1989 Atlantic hurricane season

The 1989 Atlantic hurricane season was an average hurricane season with 11 named storms. The season officially began on June 1, and ended on November 30. The first tropical cyclone, Tropical Depression One, developed on June 15, and dissipated two days later without any effects on land. Later that month, Tropical Storm Allison caused severe flooding, especially in Texas and Louisiana. Tropical Storm Barry, Tropical Depressions Six, Nine, and Thirteen, and Hurricanes Erin and Felix caused negligible impact. Hurricane Gabrielle and Tropical Storm Iris caused light effects on land, with the former resulting in nine fatalities from rip currents offshore the East Coast of the United States and Atlantic Canada, while the latter produced minor flooding in the United States Virgin Islands.

The most notable storm of the season was Hurricane Hugo, which became the costliest Atlantic hurricane on record at the time (surpassed by Hurricane Andrew in 1992), causing $9.47 billion (1989 USD) in damage and 88 fatalities as it ravaged some of the Leeward Islands and the United States, especially the state of South Carolina as a Category 4 hurricane. Few other storms in 1989 caused significant damage; hurricanes Chantal and Jerry both resulted in flooding and wind impacts in Texas. Hurricane Dean also caused light damage in Bermuda and the Canadian province of Newfoundland. Tropical Storm Karen, the final storm of the season, brought heavy rainfall and a tornado to Cuba, before dissipating on December 4. Overall, the storms of the season collectively caused 136 fatalities and at least $10.2 billion in damage.
