The Effects of Hurricane Irene in New York were the worst from a hurricane since Hurricane Agnes in 1972. Hurricane Irene formed from a tropical wave on August 21, 2011 in the tropical Atlantic Ocean. It moved west-northwestward, and within an environment of light wind shear and warm waters.
Shortly before becoming a hurricane, Irene struck Puerto Rico as a tropical storm. Thereafter, it steadily strengthened to reach peak winds of 120 mph (195 km/h) on August 24. Irene then gradually weakened and made landfall on the Outer Banks of North Carolina with winds of 85 mph (140 km/h) on August 27.
It slowly weakened over land and re-emerged into the Atlantic on the following day. Later on August 28, Irene was downgraded to a tropical storm and made two additional landfalls, one in New Jersey and another in New York. The storm quickly began to lose tropical characteristics and became extratropical in Vermont.
Irene produced heavy damage over much of New York, totaling to $296 million (2011 USD). The storm is ranked as one of the costliest in the history of New York, after Hurricane Agnes in 1972.
Much of the damage occurred due to flooding, both from heavy rainfall in inland areas and storm surge in New York City and on Long Island. Tropical storm force winds left at least 3 million residents without electricity in New York and Connecticut. Ten fatalities are directly attributed to the hurricane.
