Which hurricane devastated Charleston, South Carolina in 1989?

Hurricane Hugo was a powerful Cape Verde-type hurricane that caused widespread damage and loss of life in the Leeward Islands, Puerto Rico, and the Southeast United States. Hugo moved thousands of miles across the Atlantic, rapidly strengthening to briefly attain category 5 hurricane strength on its journey. It later crossed over Guadeloupe and St. Croix on September 17 and 18 as a category 4 hurricane. Weakening slightly more, it passed over Puerto Rico as a strong category 3 hurricane. However, it re-strengthened into a category 4 hurricane before making landfall just slightly north of Charleston, on Sullivans Island September 21 with 140 mph sustained winds (gusts to more than 160 mph). It had devolved to a remnant low near Lake Erie by the next day. As of 2016, Hurricane Hugo is the most intense tropical cyclone to strike the East Coast north of Florida since 1900.

Hurricane Hugo caused 34 fatalities (most by electrocution or drowning) in the Caribbean and 27 in South Carolina, left nearly 100,000 homeless, and resulted in $10 billion (1989 USD) in damage overall, making it the most damaging hurricane ever recorded at the time. Of this total, $7 billion was from the United States and Puerto Rico, ranking it as the costliest storm to impact the country at the time. Since 1989, however, it has been surpassed by multiple storms and now ranks as the eleventh costliest in the United States.
