Which weather conditions should controllers be familiar with when coming on duty?

Being familiar with all current weather conditions in their sector and surrounding sectors is crucial for controllers. This knowledge enables them to make informed decisions regarding aircraft movements and ensure the safety of operations. Weather can change rapidly and can influence flight paths, delays, and necessitate coordination with other sectors.

Understanding the weather in their own sector allows controllers to manage immediate operations effectively, but being aware of conditions in surrounding sectors provides a broader context that could affect traffic flow and potential hazards. For example, if there is severe turbulence, storms, or low visibility in a nearby sector, controllers need to factor that into their planning and communication with pilots and other controllers.

Thus, familiarity with the full weather panorama enhances situational awareness, aids in risk management, and improves overall air traffic management efficiency.
