Hurricane Hanna was the deadliest storm of the 2008 Atlantic hurricane season. The storm was the eighth tropical cyclone and fourth hurricane of the 2008 Atlantic hurricane season. It formed east-northeast of the northern Leeward Islands on August 28. The cyclone struck Myrtle Beach, South Carolina, before moving up the Eastern Seaboard to become an extratropical cyclone as it moved by New England into Atlantic Canada early on September 7. The system raced across the North Atlantic, sweeping west of Great Britain on September 10 before turning north and becoming absorbed by a stronger extratropical cyclone between Iceland and Greenland late on September 12. At least 537 deaths were reported (the final death toll will likely never be known), mostly due to flooding in the northern part of Haiti, making it the deadliest tropical cyclone in the Atlantic basin since Hurricane Stan in 2005. Hanna also caused $160 million in damages to the U.S, but the exact damage in Haiti is unknown. The next hurricane to impact the New York area was Hurricane Irene in 2011.

During late August 2008, a tropical wave emerged off the coast of Africa and tracked westward across the Atlantic Ocean. After several days, an associated area of low pressure gained deep convection and organization. On August 28, while to the east-northeast of the northern Leeward Islands, the low formed into Tropical Depression Eight. Later that day, it attained tropical storm status, and as such was named Hanna by the National Hurricane Center. At the time, the low-level center of circulation was partially exposed on the western edge of the convection, indicating westerly wind shear.
