If an AIRMET/SIGMET/Convective SIGMET is issued as part of an Area Forecast, it means that the specified weather conditions are expected to exist in the forecast area. However, it does not guarantee that these conditions will be present along a specific route of flight. Pilots must consult the latest weather information and observe any relevant NOTAMs to determine if the conditions will affect their planned route. They should also consider alternate routes or delaying the flight if necessary.
