What are the conditions indicated by 'OVC' in weather reports?

The term 'OVC' in weather reports stands for "overcast." This means that the sky is completely covered by clouds, with the cloud base typically at a height that can range from low (thousands of feet) to high elevations. When the sky is classified as overcast, there are no breaks or gaps in the cloud cover, which can significantly influence flight operations and visibility.

In a weather report, 'OVC' is an important condition for pilots and air traffic controllers as it indicates that the visibility may be reduced and that the overall weather conditions could be less than ideal for flying. Understanding this term is essential for planning and conducting safe aviation activities.
