Improving Atmospheric River Forecasts Act

The Improving Atmospheric River Forecasts Act directs NOAA to create a program that enhances forecasts of atmospheric rivers - narrow corridors of moisture that can cause severe flooding, landslides, and infrastructure damage, particularly affecting communities along the West Coast and mountainous regions. The program will develop improved forecast models using machine learning and new data sources (like aircraft, satellites, and ocean buoys), establish coastal observatories for real-time monitoring, and create clearer public communication tools about atmospheric river risks. NOAA must submit a detailed implementation plan to Congress within 270 days, including research partnerships and timelines for deploying these upgrades. The goal is to reduce property damage and loss of life by providing more accurate, actionable forecasts for communities vulnerable to extreme weather events.
