FAA Guidance and Real-Time Monitoring
The
FAA did not link all delays and cancellations reported by FlightAware specifically to weather conditions but highlighted the impact of low clouds at several major airports. The agency’s National Airspace System dashboard provides real-time updates on airport constraints and traffic management programs to assist airlines and controllers in managing traffic flow amid challenging weather.
