods by producing clean drinking water, installing lighting, and operating mobile kitchens. If regional disaster machinery proves insufficient, Mr. Jeset has instructed immediate coordination with central DDPM to deploy additional personnel and equipment promptly to avoid any interruption in assistance to affected populations.
Special monitoring is required for areas identified by the National Disaster Warning Center, which has analyzed weather patterns and predicts close observation from 25–28 September 2026. In the central region, provinces such as Chai Nat, Sing Buri, Ang Thong, Lopburi, Saraburi, Phra Nakhon Si Ayutthaya, Nakhon Nayok, Prachin Buri, Sa Kaeo, Chanthaburi, and Trat are under surveillance, along with Kanchanaburi, Phetchaburi, and Prachuap Khiri Khan in the following period. Areas experiencing prolonged rainfall, like Chanthaburi and Trat, face landslide risks. In the north, provinces including Tak, Uthai Thani, Kamphaeng Phet, Phitsanulok, and Nakhon Sawan are also monitored.
“Mr. Jeset Thaiset, Deputy Minister of Interior, has emphasized that regional DDPM centers prepare disaster machinery to be ready for immediate deployment upon request, coordinate water management closely with provinces, and assign personnel for 24-hour monitoring and emergency response to support provincial response plans and assist residents swiftly—especially in areas with rising water levels and heavy rainfall risk,” Ms. Lalida said.
Ms. Lalida stressed that the government is continuously monitoring the situation, prioritizing rapid water drainage where feasible, pre-positioning machinery and personnel, and giving special care to the elderly, patients, disabled persons, and vulnerable groups to ensure assistance is fast, sustained, and comprehensive. She urged residents in risk zones to closely follow announcements and advice from local government agencies.
