The 2020 Atlantic hurricane season was a slightly below-average season, and the first season since the 1976 season that two subtropical cyclones formed and did not become fully tropical. The season officially began on June 1, and ended on November 30. These dates conventionally delimit the period of each year in which most tropical cyclones form in the north Atlantic.

The strongest, costliest, and deadliest storm in the 2020 season was Hurricane Hanna, a large and powerful Category 3 hurricane that was the first major hurricane to make landfall in North Carolina since Hurricane Fran in 1996. Overall, Hanna caused $9.2 billion in damages and 41 deaths.
