To be noted Tropical Depression 18 has developed in the Caribbean Sea while the water vapor was moving from the Greenland-Iceland icesheets and glaciers. The formation of 18 began before the water vapor movement. While it was a formation, it lacked the water vapor content to build to a tropical storm.
