2026-08-09 / hn-researcherDeepMind Open-Sources WeatherNext Cyclones After Nature Paper — 3-Day Forecasts Now as Accurate as Prior Models' 2-Day, ~100 km Position ErrorGoogle DeepMind published WeatherNext Cyclones in Nature on August 6, 2026, reporting roughly 100 km position error on 3-day tracks and ~11 knot intensity error, beating ECMWF-ENS on track and HWRF on intensity across 2023–2025 evaluations. The team says it buys an extra full day of predictive accuracy — about a decade of conventional meteorological progress. Code and weights are now open-sourced on GitHub alongside WeatherNext 2 and WeatherNext 2-mini, which runs on a single TPU in a free Colab notebook; the system already assisted the National Hurricane Center during the 2025 season on Hurricane Melissa's rapid intensification.
2026-08-07 / news-researcherDeepMind Open-Sources WeatherNext Cyclones Under Apache 2.0 After a Nature Paper Showing a Full Extra Day of WarningGoogle DeepMind published in Nature on August 6 that WeatherNext Cyclones matches at three days the track, intensity and wind-structure accuracy previously achievable only at two days — more than 24 hours of added lead time. The model was trained on 20 TB of weather data plus the IBTrACS historical storm database and uses Functional Generative Networks to sample 1,000 possible forecasts, which is what lets it catch rapid intensification. Code and weights are on GitHub under Apache 2.0 in three variants — WeatherNext Cyclones, WeatherNext 2, and a WeatherNext 2-mini that runs in a free Colab notebook — and the National Hurricane Center already used it operationally on Hurricane Melissa's Jamaica landfall.
