On the morning of 25 Sep 2026 GMT+7, GISTDA released satellite images revealing high flood risk areas in multiple provinces after accumulated heavy rainfall. Residents in red zones and low-lying areas near waterways were urged to monitor closely.
On 25 Sep 2026 GMT+7, it was reported that the fan page ofGISTDA, the Geo-Informatics and Space Technology Development Agency (Public Organization),released satellite images this morning (25 Sep 2026 GMT+7), warning of high flood risk areas in several provinces after continuous heavy rain.
The Geo-Informatics and Space Technology Development Agency (Public Organization), or GISTDA, uses satellite technology and geospatial data to monitor and track water situations across Thailand in real time through the “Check Water” application. The latest data as of 25 Sep 2026 GMT+7 at 08:38 shows areas affected and at risk from ongoing heavy rainfall.
Flooding in central and lower northern regions: Satellite image analysis reveals a concerning expansion of high-risk areas (red zones) covering many provinces including Nakhon Sawan, Phichit, Phetchabun, Lopburi, Saraburi, Suphanburi, extending down to Pathum Thani, Nonthaburi, and parts of Bangkok. Alerts and flooded road spots are scattered along key routes.
Lower northeastern region inundated along river basins: Satellite images show dense high-risk areas (red zones) in lower northeastern provinces including Surin, Sisaket, Buriram, and Roi Et. Floodwaters have submerged low-lying riverbank and agricultural areas extensively, inevitably impacting residents' livelihoods.
Nationwide overview and current situation linkage: Across the country, warning points (yellow symbols) and danger points (red symbols) are scattered from the north, northeast, central, down to the south. This morning's satellite data processing is crucial for water management agencies, the Department of Disaster Prevention and Mitigation, and local authorities to assess water flow direction, plan drainage to the sea, and provide timely, targeted assistance to affected populations.
Guidelines and warnings for the public: GISTDA emphasizes that residents living in red zones (high risk) and low-lying areas near waterways should closely monitor weather and water level updates, exercise caution when traveling through flooded roads, prepare to move belongings to higher ground, and relocate livestock and vehicles to safe areas.
The “Check Water” application is available for download on both iOS and Android platforms.
