WING Act of 2025

This bill tells the National Weather Service to set up a research and testing program to keep weather radar accurate when objects are in the way, like wind turbines. The program will work with businesses, universities, and all levels of government to find, test, and develop fixes. It looks at smarter signal processing, short-term forecasts to fill in bad radar spots, and ways to use dual‑polarization radar to reduce wind farm effects. It also prioritizes tools like phased‑array radar, swapping in commercial radar data, using private weather‑tower data, showing wind farm boundaries on local forecast screens, adding rain gauges, and other methods to reduce “beam blockage” and “ghost echoes” in radar data.

Reports to Congress are due two years after the law takes effect and then every year after that, with a final recommendation within five years. The program ends by September 30, 2030, or one year after the final recommendation—whichever comes first.

Key points

• Who is affected: National Weather Service; weather researchers and partners; communities near wind farms and other radar obstructions.
• What changes: Creates a program to test and develop tech solutions to keep radar data reliable, including algorithms, new radar systems, private data sources, and added sensors like rain gauges.
• When: First report due two years after enactment; annual reports after that; program ends by 2030 or sooner depending on the final recommendation.
