The government is expediting water management and lowering water levels in high-risk areas to prepare for new rainfall from 9–13 October, while accelerating flood recovery efforts to help people return to normal life quickly.
At 10:00 a.m. on 8 October 2026, at the Government News Center, Nareesamorn Building, Government House, Mr. Ekaphop Pianpiset, spokesperson of the Office of the Prime Minister, and Ms. Lalida Pertviwatana, deputy spokesperson, held a press conference at the Joint Information and Communication Center (JICC) on the flood situation, summarizing key points as follows.
Dr. Ekaphop Pianpiset, spokesperson of the Office of the Prime Minister, stated that the weather from 5–7 October 2026 proceeded as forecasted by the Meteorological Department, with rainfall amounts not exceeding expectations and water management continuing as planned.
Regarding the weather outlook, a new wave of rainfall is expected from 9 to 13 October 2026, especially between 10 and 12 October, with accumulated rainfall increasing in many areas, particularly the western region. From 13 October onward, increased rain is expected in the south. Residents in vulnerable areas are urged to closely monitor updates and warnings from relevant agencies.
As for the water situation in the Chao Phraya River, water levels are trending downward and remain manageable. Special watch areas include Prachinburi, Nakhon Nayok, and Chachoengsao provinces, where widespread flooding persists.
In Bangkok, most areas have returned to normal conditions, with residents able to travel on nearly all routes. In areas still flooded, officials are urgently draining water to allow people to resume daily life and restore homes as soon as possible.
The spokesperson added that rainfall over the past 2–3 days and water inflow above the Chao Phraya Dam remain within projections. Currently, water is released through the dam at 2,350 cubic meters per second, with upstream water level dropping to 16.03 meters. Relevant agencies will continuously manage water to prepare for the new rainfall while lowering downstream water levels to expedite aid, relief, and recovery efforts.
At Pasak Jolasid Dam, water management is being intensified to reduce excess storage to appropriate levels and prepare for new incoming water, coordinated with the canal system and Rama VI Dam. This is expected to lower water levels in Phra Nakhon Si Ayutthaya province by approximately 10–20 centimeters shortly.
In Pathum Thani, Nonthaburi, and Bangkok, water levels in the Chao Phraya River have not increased. Along with reduced water release rates at the dam, water levels are starting to fall and have not breached flood barriers.
In the western region, rain is expected in Kanchanaburi province on 10–11 October 2026. Srinakarin and Vajiralongkorn Dams have declining water levels and can still accommodate more water. Downstream in the Mae Klong River area, water levels have not overflowed banks and there is still capacity for water storage. However, as rainfall is forecast to increase, residents in Kanchanaburi, Ratchaburi, and Samut Songkhram provinces are urged to closely follow local warnings, especially those who have already moved belongings to higher ground, to remain vigilant and prepared for the new rainfall.
Meanwhile, Samut Songkhram province has installed 12 water pumps in Amphawa to accelerate water discharge to the sea. In Phetchaburi province, water management at Kaeng Krachan Dam involves reducing water levels to suitable limits to increase capacity for new rainfall, with measures ready to address potential rises downstream.
In the eastern region, which remains under special watch—especially Kabin Buri district in Prachinburi province—water levels are beginning to decrease. Inflow into Mueang Prachinburi district is also declining, albeit slowly, with widespread flooding still present.
In Nakhon Nayok province, continuous water management from Khun Dan Prakarn Chon Dam maintains water balance. Water from Prachinburi and Nakhon Nayok provinces converges at Ban Sang district in Prachinburi before flowing into the Bang Pakong River. Residents along the Bang Pakong River in Chachoengsao province are advised to closely monitor water levels, particularly the risk of water breaching flood embankments.
Ms. Wirongrong Suka, senior meteorologist at the Meteorological Department, noted that October 2026 forecasts indicate decreasing rain in upper Thailand, though thunderstorms may still occur locally. The south will continue experiencing heavy rain in some areas.
From 9 to 13 October 2026, a new rainfall wave is anticipated as the rainy season wanes, influenced by cold air mass from China covering upper Thailand, along with a monsoon trough passing over the upper south. The southwest monsoon continues over the Andaman Sea, southern region, and Gulf of Thailand, causing increased rain in different areas as follows.
- On 9 October 2026, rain will increase in the lower northeastern region, eastern region, and south, especially in Songkhla, Surat Thani, Phang Nga, Nakhon Si Thammarat, Ranong, and Yala provinces.
- On 10 October 2026, rain will increase in the lower northern region, lower northeastern region, central region including Bangkok and its vicinity, eastern region, and south, particularly in Nakhon Si Thammarat and Phang Nga provinces.
- On 11 October 2026, rain will increase in the lower northern region, central region including Bangkok and its vicinity, eastern region, and south, especially in Chumphon, Surat Thani, Ranong, Phatthalung, Songkhla, and Satun provinces.
- On 12 October 2026, the southern region will see increased rain, particularly in Surat Thani, Nakhon Si Thammarat, and Trang provinces.
- On 13 October 2026, rain will continue increasing in the south, especially in Ranong and Yala provinces.
The Meteorological Department advises residents in the mentioned areas to beware of dangers from heavy to very heavy rain and accumulated rainfall, which may cause flash floods, mountain floods, and waterlogging. People are urged to plan their activities and travel cautiously and to continuously follow weather forecasts and announcements from the Meteorological Department via their website or the 24-hour hotline 1182.
