Improving Flood and Agricultural Forecasts Act of 2025

S 613, the Improving Flood and Agricultural Forecasts Act of 2025, expands weather monitoring networks to enhance flood and agricultural forecasts. It directs the Under Secretary to fund and coordinate a National Mesonet Program that collects more ground-level weather data - like soil moisture, road conditions, and local atmospheric observations - from state, tribal, private, and academic partners. The bill requires grantees (including local networks) to share data with federal agencies in exchange for 15% of annual funding (up to $70 million by 2029), aiming to improve severe weather warnings (targeting 30-minute lead times) and support farmers, emergency managers, and transportation sectors. Key provisions include integrating commercial data, prioritizing remote areas with sparse monitoring, and annual congressional briefings on progress.
