Aug. 23, 2011, second update

This image of Hurricane Irene was captured from NASA's Terra satellite, when the storm's center had passed Puerto Rico at 15:20 UTC (11:20 a.m. EDT), on Aug. 22, 2011. The southern quadrant of Irene's clouds were still over the island bringing heavy rainfall. There is no eye visible in the image. NASA satellites have been gathering data on Hurricane Irene, as she heads towards the Bahamas today and tomorrow and observed that she is a large hurricane.

Irene's hurricane force winds extend outward up to 50 miles (85 km) from the center and tropical storm force winds extend outward up to 205 miles (335 km). That means that Irene is about 410 miles in diameter. That's just shy of the distance from Washington, D.C. to Boston, Mass.
