Scene notes:

Heat, moisture, and more heat. The Everglades have this in spades. Seen here, the clouds are truly towering in their nature, being taller than they are wide at their base. These updrafts play out as visible clouds and will grow to form rain clouds. Tropical land warming accelerates these clouds around the Everglades, and the warm waters assist in visible absolute humidity.
