The purpose of the Weather Radar Coverage Improvement Act is to enhance the capabilities of weather radar systems in the United States. This legislation aims to develop a new generation of weather radar technology and address gaps in existing radar coverage to improve weather detection and forecasting. Key provisions of the Act include a plan to replace the current Next Generation Weather Radar (NEXRAD) system by 2040. The Under Secretary, in collaboration with the National Weather Service, is tasked with creating this plan, which will outline improvements in radar coverage and accuracy.
