IES & HYDS Complete Early Warning System Project in Tonga
In December 2025, IES and HYDS successfully completed the Site Acceptance Tests (SAT) of their fully Integrated Forecasting Platform (IFP) and Early Warning System for the Tonga Meteorological Service (TMS). Built on IES's Met-WebGIS platform and Argos from HYDS, the system represents a major advancement in Tonga's national forecasting and warning capabilities.
The integrated platform provides forecasters with a single, intuitive environment to seamlessly access, visualize, and analyze diverse meteorological data sources — including in-situ observations, remotely sensed data and Numerical Weather Prediction (NWP) model outputs. It enables the rapid dissemination of high-quality forecasts and warnings to government authorities, media, aviation, marine users, and the general public.
Beyond weather services, the platform also strengthens national resilience by supporting the rapid dissemination of tsunami warnings and volcanic information, helping protect lives, infrastructure, and livelihoods.
