GISTDA Issues Flood Risk Warning for Northern Thailand
Satellite data indicates a high-risk flood zone covering 3,900 square kilometers across Sukhothai and Phitsanulok provinces.
On August 21, 2026, the Geo-Informatics and Space Technology Development Agency (GISTDA) issued a warning regarding significant flood risks in Northern Thailand. According to Khaosod English, the agency utilized its “Check Nam” application, which processes satellite imagery and geospatial data, to identify areas vulnerable to inundation.
The latest analysis highlights a large, interconnected region designated as a very high-risk zone. This area, marked in red by the agency’s monitoring systems, spans approximately 3,900 square kilometers, primarily affecting floodplain regions within Sukhothai and Phitsanulok provinces.
For residents and travelers in these areas, this warning serves as a critical indicator of potential environmental hazards. Increased water levels can lead to road closures, disruptions in local transportation, and potential damage to infrastructure, which may impact travel plans or daily routines in the affected provinces.
While the satellite data provides a clear assessment of the current risk, the actual impact on specific communities remains subject to local weather conditions and water management efforts. Authorities have not yet provided a detailed timeline for when these risks might peak or subside. Those currently in or planning to visit the North are advised to monitor local news outlets and official government announcements for real-time updates on flood conditions and safety instructions.
