Weather Act Reauthorization Act of 2025

Updates and reauthorizes federal weather, water, and climate programs to strengthen forecasts, warnings, and hazard response across the United States. The bill defines “weather data,” extends and funds NOAA research and operational programs through FY2026–2030, directs new testing and pilot projects (radar interference testing, aviation weather/turbulence improvements, coastal fog forecasting, subseasonal-to-seasonal forecasting for drought and agriculture), creates/expands a NOAA Commercial Data Program to buy and test private observations, improves public warning messages and NOAA Weather Radio, builds national capacity to address harmful algal blooms and hypoxia, establishes a national heat-health coordination system and plan, and reauthorizes and updates the National Landslide Preparedness program with a specified funding level.

It sets programmatic deadlines (project plans, standards, reports), authorizes specified funding amounts for several activities through FY2026–2030, and adds new authorities for Arctic and Pacific work, interagency coordination, and data-sharing. Many provisions focus on moving research to operations, improving decision support for users (aviation, farmers, water managers, coastal communities), and integrating commercial data into federal systems.
