DeepMind’s hurricane breakthrough has surprised weather scientists

Open source WeatherNext model can make accurate predictions with lower-resolution weather data.

The short version

• In October 2025, a storm brewed over the Caribbean Sea.
• Weather models differed on its trajectory.
• Would it remain weak and end up in Haiti, or would it intensify and head to Jamaica?

What happened

Artificial intelligence model WeatherNext, developed by Google’s DeepMind and Google Research, went with the latter. Five days before landfall, it predicted with 80 percent confidence that the storm system would hit Jamaica as a Category 5 hurricane.

Why it matters

Hurricane Melissa was catastrophic, causing flooding and landslides across Jamaica.
