When is volcanic ash reported?

Volcanic ash is reported whenever it occurs because it is a significant hazard to aviation and can affect flight safety regardless of the time of day or visibility conditions. The presence of volcanic ash can cause serious issues for aircraft, including engine failure, so timely reporting is essential to ensure that pilots can avoid areas where ash is present. This reporting is not limited to specific visibility thresholds or severe weather events; rather, it is crucial to monitor and report ash as soon as it is detected to maintain flight safety and inform air traffic operations.
