Fog is more opaque than mist, reducing visibility to under one kilometre. This class refers only to fog formed by materials primarily composed of water. "Fog can be considered a type of low-lying cloud and is heavily influenced by nearby bodies of water, topography, and wind conditions. In turn, fog has affected many human activities, such as shipping, travel, and warfare." https://en.wikipedia.org/wiki/Fog
