Bangkok — The Geo-Informatics and Space Technology Development Agency (GISTDA) reported data from its Check Nam application, which analyzes satellite imagery and geospatial information to monitor flood risks. The latest analysis showed a large, interconnected area classified as a very high-risk zone covering floodplain areas in Sukhothai, Phitsanulok and neighboring provinces, with the total area currently at risk of flooding exceeding 3,900 square kilometers.
Sukhothai has been widely affected, with large areas classified as high risk concentrated across the central and lower parts of the province, particularly in Sawankhalok, Si Samrong, Mueang Sukhothai and Kong Krailat districts, as well as parts of Si Satchanalai district in the north. In Phitsanulok, extensive high-risk areas were detected in the central and western parts of the province, with floodwater connected to the flow from Sukhothai affecting major areas including Phrom Phiram, Bang Rakam and Mueang Phitsanulok districts, as well as parts of Wat Bot district.
Nearby areas and neighboring provinces including Uttaradit, Phichit and Kamphaeng Phet have also recorded both very high-risk and low-risk zones. GISTDA said the assessment was based on high-accuracy satellite imagery updated in real time, allowing authorities to assess the direction and expansion of floodwater accurately and helping relevant agencies and residents plan monitoring and response measures more effectively. GISTDA advised residents in affected and nearby areas to closely monitor the situation around the clock.
