A compilation of sources to check water levels, rainfall, and road conditions with mobile alerts, plus tools to assess flood risk by your location.
Heavy continuous rainfall for several days has caused flooding in many areas. Meanwhile, the National Water Resources Office (NWRO) issued its sixth announcement to monitor ponding, flash floods, and river overflows in 30 provinces including Bangkok from 26 to 30 September.
With rapidly changing conditions, knowing where to get information helps you make timely decisions about travel and preparation. Below are government channels and tools to track the situation promptly.
ThaiWater, the National Water Information Repository by the Hydro-Informatic Institute (Public Organization), consolidates data on rainfall, river water levels compared to critical thresholds, reservoir volumes and discharge, plus storm tracks on a single map. It helps estimate when water from upstream areas will reach downstream locations. The application features "My Area" to receive alerts for selected locations.

The CheckWater application from the Geo-Informatics and Space Technology Development Agency (Public Organization), or GISTDA, uses satellite data combined with water level stations, weather stations, and CCTV cameras. By marking your location, you can see the risk level there. GISTDA states the system analyzes at a 1-square-kilometer resolution and predicts flood risk hourly. It assesses whether water will overflow riverbanks within the next 3 hours using station data and includes 18 years of historical flood records to check if your home or usual routes have flooded before. Available for iOS and Android by searching "CheckWater" or view provincial flood summaries at disaster.gistda.or.th on a computer.
