Hurricane Irene: Time Lapse Video
The National Oceanic and Atmospheric Administration released a video illustrating the time lapse of Irene, from a tropical storm to a hurricane.
The imagery shows Irene's path from Puerto Rico and the Bahamas when it was a category 3 storm to North Carolina, where the storm made landfall Saturday morning as a category 1. It is now heading for the major metropolitan areas of the Northeast U.S.
NOAA GOES-East satellite documented Irene's movements from Aug. 19 to Aug. 27.
