National Aeronautics and Space Administration, (NASA): Hurricanes/Tropical Cyclones
Aug. 25, 2011, Second Update
Here, NASA’s Geostationary Operational Environmental Satellite (GOES)-13, saw Hurricane Irene moving through the Bahamas on August 25, 2011 at 1402 UTC (10:02 a.m. EDT), and far to the east, was newly born Tropical Depression 10 (far left). Irene dwarfs Tropical Depression 10, and Irene is about 1/3rd the size of the entire U.S. East coast. Putting Irene's size into a comparative perspective, the distance from Augusta, Maine to Miami, Florida is 1662.55-miles. Hurricane Irene's tropical storm-force winds extend 255 miles from the center making Irene 510 miles in diameter, almost one-third the size of the U.S. Hurricane force winds extend 70-miles from the center, or 140-miles in diameter.
