Satellite Images Show Severe Flooding Risk Across Multiple Thai Provinces
Satellite data shows severe flooding across central Thailand including Bangkok and the lower northeast, with high-risk zones identified in nine provinces as heavy rainfall continues to threaten agricultural areas and residents' livelihoods.
The Geo-Informatics and Space Technology Development Agency (GISTDA) used satellite technology and geospatial data to monitor water conditions across Thailand in real time through the Check Water application. Data recorded at 08:38 a.m. on September 25, 2026, identified areas affected by and at risk from continuous heavy rainfall. Satellite analysis of the central and lower northern regions revealed high-risk zones (marked in red) expanding significantly across Nakhon Sawan, Phichit, Phetchabun, Lopburi, Saraburi, Suphan Buri, Pathum Thani, Nonthaburi, and parts of Bangkok. Hazard warnings and road flooding were also detected at multiple key routes. In the lower northeast, satellite imagery showed dense, high-risk areas (red zones) covering Surin, Sisaket, Buriram, and Roi Et provinces, with floodwaters inundating low-lying areas along river basins and agricultural zones, inevitably affecting residents' livelihoods. Nationwide satellite data showed warning points (yellow symbols) and danger zones (red symbols) scattered from the northern region through the northeast, central, and southern regions. GISTDA emphasized that the morning satellite data processing was critical for water management agencies, the Department of Disaster Prevention and Mitigation, and local authorities to assess water flow direction, plan drainage to sea, and provide timely assistance to affected communities. GISTDA urged residents in red-alert areas and low-lying zones near waterways to closely monitor weather and water-level updates, exercise caution when traveling through flooded road areas, move valuables to higher ground, and relocate livestock and vehicles to safe zones.
