Cyclone Marcia passed us by today.  As a categoary 5 she whipped Yepoon and Rockhampton until buildings shattered and trees threw themselves to the ground.  By the time she reached us she was barely a tropical low.   And now she is trailing her grey gossamer skirts out to sea.

Does there come a point where Cyclone Marcia is reduced to one white cloud of vapor rapidly evaporating over the hot blue of the Coral Sea?  Is the reverse true?  Did she start with a collection of water droplets which became a cloud, which became a rain cloud, which became a thunderstorm?
