Northern Thailand Flood Risk Expands to Sukhothai and Phitsanulok
Satellite data indicates a significant increase in high-risk flood zones across northern and northeastern Thailand as of August 20, 2026.
According to a report from the Thai Enquirer on August 21, 2026, the ongoing flooding crisis in northern Thailand has intensified and spread into new provinces. Data retrieved on August 20, 2026, from the Geo-Informatics and Space Technology Development Agency (GISTDA) via the 'Check Nam' application shows a marked expansion of areas classified as having a 'very high' flood risk.
The satellite imagery highlights that these red-coded zones now encompass parts of Sukhothai and Phitsanulok. This development is significant for residents and travelers in these regions, as it suggests a heightened potential for infrastructure disruption and travel delays in the affected areas.
While the GISTDA data provides a clear indication of the geographical spread of the risk, the specific impact on local transport routes and the duration of these flood conditions remain to be confirmed. Those currently in or planning to visit the northern and northeastern provinces are advised to monitor local updates and utilize official resources like the 'Check Nam' application for real-time information. Authorities have not yet provided a timeline for when these flood-risk levels might subside, and the situation remains fluid as the water continues to move through the region.
