Weather Radar Coverage Improvement Act

HR 4575, the Weather Radar Coverage Improvement Act, directs the National Weather Service to replace the aging NEXRAD radar system with new digital phased array technology by September 30, 2040. The bill requires developing a plan including coverage improvement estimates, creating a testbed for evaluating commercial radars, and prioritizing third-party contracts to fill coverage gaps using diverse radar technologies. This directly affects the National Weather Service, which must implement the replacement, and communities in areas with current radar coverage gaps. The key provision allows contracting private companies ("Radar-as-a-Service") to supplement radar coverage, particularly in geographically challenging regions.
