Hurricane Hugo was a powerful tropical cyclone that inflicted widespread destruction across the northeastern Caribbean and the Southeastern United States in September 1989. The eleventh tropical cyclone, eighth named storm, sixth hurricane, and second major hurricane of the 1989 Atlantic hurricane season, Hugo arose from a cluster of thunderstorms near Cape Verde on September 10, 1989. This cluster coalesced into a tropical depression and strengthened into Tropical Storm Hugo as it tracked west across the Atlantic Ocean for several days. On September 13, Hugo became a hurricane and continued to intensify through September 15 when its sustained winds peaked at 160 mph (255 km/h), making it a Category 5 hurricane on the Saffir–Simpson scale. Between September 17 and 21, Hugo made landfall on Guadeloupe, Saint Croix, Puerto Rico, and lastly South Carolina, with major hurricane strength winds. The storm weakened inland and accelerated north over the Eastern United States, transitioning into an extratropical cyclone on September 23 before it was last noted in the far northern Atlantic on September 25.
Hugo left extensive damage in its wake, causing 61 deaths and $11 billion (equivalent to $28 billion in 2024) in damage, which at the time, made it the costliest tropical cyclone on record worldwide. Guadeloupe bore the brunt of the storm in the Leeward Islands. Three thousand houses were unroofed, contributing to the displacement of 35,000 people from their homes. Hugo was Montserrat's costliest hurricane on record and brought down the island's entire power grid. Ninety percent of homes on the island suffered significant to total roof loss after the island was struck by the eyewall. The hurricane's impacts continued into the Virgin Islands and Puerto Rico, causing over $1 billion in damage. Wind gusts up to 168 mph (270 km/h) were measured in Saint Croix, where property damage exceeded $500 million with over 90 percent of buildings damaged; three people were killed on the island. Widespread damage occurred in Puerto Rico and much of the island suffered power and water service failures. Eight people were killed in Puerto Rico and nearly 28,000 people were left homeless. In the mainland United States, coastal South Carolina was hit by record setting storm surge heights, reaching 20.2 ft (6.2 m) near McClellanville. The surge and strong winds wrought extensive damage to buildings and infrastructure across South Carolina, and caused 13 deaths. Flood and wind impacts followed Hugo across much of the Eastern United States into Eastern Canada.
