In a weather report, what does "OVC" stand for?

"OVC" in a weather report stands for "Overcast clouds." This term indicates that the sky is completely covered by clouds, meaning there are no breaks or holes in the cloud cover. When the weather report states that the sky is overcast, it generally signifies the presence of a uniform layer of clouds, which can lead to reduced visibility and potentially impact flight operations since pilots often rely on visual references. Understanding this terminology is crucial for any drone operator, as weather conditions significantly affect flight safety and planning.
