The government has raised flood monitoring to 24 hours daily from 25 to 27 Sept., ordering care for vulnerable groups and stockpiling water, electricity, oxygen, medicine, and blood supplies to last at least 72 hours.
On 25 September 2026, Ms. Ploytale Lakshamisangchan, Deputy Spokesperson for the Prime Minister's Office, stated that due to heavy to very heavy continuous rainfall in many parts of Thailand, there is a risk of flash floods, forest runoff, and riverbank overflow. The government is concerned for the people and has instructed all agencies to collaborate closely in monitoring and tracking the situation, issuing evacuation warnings for residents in risky areas, and providing comprehensive, ongoing assistance, especially to vulnerable groups such as the elderly, disabled, bedridden patients, dialysis patients, those requiring oxygen, and patients needing continuous medication, as follows.
1. All health regions and provinces in risk areas are to elevate monitoring to 24 hours daily at least until 27 Sept. 2026, especially in the Chao Phraya basin, central-western, and eastern regions where water levels are still rising. Health regions 3, 4, and 6 must open Emergency Public Health Operation Centers (EOC) at the regional level to closely monitor the situation.
2. Health regions 3 and 4, covering the Chao Phraya basin—particularly Phra Nakhon Si Ayutthaya, Pathum Thani, Rangsit—and downstream areas must closely track water levels, community risk points, healthcare facilities, and EMS/Referral routes.
3. Health region 6 must monitor the situation in Chanthaburi and Sa Kaeo provinces, including communities, hospitals, and the EMS system, due to ongoing high rainfall in several locations.
4. All hospitals in risk areas must prepare critical systems for at least 72 hours, including electricity, backup generators, fuel, clean water, oxygen, medicines, medical supplies, blood, food, IT/communication, personnel, and backup transfer routes. Continuous service should be maintained as safely possible. Electrical and water systems around buildings, entrances and exits, and ambulance routes must be reassessed. Any threats to services must be reported immediately.
5. Accelerate care for vulnerable groups and patients requiring ongoing treatment, including the elderly, disabled, bedridden patients, dialysis patients, oxygen users, and those needing continuous medication. Review registries and access/evacuation plans in advance.
6. In areas with shelters and evacuation zones, public health teams must promptly assess availability of clean water, drinking water, food, communicable diseases, regular medications, mental health, and vulnerable groups.
7. Every province must inspect and report any EMS/Referral routes that are impassable or at risk of closure, and designate alternative routes, transfer points, vehicle/boat support, and destination hospitals before incidents occur.
8. Immediate reporting is required when critical events occur, such as floodwater entering hospital areas, failures in electricity, water, or oxygen systems, cut EMS routes, patient evacuations or relocations, deaths or missing persons, or service suspensions. There is no need to wait for regular reporting cycles. If no emergencies occur, summaries should be submitted as scheduled.
"The government emphasizes that all relevant agencies remain prepared 24 hours a day for water management, drainage, and machinery deployment in risk areas. Officials are urged to assist and care for vulnerable groups on the ground. Residents in risk areas should closely follow official announcements, maintain hygiene, and follow safety recommendations," Ms. Ploytale said.
