Green fog is a very rare occurrence that occurs around the countryside in Red and Flint counties, mainly in rivers and lakes. The fog is rumored to be a chemical residual of nearby chemical plants in the area and may a reference to water pollution. There are very few photos and videos that show this strange phenomenon occurring. A neon green fog can be observed during the mission First Base. A suicidal pedestrian can also be perceived in the fog, by the river.
Several green clouds can also be seen at night in GTA Vice City, although their purpose in the game is still unknown. They are often linked to the Bermuda Triangle and hurricane myth. The cloud may very well be the shadow of the sea color at night.
