## Summary

Google DeepMind’s WeatherNext Cyclones model won the 2026 Gizmodo Science Fair for predicting tropical cyclone tracks and intensity with unprecedented accuracy. During the 2025 Atlantic hurricane season, it gave forecasters an extra day of warning for Hurricane Melissa, reaching 80% confidence five days ahead and nearly 100% three days before landfall. A study in *Nature* confirmed the model’s average lead time improvement over historical data from 2023–2025, matching progress seen in traditional forecasting over a decade.

Developed by DeepMind researchers like Tom Andersson and Ferran Alet, the model addresses long-standing challenges: balancing track and intensity predictions, and handling rare but extreme storms. Unlike physical models, WeatherNext Cyclones runs on standard hardware and is open-sourced via GitHub. The team aims to expand global partnerships beyond the U.S. and Caribbean, citing climate-driven increases in storm intensity as a priority. The model’s ability to generate 1,000 scenarios also helps mitigate the ‘gray swan’ problem—underrepresented extreme events—critical for vulnerable regions.

## Key points

- WeatherNext Cyclones predicts hurricane tracks and intensity with 80% confidence five days ahead, per a 2026 *Nature* study
- Model provides an extra day of warning on average, matching a decade’s progress in traditional forecasting
- Open-sourced and accessible via GitHub, requiring no supercomputer, for global forecasters

## Why it matters

Five extra days of warning for hurricanes could save lives and reduce damage in a warming climate, where storms are intensifying faster. The model’s open-source design and global scalability address gaps in under-resourced regions.
