Satellite data reveals high flood-risk areas across Thailand
GISTDA satellite images on September 25 show high flood-risk areas in several provinces after prolonged heavy rainfall across Thailand.
- Satellite data from Thailand's space agency, GISTDA, has identified extensive areas at high risk of flooding across the nation following persistent heavy rainfall.
- The Central and lower Northern regions are significantly affected, with high-risk zones detected in provinces such as Nakhon Sawan and Lop Buri, extending towards Bangkok.
- Widespread water accumulation and high-risk clusters have also been revealed in the lower Northeast, particularly along river basins in provinces including Surin and Si Sa Ket.
- The information is being used by authorities to manage water flow, plan drainage, and coordinate assistance for residents in the designated danger zones.
The Geo-Informatics and Space Technology Development Agency (GISTDA) has released satellite images showing areas at high risk of flooding following continued heavy rainfall across Thailand.
The latest data, collected on Friday (September 25) at 8.38am, uses satellite technology and geospatial information from GISTDA’s “Check Nam” application to monitor water situations nationwide in real time.
Central and lower northern regions face expanding flood risks
Satellite analysis showed large areas with high flood risk alerts, marked in red, across several provinces in the Central and lower Northern regions.
The affected areas include Nakhon Sawan, Phichit, Phetchabun, Lop Buri, Saraburi and Suphan Buri, extending southwards to Pathum Thani, Nonthaburi and parts of Bangkok.
The data also identified warning points and flooded road sections scattered across several major routes.
Lower Northeast hit by widespread water accumulation
In the lower Northeast, satellite images detected dense clusters of high-risk areas along river basins, covering Surin, Si Sa Ket, Buri Ram and Roi Et.
Floodwaters have spread into low-lying areas near rivers and agricultural zones, affecting local communities and farmland.
Flood alerts spread across several regions
The nationwide overview shows warning points marked in yellow and danger zones marked in red across the North, Northeast, Central region and South.
GISTDA’s satellite-based monitoring provides key information for water management agencies, including the Department of Disaster Prevention and Mitigation (DDPM) and local authorities, to assess water flows, plan drainage routes and coordinate assistance for affected residents.
Public urged to monitor updates and prepare
GISTDA advised people living in red-zone areas and low-lying locations near waterways to closely follow weather forecasts and water-level updates.
Residents were also encouraged to avoid travelling through flooded roads, move belongings to higher ground, and relocate livestock and vehicles to safer areas when necessary.
