What is the purpose of an enroute weather briefing?

The purpose of an enroute weather briefing is to assess updated weather information that could affect the safety and operation of the flight while it is in progress. During an enroute briefing, pilots and dispatchers receive the most current data on weather conditions along the flight path, including potential hazards such as turbulence, thunderstorms, wind shear, and other dynamic weather phenomena that may have developed since the preflight briefing. Accessing this updated information helps ensure informed decision-making regarding route adjustments, altitude changes, and other necessary operational considerations to enhance safety and efficiency during the flight.

In contrast, historical weather data is typically of limited use for ongoing flights since conditions can change rapidly. Evaluating ground transportation options and offering in-flight meal options are unrelated to the purpose of an enroute weather briefing and do not support the immediate safety and operational needs of the flight.
