Hurricane Irene (09L) is an active North Atlantic tropical cyclone that currently poses a significant threat to the Bahamas, the East Coast of the United States, including the New York metropolitan area, and Atlantic Canada.

The ninth named storm, first hurricane, and first major hurricane of the 2011 season, Irene developed from a well-defined Atlantic tropical wave, which showed signs of tropical development east of the Lesser Antilles.

It developed atmospheric convection and a closed cyclonic circulation center, prompting the National Hurricane Center to initiate public advisories on the tropical cyclone late on August 20. Subsequent convective organization occurred as it passed the Leeward Islands, and by August 21 it moved very close to Saint Croix.

The next day, when this image was acquired, Irene made landfall near Puerto Rico, where high winds and intermittent torrents caused extensive property damage. The hurricane strengthened as it passed through southeastern Bahamas, becoming a major hurricane on August 24.
