GISTDA Satellite Images Map Thailand's Flood Risk

Last Updated on September 26, 2026 by Jeff Tomas

BANGKOK – Thailand is currently facing a serious threat from rising floodwaters following several weeks of continuous heavy rain. On September 25, 2026, the Geo-Informatics and Space Technology Development Agency (GISTDA) released startling new satellite images.

These detailed maps show widespread high-risk flood zones stretching across multiple regions of the entire country. Government officials are now urging all residents living in these critical red zones to monitor local weather conditions very closely.

The latest satellite data reveals a worrying expansion of severely flooded areas in the central and lower northern regions. Continued heavy downpours have pushed rivers past their natural limits, sending water spilling into nearby low-lying communities.

Down in the lower northeast, massive stretches of vital agricultural land and riverbank homes are already sitting underwater. Because of this growing crisis, disaster relief teams are working around the clock to assist the affected families.

Key Takeaways

Satellite imagery from GISTDA shows expanding high-risk flood zones marked in red across Thailand.
Central, lower northern, and lower northeastern provinces are currently facing the most severe water threats.
Residents in these dangerous areas should prepare to move their belongings to higher ground immediately.

Expanding Red Zones and Affected Areas

The agency’s satellite analysis highlights a dense concentration of red zones that demand immediate public attention. In the central and lower northern regions, provinces like Nakhon Sawan, Lop Buri, and Suphan Buri are highly vulnerable.

The danger zone even stretches southward to impact communities in Pathum Thani, Nonthaburi, and parts of Bangkok. Meanwhile, northeastern provinces such as Surin, Buriram, and Roi Et are battling wide-scale water accumulation along their major river basins.

The massive flooding is also taking a heavy toll on the local economy and the nation’s food supply. Thousands of acres of highly fertile farmland are currently trapped under deep, stagnant floodwater across the country.

For many rural farmers, this unexpected natural disaster severely threatens their primary source of income for the entire year. Local leaders are desperately hoping the floodwaters will recede quickly to prevent permanent damage to these crucial crops.

To help people stay completely safe, GISTDA highly encourages the public to use their modern mobile tools. The agency’s “Check Water” app delivers real-time flood updates directly to smartphones across the entire nation. This simple technology easily empowers everyday citizens to track changing water levels in their specific local neighborhoods. By having this crucial information on hand, families can make quick, informed decisions about exactly when to evacuate.

Space Technology Guides Flood Relief Efforts

Using advanced space technology is constantly proving essential for national water management and rapid disaster response efforts. The nationwide map clearly displays yellow warning points and red danger points stretching from the north down to the south.

This daily satellite processing gives government agencies a perfectly clear picture of exactly where the dangerous water is flowing. As a result, the Department of Disaster Prevention and Mitigation can easily plan smarter drainage routes toward the sea.

This high-tech mapping approach also allows rescue teams to target their emergency assistance much more effectively. Instead of simply guessing where help is needed, authorities can confidently send boats and supplies directly to the hardest-hit communities.

Furthermore, local government officials are strongly advising vulnerable residents to prepare their homes for the absolute worst-case scenario. People should completely avoid traveling on flooded roads, quickly relocate their livestock, and secure their valuables on much higher ground.
