Hurricane Irene was a large and destructive tropical cyclone, which affected much of the Caribbean and East Coast of the United States during late August 2011.
 Irene is ranked as the ninth-costliest hurricane in United States history.
 The ninth named storm, first hurricane, and first major hurricane of the 2011 Atlantic hurricane season, Irene originated from a well-defined Atlantic tropical wave that began showing signs of organization east of the Lesser Antilles.
 Due to development of atmospheric convection and a closed center of circulation, the system was designated as Tropical Storm Irene on August 20, 2011.
 After intensifying, Irene made landfall in St. Croix as a strong tropical storm later that day.
 Early on August 21, the storm made a second landfall in Puerto Rico.
 While crossing the island, Irene strengthened into a Category 1 hurricane.
 The storm paralleled offshore of Hispaniola, continuing to slowly intensify in the process.
 Shortly before making four landfalls in the Bahamas, Irene peaked as a 120 mph Category 3 hurricane.
