Hong Kong scientists say this AI can spot storms 4 hours early — why forecasters are watching

Hong Kong scientists say their new AI-based DDMS system can predict thunderstorms and heavy rain up to four hours in advance, extending warning times. The model updates every 15 minutes and improved forecast accuracy by over 15% in tests. China’s Meteorological Administration and the Hong Kong Observatory plan to integrate the system into official forecasts.

Nvidia’s open-source Earth-2 AI weather models drop as a U.S. winter storm tests forecasts

Nvidia unveiled new open AI weather models at a Houston meteorology conference, including Earth-2 Medium Range, which it says outperformed Google DeepMind’s GenCast on over 70 variables. The models run on GPUs for faster, more frequent forecasts and allow users to operate and customize them on their own hardware. Nvidia is releasing the models and tools as open source via Hugging Face.

Northern Lights Tonight? NOAA says aurora could reach New York as solar storm lingers

NOAA extended geomagnetic storm warnings Wednesday after a rapid coronal mass ejection triggered by an X-class solar flare caused severe conditions. Auroras may be visible as far south as Alabama and northern California, with rare sightings in northern Italy and the UK. The storm reached G4 and S4 levels, threatening satellites, navigation, and polar flights. Forecasters say such intensity hasn’t been seen in over 20 years.

Northern Lights Could Reach Farther South Tonight After NOAA Flags Severe Solar Storm

Severe G4 geomagnetic storm levels were recorded early Tuesday after a coronal mass ejection struck Earth, NOAA said. A rare severe solar radiation storm was also underway, raising risks for polar flights and satellites. Agencies in the U.K. and Australia reported similar conditions and warned of possible G5 intervals. NOAA notified airlines, NASA, and grid operators as the situation developed.

‘Strange’ 2025 Hurricane Season Ends With No U.S. Landfalls as NOAA Debuts New Space‑Weather Sentinel

No tropical cyclones are active in the Atlantic with five days left in the 2025 hurricane season, the National Hurricane Center said. For the first time in a decade, no hurricane made U.S. landfall, though Category 5 Hurricane Melissa caused $50 billion in damage in the Caribbean. Meanwhile, NOAA’s new SWFO-L1 satellite began streaming real-time space-weather data for early solar storm warnings.
