# WeatherNext: AI model achieves breakthrough in forecasting cyclones

> Google DeepMind says its WeatherNext model has made a real jump in one of the hardest parts of forecasting, predicting where cyclones will go and how strong they will get. Its 3 day forecasts now match the accuracy older models managed at 2 days, a gain meteorologists say represents roughly a decade of normal progress compressed into one model. The proof was in last year's hurricane season, when WeatherNext helped the National Hurricane Center anticipate Hurricane Melissa's rapid intensification and its landfall in Jamaica. Rather than a single prediction, the system spins up 1,000 possible scenarios for each storm and can produce a 15 day forecast in under a minute on a TPU. What makes this notable beyond the accuracy is that DeepMind open sourced the WeatherNext 2 and Cyclones models on GitHub. That extra day of warning is the difference between an orderly evacuation and a scramble, and putting the tools in public hands means smaller weather agencies could use them too.
