A Flood Early Warning System (FEWS) is a structured framework designed to detect potential flood threats and inform communities in advance. It integrates meteorological data, hydrological models, and real-time monitoring of river levels and rainfall.

By analyzing weather forecasts, satellite imagery, and historical data, FEWS can predict flooding events accurately. Once a risk is identified, alerts are sent to local authorities and communities, enabling them to take precautionary measures, such as evacuation or securing property.

The effectiveness of FEWS relies on timely and accurate information dissemination, ensuring that people have enough time to respond. Ultimately, this system plays a crucial role in minimizing the impact of floods, protecting lives, and reducing economic losses.
