The birth and evolution of Hurricane Alex, as seen in spectacular satellite imagery

To watch the evolution of Hurricane Alex between January 6 and 14, click on the screenshot above. That will launch an animation of false-color imagery acquired by the GOES-13 weather satellite showing water vapor in the atmosphere. Blue, white and green colors show where water vapor is highest. (The animation is from the Cooperative Institute for Meteorological Satellite Studies, which runs the ever-awesome CIMSS Satellite Blog.)
