    Aviation meteorologists: Urgent actions needed to address staffing concerns

    A August 2025 U.S. Government Accountability Office report warns that staffing shortages among National Weather Service meteorologists embedded at FAA air traffic control centers may pose risks to the safety and efficiency of the National Airspace System. These meteorologists provide critical real-time weather briefings to air traffic controllers to help route flights safely around severe weather, but a February 2025 amendment to the FAA-NWS interagency agreement reduced the required staffing level from 90 to 81 positions. The GAO urges urgent action from the Departments of Transportation and Commerce before the interagency agreement expires in September 2025.

    This August 2025 technical report by Harris Miller Miller & Hanson Inc. (HMMH) presents the results of interior sound insulation testing conducted at 28 homes near Seattle-Tacoma International Airport (SEA) in July 2025.
