VMC is a shortcut for --->'Visual Meteorological Conditions'.
In the maritime context, VMC refers to the visibility conditions required for safe navigation and is often used in weather reports and forecasts. Specifically, VMC means that the visibility is equal to or greater than three nautical miles, and the cloud ceiling is at least 1,000 feet above ground level. VMC is an important consideration for pilots, navigators, and other maritime professionals as it impacts the safety and efficiency of maritime operations.
