GISTDA released updated flood situation images from the 'Check Water' app, stressing close attention to Sukhothai and nearby provinces where dark red high-risk flood zones have clearly expanded, covering multiple contiguous districts rather than being limited to the city center.
On 20 August 2026, the Facebook pageGISTDA, the Geo-Informatics and Space Technology Development Agency (Public Organization)posted a message stating the latest update from the 'Check Water' app, highlighting Sukhothai and nearby areas (based on satellite and geospatial data from GISTDA).
As of 20 August 2026 at 15:33, the "high risk" flood zones (dark red) have clearly expanded widely, not confined just to Sukhothai city, but forming a large red area covering multiple adjoining districts. Key areas to watch closely include:
Sukhothai Province – Dense dark red zones stretch from the north (Si Satchanalai and Sawankhalok districts), down through Sukhothai city, continuing to Kong Krailat district.
Phitsanulok Province – Most of the province, especially Phrom Phiram district and surrounding areas, is covered almost entirely by red zones.
Nearby Provinces – At the border area between southern Uttaradit and northern Phichit, red and yellow risk zones begin to appear intermixed.
This information is analyzed from GISTDA's satellite imagery, which is highly accurate and updated in real time, making it a reliable tool for monitoring the situation. The advice for residents in risk areas is not to panic but to prepare calmly and mindfully.
Check water levels around homes and evacuation routes, keep valuables in high places, prepare survival kits, and monitor water movement, danger alerts, and local conditions continuously through the 'Check Water' app.
