What is ATC's protocol for handling inclement weather affecting traffic flow?

The protocol for handling inclement weather affecting traffic flow involves rerouting aircraft or implementing holding patterns. This approach is essential for ensuring safety and efficient traffic management. When adverse weather conditions arise, such as thunderstorms, fog, or heavy snowfall, air traffic controllers must proactively manage the flow of air traffic to avoid potential accidents and maintain safe separation between aircraft.

Implementing holding patterns allows controllers to delay aircraft arrivals in a controlled manner, reducing the risk of congestion and ensuring that flights can land safely when conditions improve. Additionally, rerouting aircraft may be necessary to direct them away from hazardous weather areas, thereby enhancing safety and minimizing disruptions. This strategic adjustment to flight paths or arrivals provides controllers with the flexibility needed to adapt to changing weather situations while prioritizing safety and maintaining orderly traffic flow.
