This bill creates official rules for a national weather monitoring network run by NOAA called the National Mesonet Program. Think of it as a system of thousands of automated weather stations scattered across the country that constantly collect information about temperature, rainfall, soil conditions, and other environmental data. Right now this network exists, but this bill gives it legal backing and sets clear standards for how it should operate.

The bill requires NOAA to use this network to improve forecasts for floods, droughts, wildfires, and water-related events. The key requirement is that NOAA can only add new data sources if they're cost-effective and meet strict quality standards—so they're not just collecting random information, but focusing on data that actually helps with predictions. The bill also mandates that at least 15% of the program's annual funding goes to states, tribes, universities, and private companies that want to build or improve their own local weather stations. These organizations have to agree to share their data with the national network, which helps create a more complete picture of weather patterns across the country.

To make sure the program stays on track, the bill requires NOAA to maintain an advisory committee of experts who recommend what kinds of data the program should collect and how to buy equipment. The bill also prioritizes funding for remote areas and places that currently don't have good weather monitoring, which means rural communities and underserved regions will get better access to weather forecasting and early warning systems for dangerous weather events.

Improving Flood and Agricultural Forecasts Act of 2025

Schatz, Brian

Improving Flood and Agricultural Forecasts Act of 2025This bill provides statutory authority for the National Mesonet Program (NMP) maintained by the National Oceanic and Atmospheric Administration (NOAA). (Mesonets are networks of automated weather and soil observation stations that collect data used in measuring, tracking, and forecasting weather and its effects. The NMP is a national network of local mesonets that collects and disseminates non-federal atmospheric weather observations in the United States.)The bill sets forth certain requirements for the NMP, including that the program must obtain weather observations in order to improve understanding and forecasting of atmospheric, drought, fire, and water events, and establish means to integrate increased numbers and types of environmental observations into the program annually. However, NOAA may obtain data under the program only when it is demonstrably cost effective and meets or exceeds certain data quality standards.&nbsp;Of funds appropriated to the program annually, NOAA must award at least 15% to state, tribal, private, and academic entities seeking to build, expand, or upgrade mesonet system equipment and capacity. Entities receiving funds must agree to provide data to the NMP. In allocating funding, NOAA must prioritize providing funds to entities in remote areas and areas that lack environmental monitoring stations.&nbsp;NOAA must also ensure the NMP has an active advisory committee, comprised of subject matter experts, to make recommendations on data needs and procurement, among other topics.&nbsp;
