The Rapid Refresh Forecast System (RRFS) is the NOAA next-generation convection-allowing, rapidly-updated prediction system. The operational configuration will feature a 3-km grid covering North America with both deterministic and ensemble forecasts. The RRFS is underpinned by the Unified Forecast System (UFS), a community-based Earth modeling initiative, and benefits from collaborative development efforts across NOAA, academia, and research institutions.
