1. Expanding Singapore's X-Band Radar Network
Following the successful installation of three rainfall X-band radars, a forecast model, and an operational web interface in 2018, PUB awarded H2i a follow-up contract in February 2020 to double the system's operational reach.
- Radar Deployment: Three additional X-band radars (supplied by Furuno Singapore) will become operational over 12 months.
- Nationwide Coverage: Strategically positioned in areas with lower current coverage, the new additions bring the total to six radars, creating a dense, island-wide monitoring network.
2. AI and Deep Learning Innovation

To maximize data from the expanded radar network, H2i is upgrading the backend analytics framework:
- Machine Learning Enhancements: ML techniques refine raw observational radar data to improve overall accuracy.
- Predictive Nowcasting: Observational feeds power a nowcast model capable of tracking raincloud movement, growth, and decay up to 2 hours ahead.
- Deep Learning for Early Warning: Deep Learning algorithms enhance the model to predict heavy rainfall events 30 minutes before they occur, giving operational teams a vital head start.
3. Media Coverage and Public Recognition
The strategic importance of this flood management initiative has drawn widespread national attention. The project has been featured across major news outlets and official channels, including Channel NewsAsia (CNA), The Straits Times, The New Paper, and PUB's official Facebook page and website.
4. Conclusion & Key Takeaways
Conclusion
By expanding from three to six X-band radars and pairing the network with advanced Deep Learning algorithms, H2i and PUB are establishing a robust defense against extreme tropical weather. This data-driven upgrade turns short-term nowcasting into actionable, real-time flood management—helping Singapore stay one step ahead of localized downpours.
Key Takeaways
- Doubles Radar Density: Expands Singapore's rainfall radar network from 3 to 6 X-band radars for complete island coverage.
- 30-Minute Heavy Rain Warnings: Uses Deep Learning models to forecast severe rain events 30 minutes before impact.
- 2-Hour Nowcasting Window: Tracks cloud formation, growth, and movement to provide short-term meteorological intelligence.
- Industry & Media Recognition: Featured across major national platforms like CNA and The Straits Times as a flagship smart water management project.
